Penthouse

Penthouse (pronounced pent-hous)

(1) An apartment or dwelling on the roof of a building, usually set back from the outer walls.

(2) Any specially designed apartment on an upper floor, especially the top floor, of a building.

(3) A structure on a roof for housing elevator machinery, a water tank etc.

(4) Any roof-like shelter or overhanging part.

(5) In real tennis, a corridor having a slanted roof and projecting from three walls of the court.

(6) As mechanical penthouse, a floor, usually directly under a flat-roof, used to house mechanical plant & equipment.

(7) A special-interest magazine, aimed at a mostly male audience and published in several editions by a variety of owners between 1965-2023.

1520–1530: Despite the appearance penthouse is not a portmanteau (pent + house) word.  Penthouse is an alteration (by folk etymology) of the Middle English pentis, pentiz & pendize (and other spellings), from the Old French apentiz & apentis (appendage, attached building), the construct being apent (past participle of apendre (to hang against)) + -iz (the French -is ) from the unattested Vulgar Latin –ātīcium (noun use of neuter of the unattested –ātīcius, the construct being the Latin -āt(us) (past participle suffix) + -īcius (the adjectival suffix)).  Old French picked up apentis from the Medieval Latin appendicium (from the Classical Latin appendo (to hang) & appendere (to hang from).  A less common alternative variant to describe a shed with a sloping roof projecting from a wall or the side of a building was pentice.  Penthouse is a noun & verb, penthousing is a verb and penthoused & penthouslike are adjective; the noun plural is penthouses.  The adjectives penthouseish & penthousesque are non-standard.

Penthouse magazine, December 1993.

First published in 1965, Penthouse magazine was one of many ventures (in many fields) which proved unwilling or unable to adapt to the changes wrought by the internet and the atomization of the delivery of content; its last print edition (after a few stuttering years) appeared in 2023 although there must remain some perception of value in the name because of the decades-long prominence of the title and it's not impossible there will be a revival, even if it's unlikely to re-appear in the glossy magazine format of old.  In Australia, for students of the print industry the comparison between the “men’s magazines” Penthouse and Playboy (first published in 1953, on-line since 2020 and a print “annual edition” appeared in 2025) was something like that between the “women’s magazines” Cosmopolitan (since 1965 in its current niche) and Cleo (1972-2016) in that the two pairings were superficially similar but different in emphasis.  Not too much should be made of that because although identifiably there were “Cosmo women” & “Cleo women” (presumably with some overlap at the margins), between Penthouse and Playboy there were probably more similarities than variations.  Structuralists explained the difference between the two genres: “men’s magazines” were bought by men so they could look at pictures of women not wearing clothes while “women’s magazines” were bought by women so they could look at pictures of women wearing clothes.

When the lovely Ms Schiffer appeared on the cover of the December 1993 edition of Penthouse, the editors may not have been aware of the beast which was coming to consume them but it was in April 1993 CERN (in 1953 the Conseil Européen pour la Recherche Nucléaire (European Council for Nuclear Research) but the following year re-named Organisation européenne pour la recherche nucléaire (European Organization for Nuclear Research) with the acronym retained because it was both more mnemonic and pronounceable than OERN) released into the public domain details of technology which would allow the free development of applications using the www (world wide web) which ran atop the internet, making indexed content more easily accessible and distributable.  When in April 1993 the NCSA (National Center for Supercomputing Applications) released version 1.0 of its Mosaic web browser, it triggered a social and industrial revolution which (variously on TikTok, X (formerly known as Twitter), FoxNews and such) continues to unfold.  Mosaic wasn’t the first web browser but it was the first to gain a critical mass and the applications which superseded it claimed many victims including Penthouse magazine.

Iso, the Grifo and the Penthouse

1965 Iso Grifo Bizzarini A3/C, Le Mans, 1965.

One of the most admired of the trans-Atlantic hybrids of the post-war years (1945-1973) which combined elegant coachwork, (hopefully) high standards of craftsmanship and the effortless, low-cost power of large-displacement American V8 engines, the Iso Grifo was produced between 1965-1974 by the Italian manufacturer Iso Autoveicoli.  Styled by Bertone’s Giorgetto Giugiaro (b 1938) with engineering handled by the gifted Giotto Bizzarrini (1926-2023), the Grifo initially used a 327 cubic inch (5.3 litre) version of the small-block Chevrolet V8, coupled with the equally ubiquitous Borg-Warner (four & five speed) manual gearbox or robust General Motors (GM) Turbo-Hydramatic automatics.  Later, after some had been built with the big-block Chevrolet V8, GM began to insist on being paid up-front for hardware so Iso negotiated with the more accommodating Ford Motor Company (FoMoCo) and switched to 351 cubic inch (5.8 litre) versions of their 335 (Cleveland) engine.

1955 Iso Isetta.

Iso was already familiar with the mechanical configuration, production of their Rivolta coupe, equipped also with the Chevrolet 327, having begun in 1962.  The Rivolta, let alone the Grifo was quite a change of direction for Iso which until then had produced a variety of appliances, scooters & moto-cycles, it’s most famous product the Isetta, one of the generation of “bubble cars” which played such a part in putting Europeans back on (three or four) wheels during the re-construction of the early post-war years.  Surprisingly, despite the prominence of the Isetta name and the Italian association, barely a thousand were actually manufactured by Iso, the overwhelming majority produced in many countries by BMW and others to which a license was granted.  The bubble cars were a product of the economic circumstances of post-war Europe and the ones produced in England even used the single rear wheel which had been abandoned by Iso because of the inherent instability; UK taxation laws made three-wheelers significantly cheaper and only a motor-cycle license was required to drive one.  Powered by tiny two and four-stroke engines, their popularity waned as “real” cars such as the Fiat 500 (1955-1975) and later the BMC (British Motor Corporation) Mini (1959-2000) emerged; although costing little more than the bubble cars, they offered more space, performance and practicality.  By the early 1960s, the bubble cars were almost extinct but, as a tiny specialized niche, they never completely vanished and the Isetta is enjoying a twenty-first century revival as model urban transportation, including the option of (Greta Thunberg (b 2003) approved) electric propulsion.  Once dismissed as dated and even absurd, their bug-eyed look is now thought to have "retro-charm".

1968 Iso Rivolta.

The Rivolta was thus quite a jump up-market and, while the engine wasn't the bespoke thoroughbred found in a Ferrari or Aston-Martin, the rest of the specification justified the high price.  Unlike some of the British interpretations using American V8s, Iso insisted on modernity, the platform probably the best of the era with a body welded to a pressed-steel chassis, a combination which proved both light and stiff.  Just as importantly, given the high rate of corporate failure among those attracted to this potentially lucrative market, it was cost-effective to manufacture, reliable and easy to service.  Probably the feature which let it rank with the most accomplished of the era was the sophisticated de Dion rear suspension which, combined with four wheel disc brakes, lent it a rare competence (surprising some Maserati and Ferrari drivers, their cars with rear suspension designs dating from the horse & buggy era).  The de Dion design was not an independent arrangement but certainly behaved as if it was and, despite what Mercedes-Benz claimed of their beloved swing-axles, was superior to many of the independent setups on offer.  A noted benefit of the de Dion system is it ensures the rear wheels remain always parallel, quite an important feature in an axle which has to transmit to the road the high torque output of a big V8, a lesson Swiss constructor Peter Monteverdi (1934–1998) applied later in the decade when he went into production using even bigger engines.  Iso, with a solid base in accounting and production-line economics, ran an efficient and profitable operation not beset by the recurrent financial crises which afflicted so many and the elegant Rivolta was a success, remaining available until 1970.  Some eight hundred were sold.

1967 Iso Grifo Series One.

The Rivolta’s platform proved adaptable.  In 1965, Iso released the Grifo coupé which was more overtly oriented to outright performance and strictly a two-seater.  With lovely lines and a modified version of the Rivolta’s fine chassis, the Grifo was another product of the fertile imaginations of Giugiaro & Bizzarrini but, in something not untypical in Italian industry of the time, the relationship between the latter and Iso’s founder Renzo Rivolta (1908–1966) soon became strained and was sundered.  Bizzarrini would go on to do remarkable things and Iso’s engineers assumed complete control of the Grifo after the first few dozen had been completed.  Bizzarrini had pursued a twin-stream development, a competition version called the A3/C with a lower, lightweight aluminum body as well as the road-going A3/L and when he decamped, he took with him the A3/C, to be released also under his name while Iso devoted its attentions to the A3/L, again using engine-transmission combinations borrowed from the Chevrolet Corvette.

1964 Iso Grifo A3/L Spider prototype by Bertone.

The Grifo weighed a relatively svelte 1430 kg (3153 lbs) in what must have been a reasonably slippery shape because the reports at the time confirmed some 240 km/h (150 mph) was easily attained, an increase on that managed by the C2 Corvette (1962-1967 and which turned out to be not aerodynamically efficient as it looked) and, when configured with the taller gearing the factory offered, the factory claimed 260 km/h (162 mph), was possible.  A test in the UK in 1966 almost matched that with a verified 161 mph (259 km/h) recorded and two years later, the US publication Car & Driver 1968 tested a 327 Grifo but didn't to a top-speed run, instead estimating 157 mph (253 km/h) should be possible given enough road.  There were surprisingly few variations, fewer than two-dozen made with a targa-style removable roof panel and a single, achingly lovely roadster was displayed on Bertone's stand at the 1964 Geneva Motor Show; it remained a one-off although a couple of coupés privately have been converted.  What made the Bertone prototype special however was it was a companion to the original A3/L prototype coupé with which it shared a number of distinctive features including (1) a side exhaust rakishly snaking through the passenger side of the cowl and under the rocker panel trim with its an almost matte finish, (2) frontal styling with the then fashionable “twin-nostril” fascia and (3) angled vents in the rear fenders.  Although visually similar to the series production Grifos, almost every line on the pair of A3/L prototypes was in some subtle way different.

The one-off Iso Grifo Spider on Bertone's stand, 1964 Geneva Salon, 1964 (left) and as discovered in Rudi Klein's famous shed, Los Angeles, 2024 (right). 

Although well-known in the collector community for its large stocks of rusty and wrecked Porsches, Mercedes-Benz and other notable vehicles from the post-war years, the Californian “junkyard” belonging to Rudi Klein (1936-2001) attracted world-wide interest when details were published of the gems which had for decades been secreted in the site's large and secure shed.  Mr Klein was a German butcher who in the late 1950s emigrated to the US to work at his trade but quickly discovered a more enjoyable and lucrative living could be had dealing in damaged or wrecked European cars, sometimes selling the whole vehicles and sometimes the parts (“parting out” in junkyard parlance).  His Porsche Foreign Auto business had operated for some time before he received a C&D (cease & desist) letter from the German manufacturer’s US attorneys, the result being the name change in 1967 to Porche (sic) Foreign Auto.  Unlike many collectors, Mr Klein amassed his collection unobtrusively and, astonishingly to many, apparently with little interest in turning a profit on the rarest, despite some of them coming to be worth millions.  After Mr Klein died in 2001, his two sons preserved the collection untouched until, in October 2024,the auction house Sotheby’s began a series of rolling sales, one to go under the hammer the one-off Grifo spider.  At some point there was an accident which damaged the nose so a standard Grifo facia was installed and in this form Mr Klein ran it for a while as a road car before parking it in the shed among its illustrious companions.  Remarkably original except for the nose, it sold for US$1,875,000 and the expectation is it will be fully restored (including a fabricated replica of the original nose) before appearing on the show circuit.  In the decades to come, it will likely spend its time in collections with the occasional outings to auction houses.

1970 Iso Grifo Targa (left) Series Two and 1971 Iso Grifo Can-Am (454) Targa.  Only four Series II Can-Ams were built with the targa roof.

The bodywork was revised in 1970, subsequent cars listed as Series Two models.  The revisions included detail changes to the interior, improvements to the increasingly popular air-conditioning system and some alterations to the body structure, the hydraulics and electrical system, some necessitated by new regulatory requirements in Europe but required mostly in an attempt to remain compliant with the more onerous US legislation.  The most obvious change was to the nose, the headlamps now partially concealed by flaps which raised automatically when the lights were activated.  Presumably the smoother nose delivered improved aerodynamics but the factory made no specific claims, either about performance or the drag co-efficient (CD) number.

1972 Iso Lele & 1972 Iso Fidia.

In 1972, an unexpected change in the power-train was announced.  After almost a decade exclusively using Chevrolet engines, Iso issued a press release confirming that henceforth, the Series Two Grifo would be powered by Ford’s Boss 351 cubic inch (5.8 litre) 335 series (Cleveland) V8.  In the state of tune (close to that fellow Italian specialist De Tomaso were using in their mid-engined Pantera) chosen, the Ford engine was similar in size, weight to the small-block Chevrolet and delivered similar power and torque characteristics so the driving experience differed little although there were 22 high-performance Leles using a tuned 351, all with a ZF five-speed manual gearbox.  The other improvement in performance was presumably Iso’s balance sheet.  The switch had been made because internal policy changes at GM meant they were now insisting on being paid up-front for their product whereas Ford was still prepared to mail an invoice with a payment term.  The change extended to the other models in the range, the Lele coupé and Fidia saloon and while the Chevrolet/Ford split in the Lele was 125/157, the circumstances of the time meant that of the 192 Fidias made, only 35 were fitted with the 351.

1969 Iso Grifo 7 Litre (427).

One of the trends which made machines of the 1960s so memorable was a tendency never to do in moderation what could be done in excess.  In 1968, Iso announced the Grifo 7 Litre, built following the example of the US manufacturers who had with little more than a pencil and the back of an envelope worked out the economics of simple seven litre engines were more compelling than adding expensive components like overhead camshafts and fuel-injection to five litre engines; in the US, gas (petrol) was then relatively cheap and and assumed by most to be limitless.  Gas wasn’t as cheap in Italy or the rest of Europe but Iso’s target market for the Grifo was those who either could afford the running costs or (increasingly) paid their bills with OPM (other people’s money) so in those circles fuel consumption wasn’t something often considered or much discussed.  The new version used a 427 cubic inch (7.0 litre) version of the big-block Chevrolet V8, bigger and heavier than the 327 so the driving characteristics of the nose-heavy machine were changed but contemporary reports praised the competence of the chassis, the de Dion rear-end notably superior in behavior compared with the Corvette’s independent rear suspension although some did note it took skill (which meant often using some restraint) effectively to use the prodigious power.  Tellingly, the most receptive market for the Grifos, small and big-block, was the  FRG (Bundesrepublik Deutschland (Federal Republic of Germany; the old West Germany) 1949-1990) with its network of highways without the tiresome speed limits elsewhere imposed and (even in Italy), often enforced.  The Autobahn really was the Grifo's native environment.

1971 Iso Grifo Can Am (454).

Faster it certainly was although the factory’s claim of a top speed of 186 mph (a convenient 300 km/h) did seem optimistic to anyone with a slide-rule and there appears not to be any record of anyone verifying the number although one published test did claim to have seen well over 255 km/h (150 mph) with the Grifo still "strongly accelerating" before “running out of road”.  It had by then become a genuine problem.  Gone were the happy times when testers still did their work on public roads; increased traffic volumes by the late 1960s meant the often deserted stretches of highway (in 1956 an English journalist had taken a Mercedes-Benz 300SLR Coupé to 183 mph (294 km/h) on the autobahn) were now rare but whatever the terminal velocity, nobody seemed to suggest the 7 litre Grifo lacked power.  In 1970, after Iso’s stock of the by-then out-of-production triple carburetor 427 were exhausted, the big-block car was re-named Can-Am and equipped instead with a 454 cubic inch (7.5 litre) version, the name an allusion to the unlimited displacement Group 7 sports car racing series run in North America in which the big-block Chevrolets were long the dominant engine.

Despite the increased displacement, power actually dropped a little because the 454 was detuned a little to meet the then still modest anti-emission regulations.  Officially, the 454 was rated at 395 HP (gross horsepower) but the numbers in that era were often at best indicative: The Boss 429 Mustang was said to produce 375 HP whereas the 500 cubic inch (8.2 litre) V8 in the FWD! (front-wheel-drive) Cadillac Eldorado was rated at 400; a comparison of their performance belies the numbers and the difference is not all accounted for by the Eldorado's weight and power-sapping accessories.  As early as the the mid-1960s Detroit had begun understating the output of many of their high-performance engines and as politicians and insurance companies (for their own reasons) became interested, the trend continued.    

1971 Iso Grifo Can Am (454).

Unlike the 427 which breathed through three two barrel carburetors, the 454 was equipped with less intricate induction, a single four barrel and while with output (officially) dropping from 435 to 395 HP, performance was s little blunted although it's probable few owners often went fast enough to tell the difference.  What didn’t change between the 7 Litre and the Can Am was its most distinctive feature, the modification to the hood (bonnet) made to ensure the additional height of the 427's induction system could be accommodated.  The raised central section, the factory dubbed "the penthouse".

Penthouse on 1969 Iso Grifo 7 Litre (427).

Not everyone admired the stark simplicity, supposing, not unreasonably, Giugiaro might have done something more in sympathy with its surroundings.  Critics more stern would have preferred a curvaceous scoop, blister or bulge and thought the penthouse amateurish, an angular discordance bolted unhappily atop Giugiaro’s flowing lines  but for those brought up in the tradition of brutalist functionalism, it seemed an admirable tribute to what lay beneath.  The days of the big-block Grifo were however numbered.  In 1972, with Chevrolet no longer willing to extent credit and Ford’s big-block (429 & 460) engines re-tuned as low-emission (for the time) units suitable for pickup trucks and luxury cars, the Can-Am was retired.  So the small-block 351 Grifo became the sole model in the range but it too fell victim to changing times, production lasting not long beyond the first oil shock (triggered by the OAPEC (Organization of Arab Petroleum Exporting Countries) on 17 October 1973 imposing an embargo on crude oil exports to certain countries) which made gas suddenly not only much more expensive but sometimes also scarce and the whole ecosystem of the thirsty trans-Atlantic hybrids became threatened; in little more than a year, Iso was one of the many dinosaurs driven extinct.  Decades later, the survivors of the 414 sold are highly desirable; fine examples of the small-block Grifos attract over US$500,000, the few dozen penthouse have sold for close to a million and the rare early A3/Cs for even more.

From the lost, tactile days of buttons and toggle switches: 1966 Iso Grifo, one of 31 built in RHD (right hand drive).

Not fans of brutalist functionalism were the Lancia-loving types at Road & Track (R&T) magazine in the US.  Late in 1974, R&T published their 1975 buyer’s guide for imported and domestically-built smaller cars (R&T neither approving of nor understanding why anyone would wish to buy a big American car) and surprisingly, there were reviews of the Grifo, Lele and Fidia although the last of these sold in the US some two years earlier had been titled as 1973 models, the company having never sought to certification to continue sales although, given nothing had been done to modify them to meet the new safety regulations, that would likely have been pointless unless the strategy was to seek a "low volume" exemption, something improbable by 1975.

A tale of two penthouses: Paradoxically, as installed in the Grifo the induction system of the big-block Chevrolet V8 sat a little lower than that of the small-block Ford (a not unusual anomaly in the small-block vs big-block world) so the Ford-engined Grifos (right) used a taller penthouse than those fitted with the Chevrolet unit.     

The distributors had however indicated to the press all three would return to the US market in 1975, supplying publicity photographs which included a Series II "penthouse" Grifo.  A further complication was that during 1974, Ford had discontinued in the US production of the high-performance 351 (the "Cleveland" 335 series which was exiled to Australia) V8 so it wasn't clear what power-train would have been used.  Others had the same problem, De Tomaso (which withdrew from the US market in 1974) switching to use tuned versions of the Australian-built 351s but for Iso, the whole issue became irrelevant as the factory was closed late in 1974.  R&T's last thoughts on the penthouse appeared in the buyer's guide: "However, the clean lines of the original Grifo have been spoiled by that terrible looking outgrowth on the hood used for air cleaner clearance.  For US$28,500 (around US$155,000 in 2025 US$ although direct translation of value is difficult to calculate because of the influence of exchange rates and other variables), a better solution to this problem should have been found."

Isolastic

Isolastic (pronounced ahy-soh las-tik)

An engine-mounting system developed for the Norton Commando motorcycle.

1967: The construct was iso- + e(lastic).  The prefix iso- was from the Ancient Greek, a combining form of ἴσος (ísos) (equal).  Elastic (also as elastik) was from the mid seventeenth century French (coined as part of the technical language of chemistry to describe gases “having the property of recovering its former volume after compression”), from the New Latin elasticus (expanding spontaneously), the construct being the Ancient Greek elast(ós) (a late variant of elatós (ductile, beaten (of metal)) and derivative of elaúnein & elân (beat out, forge, render from metal)) + -icus (-ic-).  The Greek elastos (ductile, flexible) & elaunein are of uncertain origin but some speculate the source was the primitive Indo-European base ele- (to go).  Elastic (and elastik) came to be applied to solids after the 1660s in the sense of "possessing the nature to return to the form from which it is stretched or bent after the applied force is removed".  Figurative use to describe things as diverse as the principles of politicians or statistical properties emerged by 1859 and the most widely used modern form, the noun meaning "piece of elastic material" (originally a cord or string woven with rubber) dates from 1847 as an invention of American English.  The noun elasticity (the property of being elastic) dates from the 1660s, either from the French élasticité or else as the ad-hoc construction from elastic + -ity.  The adjective inelastic began in 1748 as part of the jargon of physical science and engineering meaning “not restored to original shape after responding to strain" and was simply the technical antonym of elastic while the figurative sense of "rigid, unyielding" dates from 1867 but general use didn’t endure as the word became associated with fields such as economics.

In scientific use, the prefix iso- was used to indicate “equal (as in isometric, isobar, isocyanic acid etc); having equal measurements”.  As a word and abbreviation, iso had its quirks even before it became popular oral shorthand to refer to the various states of isolation imposed during the early months of the COVID-19 pandemic.  The use to describe the specifications of standards (eg ISO 9001 etc) defined by the Organisation internationale de normalisation (International Organization for Standardization) leads many to believe ISO is an acronym or initializm.  However, the organization notes that when founded, it was given approved the short form “ISO”, a nod to the Ancient Greek ἴσος (ísos) (equal), the implication being the equalization (ie standardization) of rules and terminology across jurisdictions.  Despite that, there appears to be no documentary evidence to support the pedigree of the name and most folk who give the matter a moment’s thought probably assume it means “International Standards Organization”.

In film and television production, an “iso” is an isolated camera (a camera used to isolate a subject, usually for instant replay, a use dating from 1967 in sports broadcasting).  In executive salary packaging, tax minimization etc, an ISO incentive stock option) is a right extended to an employee to buy shares of company stock at a discounted price (the realized profit on which are taxed usually at a concessional rate).  In a number of sports, iso is used as a clipping of isolation to refer to tactical plays and in category theory it’s a clipping of isomorphism (morph a back-formation from morpheme, from the Ancient Greek μορφή (morphḗ) (form, shape).  In optics, isochromatic (iso- +‎ chromatic) refers to "possessing the same colour or wavelength; of or corresponding to constant colour".  Chromatic was from either the French chromatique (chromatic) or directly from its etymon the Latin chrōmaticus, from Ancient Greek χρωματικός (khrōmatikós) (relating to colour; one of the three types of tetrachord in Greek music), from χρῶμα (khrôma), (colour; pigment; chromatic scale in music; music), ultimately from the primitive Indo-European ger- (to grind; to rub; to stroke; to remove), presumably in the sense in which pigments were found.

1966 Iso Grifo Spyder (left), 1971 Iso Fidia (centre) & 1973 Iso Grifo 7 Litre (penthouse).

Iso Autoveicoli SpA (subsequently several times re-named) was an automobile and motorcycle maker in Italy, active between 1939-1974, their most fondly remembered cars from the 1960s & 1970s being sold under the Iso brand.  The Iso name was derived from the company’s pre-war origin in Genoa as a manufacturer of refrigeration units when it was called Isothermos, the construct being iso + thermos, from the Ancient Greek θερμός (thermós) (warm), the implied sense being "something which maintains the correct temperature".  In 2022, the corporate name is IsoRivolta and it continues to operate as a low-volume manufacturer.

The suffix -ic was from the Middle English -ik, from the Old French -ique, from the Latin -icus, from the primitive Indo-European -kos & -ḱos, formed with the i-stem suffix -i- and the adjectival suffix -kos & -ḱos.  The form existed also in the Ancient Greek as -ικός (-ikós), in Sanskrit as -इक (-ika) and the Old Church Slavonic as -ъкъ (-ŭkŭ); a doublet of -y.  In European languages, adding -kos to noun stems carried the meaning "characteristic of, like, typical, pertaining to" while on adjectival stems it acted emphatically; in English it's always been used to form adjectives from nouns with the meaning “of or pertaining to”.  A precise technical use exists in physical chemistry where it's used to denote certain chemical compounds in which a specified chemical element has a higher oxidation number than in the equivalent compound whose name ends in the suffix -ous; (eg sulphuric acid (H₂SO₄) has more oxygen atoms per molecule than sulfurous acid (H₂SO₃).

Norton's isolastic engine mounting

Norton Featherbed frame.

Powerful as the engines were, much of the success in competition Norton’s motorcycles enjoyed in the 1950s were attributable to the “Featherbed” frame, introduced in 1950.  Designed with twin parallel rectangular loops, each formed from a single length of Reynolds steel tubing with crossed-over welded ends which met a securely braced headstock at the front and swinging arm mountings to the rear, the Featherbed frame was stiff, strong and surprisingly light and proved resistant to even sever road and transmission stresses.  It was state of the art but that state reflected the technology of the late 1940s and as the years went by, engine speeds, displacement and compression ratios increased so power and torque rose, imposing mechanical stresses and, most significantly, vibration levels became so pronounced that the big Norton twin-cylinder bikes were becoming less attractive to buyers; while all the power and torque was admired, for many it was rendered unusable by all the shaking which had to be endured at a wide range of engine speeds.

Norton Commando frame.

A new engine was the obvious solution but, despite years of success, by the early 1960s, the whole British motorcycle industry was under-capitalized and nothing emerged; Norton’s bankruptcy surprised few.  Re-structured in 1966 as Norton-Villiers Ltd, it was still obvious a new engine was needed to remain competitive and this was pursued but the engineers suggested a new frame might be a stop-gap solution while engine development proceeded.  Most attractive was that a new frame should cheap and fast to create.  Afforcing the engineering staff, even with a German nuclear physicist who had once worked for Rolls-Royce, work proceeded quickly even though the Featherbed’s box-frame approach was abandoned in favor of a single, large diameter top tube that ran from the top of the steering tube to the seat struts with a short, angled gusset (made from a tube of the same dimension) was incorporated to triangulate the steering/top tube connection.  Two smaller diameter tubes extended from the bottom of the steering tube, running underneath the engine-gearbox unit where, connected by the centre stand’s mounting tube, they curved upwards to meet the seat struts at the rear suspension top fixing brackets.  The frame was completed by a triangulation of the rear section, achieved by using two more tubes which ran from the rear engine-gearbox unit mounting bracket to midway along the large top tube.

As intended, the new frame was light and the torsional strength (the resistance to twisting) was even higher than the engineers’ theoretical calculations had projected.  The design imperatives had been surprisingly simple, a kind of “back to basics” approach which (1) ensured the relation between the front & rear wheels remained constant regardless of the roughness of the surface, and 2) the higher loadings were Imposed only on the straight tubes, the bent portions of the frame are stressed.  Most innovative was the isolastic mounting system for the engine-gearbox unit (which the factory initially dubbed “GlideRide”.  Although essentially an admission the vibrations inherent in big, twin-cylinder engines couldn’t (then) be fixed, they could substantially be isolated to the unit and not transmitted through the frame to the rider.  At the core of the problem was that as a crankshaft rotates, the engine’s centre of gravity describes a heart-shaped path around the crankshaft axis, the engine therefore tending to oscillate around that path.  What the isolastic system did was provide the engine with three suspension points: (1) at the front, (2) at the top-rear of the gearbox and (3) at the cylinder head.  The mountings were large because of the vibration they needed to absorb but with a torsional stiffness provided by a rigidity in the side mountings, the idea being that the engine must be free to move in the plane of the crankshaft but without twisting in the frame.

When the Norton Commando was launched in 1967, the combination of frame and the isolastic engine-gearbox mounting system proved the inherent vibration problem associated with big twins, if not solved, had been artfully concealed.  The early implementations of both the isolastic plumbing and the frame did reveal some weaknesses but these problems quickly were solved and both enjoyed a decade long life, over 60,000 Commandos produced between 1976-1977.  However, the clever improvisation (driven by financial necessity) really just delayed the inevitable as the manufacturers from the Far East had proven their modern, four-cylinder concepts were a better direction for the high performance motorcycle.  In the ten years the Norton Commando was on sale, the Japanese improved their products while the British tinkered at the edges and by the time the last Commando was made, the superiority it once enjoyed in road-holding and handling had evaporated.  The British industry never recovered from the mistakes made during the 1960s and 1970s.

Isolastic-era advertising: The agencies never depicted women riding Norton Commandos but they were a fixture as adornments, usually with lots of blonde hair and a certain expression.  One reason they may not have been suitable to use as riders was the phenomenon known as “helmet hair” (in idiomatic use, the effects of helmet wearing on those with “big hair”), which, upon removing helmet, manifested either as an unintended JBF or a bifurcated look in which the hair above the shoulders was flattened against the scalp while that beneath sat as the wind had determined.  There was also the challenge of kick-starting the big twins, the long-overdue electric-start not installed until 1975.

Targa

Targa (pronounced ta-gah)

(1) A model name trade-marked by Porsche AG in 1966.

(2) In casual use, a generic description of cars with a removable roof panel between the windscreen and a truncated roof structure ahead of the rear window.

1966 (in the context of the Porsche): From the Targa Florio race in Sicily, first run in 1906 and last staged in its classic form in 1973.  In many European languages, targa (or derivatives) existed and most were related to the Proto-Germanic targǭ (edge), from the primitive Indo-European dorg- (edge, seam), from the Old Norse targa (small round shield) and the Old High German zarga (edge, rim).  The modern Italian targa (plate, shingle; name-plate; number plate or license plate; plaque; signboard; target (derived from the rounded oval or rectangle shield used in medieval times)) was ultimately from the Frankish targa (shield).  In the Old English targa (a light shield) was also from the Proto-Germanic targǭ and was cognate with the Old Norse targa and the Old High German zarga (source of the German Zarge); it was the source of the Modern English target.  The Proto-Germanic targǭ dates from the twelfth century and “target” in the sense of “round object to be aimed at in shooting” emerged in the mid eighteenth century and was used originally in archery.  Targa is a noun; the noun plural is targas.

1974 Leyland P76 Targa Florio in Omega Navy, Aspen Green & Nutmeg (without the side graphics).

Although, especially when fitted with the 4.4 litre (269 cubic inch) V8, it was in many ways at least as good as the competition, the Australian designed and built Leyland P76 is remembered as the Antipodean Edsel; a total failure.  It was doomed by poor build quality, indifferent dealer support and the misfortune of being a big (in local terms) car introduced just before the first oil shock hit and the world economy sunk into the severe recession which marked the end of the long, post war boom.  It vanished in 1975, taking with it Leyland Australia but it did have one quixotic moment of glory, setting the fastest time on Special Stage 8 of the 1974 World Cup Rally, run on the Targa Florio circuit in Palermo, Sicily.  The big V8 machine out-paced the rest of the field by several minutes and to mark the rare success, Leyland Australia built 488 "Targa Florio" versions.  Available in Omega Navy, Aspen Green or Nutmeg (a shade of brown which seemed to stalk the 1970s), the special build was mechanically identical to other V8 P76s with automatic transmission but did include a sports steering wheel and aluminium road wheels, both intended for the abortive Force 7, a two-door version which was ungainly but did offer the functionality of a hatchback.  In a typical example of Leyland's mismanagement, the Force 7 was being developed just as the other local manufacturers were in about to drop their big two-doors, demand having evaporated after a brief vogue.  Leyland do however deserve credit for their plans to name the luxury version of the Force 7 the Tour de Force.

Except for those which (usually) stick to numbers or alpha-numeric strings (Mercedes-Benz the classic example), coming up with a name for a car can be a tricky business, especially if someone objects.  In 1972, Ford of England was taken to court by Granada Television after choosing to call their new car a “Granada” though the judge gave the argument short shrift, pointing out (1) it was unlikely anyone would confuse a car with a TV channel and (2) neither the city nor the province of Granada in Spain’s Andalusia region had in 1956 complained when the name was adopted for the channel.  The suit was thrown out and the Ford Granada went on to such success the parent company in the US also used the name.

Spot the difference.  1966 Ford Mustang Fastback (left) and 1966 Ford T5 Fastback (right).

In Cologne, Ford’s German outpost in 1965 had less success when trying to sell the Mustang in the FRG (Federal Republic of Germany, the old West Germany (1949-1990)) because Krupp AG held (until December 31 1979) exclusive rights to the name which it used on a range of heavy trucks including some configured as fire engines.  A Mustang couldn’t be confused with a truck (though some snobby types in France might have suggested otherwise) but Ford’s legal advice was to settle rather than sue so they attempted to buy the rights.  Their offer (a reputed US$10,000) was rebuffed so for years Mustangs in the FRG were sold as the “T5” which was the car’s project name during its development.  Almost identical to the US version but for the badges, it was one of the most popular US cars sold in Europe, aided by the then attractive US$-Deutsche Mark exchange rate and its availability in military PX (Post Exchange) stores, service personnel able to buy at a discount and subsequently have the car shipped back to the US at no cost.

The badges: As they appeared on the early (1964-1966) Mustangs in most of the world (left), the T-5 badge used on early Mustangs sold in Germany (centre) and the (non-hyphenated) T5 used in Germany between 1967 and 1979

Visually, the changes which distinguished a T5 from a Mustang were slight and included (1) wheel covers with a plain black centre. (2) the word “Mustang” being removed from horn ring & gas (petrol) cap and (3) a “T5” badge replacing the “Mustang” script on the flanks.  Other than these cosmetic items, mechanical changes were limited to suspension settings (including adding the shock-tower cross-brace fitted to the Shelby GT350s) to better suit continental roads and the fitting of European-specification lighting.  Curiously, although Ford obviously didn’t make any effort when coming up with the “T5” name, it did for 1965 create a “T-5” badge (part number C5ZZ-6325622A) to replace the “Mustang” script on the front fenders and it was thought necessary later to do a re-design, the new one (part number CZZ-16098C) dropping the hyphen and placing the centred characters vertically.  Apparently content, the new badge was used until 1979 when Krupp’s copyright expired and the Mustang’s badges became global.  As was common, there were also running changes, a dash bezel above the glove box (with the T5 designation) introduced during 1967 and continued the next year while the 1971 range received a new dash emblem which sat in the centre, above the radio and heater controls.  However, anyone driving or sitting in a T5, unless they were an expert in such things or unusually observant, probably wouldn’t have noticed the car was in any way different from a Mustang of that vintage.

Scenes from Rote Sonne (1970, promotional poster, centre): A 1966 Ford T5 (left) and some of the cast (right) with a (circa 1966) Volkswagen Type 1 (Beetle).  Note the jackboots.

Directed by Rudolf Thome (b 1939), the plotline of Rote Sonne revolves around four young Fräuleins (Peggy, Sylvie, Christine & Isolde) who have entered into a mortiferous pact to use their charms to lure men into their grasp as a prelude to murdering them.  Although criticized as an example of the “pornography of violence” the film genuinely did fit into the contemporary feminist narratives of the FRG (Federal Republic of Germany, the old West Germany), a place in which ripples from the street protests which swept Germany in 1968 were still being felt and it was in 1970 the terrorist collective Rote Armee Fraktion (Red Army Faction (RAF)) was formed; In the English-speaking world it’s better (if misleadingly) known as the Baader–Meinhof Gang.

1962 Daimler SP250 (née Dart).

The Daimler SP250 was first shown to the public at the 1959 New York Motor Show and there the problems began.  Aware the sports car was quite a departure from the luxurious but rather staid line-up Daimler had for years offered, the company had chosen the attractively alliterative “Dart” as its name, hoping it would convey the sense of something agile and fast.  Unfortunately, Chrysler’s lawyers were faster still, objecting that they had already registered Dart as the name for a full-sized Dodge so Daimler needed a new name and quickly; the big Dodge would never be confused with the little Daimler but the lawyers insisted.  Imagination apparently exhausted, Daimler’s management also reverted to the engineering project name and thus the car became the SP250 which was innocuous enough even for Chrysler's attorneys.  The Dodge Dart didn't for long stay big, the name in 1964 re-used for a compact line although it was the generation made between 1967-1977 which was most successful and almost immediately Chrysler regretted the decision to cease production, the replacement range (the Dodge Aspen & Plymouth Volaré (1976-1980)) one of the industry's disasters.  The name was revived in 2012 for a new Dodge Dart, a small, front wheel drive (FWD) car which was inoffensive but dreary and lasted only until 2016.  The SP250 was less successful still, not even 3000 made between 1959-1964, something attributable to (1) the unfortunate styling, (2) the antiquated chassis, (3) the lack of development which meant there were basic flaws in the body engineering of the early versions and (4) the lack of interest by Jaguar which in 1960 had purchased Daimler, its interest in the manufacturing capacity acquired rather than the product range.  It was a shame because the SP250's exquisite 2.6 litre (155 cubic inch) V8 deserved better.  

Lindsay Lohan with Porsche 911 Targa 4 (997), West Hollywood, 2008.  The Targa was reportedly leased by her former special friend, DJ Samantha Ronson (b 1977).

Sometimes though, numbers could upset someone.  Even in the highly regulated EEC (European Economic Community, the origin of the European Union (EU)) of the 1960s, a company in most cases probably couldn’t claim exclusive rights to a three number sequence but Peugeot claimed exactly that when Porsche first showed their new 901 in 1963.  Asserting they possessed the sole right to sell in France car with a name constructed with three numbers if the middle digit was a zero, the French requested the Germans rename the thing.  It was the era of Franco-German cooperation and Porsche did just that, announcing the new name would be 911, a machine which went on to great things and sixty years on, remains on sale although, the lineage is obvious, only the odd nut & bolt is interchangeable between the two.  So all was well that ends well even if the French case still seems dubious because Mercedes-Benz had for years been selling in France cars labelled 200 or 300 (and would soon offer the 600). Anyway, this time, it was the project name (901) which was discarded (although it remained as the prefix on part-numbers) and surviving examples of the first 82 cars produced before the name was changed are now highly prized by collectors.

Sometimes however, the industry uses weird names for no obvious reason and some of the cars produced for the JDM (Japanese domestic market) are, to Western ears, truly bizarre though perhaps for a Japanese audience they’re compellingly cool.  Whatever might be the rationale, the Japanese manufacturers have give the world some memorable monikers including (1) from Honda the Vamios Hobio Pro & the That's, (2) from Mazda the Titan Dump, the Scrum Truck & the Bongo Brawny, (3) from Mitsubishi the Super Great, the eK-Classy, the Town Box, the Mirage Dingo Teddy Bear & the Homy Super Long, (4) from Suzuki the Solio Bandit & the Mighty Boy, (5) from Toyota the Royal Lounge Alphard, (6) from Subaru the Touring Bruce, (7) from Nissan the Big Thumb, the Elgrand Highway Star & the Cedric and (8) from Cony, the Guppy.

Compared with that lot, Porsche deciding to call a car a Targa seems quite restrained.  Porsche borrowed the name from Targa Florio, the famous race in the hills of Sicily first run in 1906 and where Porsche in the 1950s had enjoyed some success.  Long, challenging and treacherous, it originally circumnavigated the island but the distance was gradually reduced until it was last run in its classic form in 1973 although in even more truncated form it lingered until 1977.  The construct of the name of the Targa Florio, the race in Italy from which Porsche borrowed the name, was Targa (in the sense of “plate” or “shield” + Florio, a tribute to Vincenzo Florio (1883-1959), a rich Sicilian businessman, automobile enthusiast and scion of a prominent family of industrialists and sportsmen; it was Vincenzo Florio who in 1906 founded the race.  Porsche won the race seven times between between 1963-1970 and took victory in 1973 in a 911 Carrera RSR, the car which in its street-legal (the Carrera RS) form remains among the most coveted of all the 911s and many replicas have been created.  Porsche didn't make any 1973 Carrera RS Targas; all were coupés.

1938 Packard 1605 Super Eight Sedanca de Ville by Barker.

The idea of a vehicle with a removable roof section over the driver is more ancient even than the Porsche 911.  Now, a “town car” is imagined as something small and increasingly powered in some Greta Thunberg (b 2003) approved way but in the US, what was sold as a “Town Car” used to be very big, very thirsty (for fossil fuels) and a prodigious emitter of greenhouse gasses.  The idea had begun in Europe as the coupé de ville, deconstructed as the French coupé (an elliptical form of carosse coupé (cut carriage)) and the past participle of couper (to cut) + de ville (French for “for town”).  So, it was, like the horse-drawn coupé carriage, a smaller conveyance for short-distance travel within cities, often just for two passengers who sat sometimes in an enclosed compartment and sometimes under a canopy while the driver was always exposed to the elements.  In the UK, the style was often advertised as the clarence carriage.  The coach-builders of the inter-war years created naming practices which were not consistent across the industry but did tend to be standardized within individual catalogues.  In the US, reflecting the horse-drawn tradition, the coupé de ville was Anglicized as coupe de ville and appeared as both “town brougham” and “town car”, distinguished by the enclosed passenger compartment (trimmed often in cloth) and the exposed driver who sat on more weather resistant leather upholstery.

1974 Lincoln Continental Town Car.  The big Lincolns of the 1970s are about as remote as can be imagined from the original idea of something small and agile for use in congested cities but Ford also called this body style the "pillared hardtop" so by then, linguistic traditions clearly meant little.

Dating from the 1920s, a variant term was “Sedanca de ville”, briefly used to describe a particular configuration for the roof but so attractive was the word it spread and soon there appeared were Sedancas and Sedanca coupés.  Like many designations in the industry, it soon ceased to carry an exact meaning beyond the front seats being open to the skies although by the 1920s there was usually a detachable or folding (even some sliding metal versions were built) roof and windscreens had become a universal fitting.  For a while, there probably was (unusually in an industry which often paid scant attention to the details of etymology) an understanding a Sedanca de ville was a larger vehicle than a Sedanca coupé but the former term became the more generally applied, always on the basis of the ability of the driver’s compartment to be open although it’s clear many of the vehicles were marketed towards owner-drivers rather than those with chauffeurs, that cohort having moved towards fully enclosed limousines.  It’s from the Sedanca tradition the US industry later picked up the idea of the “town car” although the association was vague and had nothing to do with an open driver’s cockpit; it was understood just as a model designation which somehow implied “prestige”.

1968 Triumph TR5 with “Surrey Top”.

Porsche had since the late 1940s been building roadsters and cabriolets but while the 911 (then known internally as Project 901) was under development, it was clear US regulators, in reaction to a sharply rising death toll on the nation’s highways, were developing some quite rigorous safety standards and a number of proposals had been circulated which threatened to outlaw the traditional convertible.  Thus the approach adopted which, drawing from the company’s experience in building race cars, essentially added a stylized roll-over bar which could accommodate a detachable roof-section over the passengers and a folding rear cover which included a Perspex screen (the solid rear glass would come later).  Actually, the concept wasn’t entirely novel, Triumph introducing something similar on their TR4 roadsters (1961-1967) although their design consisted of (1) a half-hard top with an integral roll-bar & fixed glass rear window and (2) two detachable (metal & vinyl) panels which sat above the passengers.  Customers universally (and still to this day) referred to this arrangement as the “Surrey Top” although Triumph insisted only the vinyl insert and its supporting frame was the “Surrey” while the rest of the parts collectively were the “Hard Top kit”.  The targaesque top was available on the TR5 (1967-1969), a de-tuned version of which was sold in North America as the TR250 with twin carburetors replacing the Lucas mechanical fuel-injection used in most other markets, the more exotic system then unable to comply with the new emission standards.

However, long before Porsche told us there were Targa and a decade before even Triumph’s Surrey, Ford had displayed a two-seat “targa”.  In the years to come, things like the 1953 Ford X-100 would be called “concept cars” but that term didn’t then exist so Ford used the more familiar “dream car” and that does seem a more romantic way of putting it.  Reflecting the optimistic spirit of the early post-war years, the X-100 included a number of innovations including the use of radial-ply tyres, a built-in hydraulic jacking system, a rain-sensor which automatically would trigger an electric motor to close the sliding plexiglass roof panel, a built-in dictaphone, a telephone in the centre console and the convenience of heated seats and an electric shaver mounted in the glove compartment.  Some of the features became mainstream products, some not and while the “variable volume horn” wasn’t picked up by the industry, one did appear on the Mercedes-Benz 600 (W100; 1963-1981) although that was a rare supportive gesture.  It was also an age of imaginative labels and Ford called their quincunx induction system the “Multi-Plex”; while the engineering proved a cul-de-sac, the name did later get picked up by multi-screen suburban cinema complexes.  For the X-100, Ford used what was then a popular technique in the lunatic fringe of the burgeoning hot rod: an induction system using five carburettors in a Quincunx pattern.  Inherent difficulties and advances in engineering meant the fad didn’t last but the apparatus remins pleasing to those with a fondness of unusual aluminium castings and intricate mechanical linkages.  X-100 still exists and is displayed at the Henry Ford Museum in Dearborn, Michigan.

1969 Mercury Marauder X-100.  In 1969, the blacked-out trunk (boot) lid and surrounds really was done by the factory.  During the administration of Richard Nixon (1913-1994; US president 1969-1974), things were not drab and predictable.

In a number of quirky coincidences, the name X-100 seems to once have been an industry favourite because as well as the 1953 Ford “dream car”, it was the US Secret Service’s designation for the 1961 Lincoln Continental parade convertible in which John Kennedy (JFK, 1917–1963; US president 1961-1963) was assassinated in Dallas, Texas.  One might have thought that macabre association might have been enough for the “X-100” tag to not again be used but, presumably because the Secret Service’s internal codes weren’t then general public knowledge, in 1969 Ford’s Mercury division released an X-100 as an up-market version of its second generation (1969-1970) Marauder.  Notionally, the X-100 was a “high performance” version but its 365 (gross) horsepower 429 cubic inch (7.0 litre) V8 was an option in lesser priced Marauders which meant the X-100, weighed down by the additional luxury fittings, was just a little slower than the cheaper models with the 429.  The market for “full-sized” high performance cars was anyway by 1969 in the final stages of terminal decline and although an encouraging 5635 were sold in 1969, sales the next year fell to 2646 and the X-100 was retired at the end of the 1970 and not replaced.  Most bizarre though was project X-100, a US$75 million (then a lot of what was at the time borrowed money) contract in 1943 awarded to Chrysler to design, machine and nickel-plate the inner surfaces of the cylindrical diffusers required to separate uranium isotopes.  Part of the Manhattan Project which built the world’s first atomic bombs, Chrysler built over 3,500 diffusers used at the plant in Oak Ridge, Tennessee and many were still in service as late as the 1980s.  Not until after the first A-bomb was used against Hiroshima in August 1945 did most of the X-100 project’s workers become aware of the use being made of the precision equipment they were producing.

Built by Ferrari: 1973 Dino 246 GTS with "chairs & flares" options.  The "GTS" stood for "Gran Tourismo Spider" but it was a true targa in the sense codified by Porsche.

The rhyming colloquialism “chairs and flares” (C&F to the Ferrari cognoscenti and these days the early Dinos are an accepted part of the family) is a reference to a pair of (separately available) options available on later production Dino 246s.  The options were (1) seats with inserts (sometimes in a contasting color) in the style used on the 365 GTB/4 (Daytona) & (2) wider Campagnolo Elektron wheels (which the factory only ever referred to by size) which necessitated flared wheel-arches.  In the early 1970s the factory wasn’t too punctilious in the keeping of records so it’s not known how many cars were originally built equipped with the wider (7½ x 14” vs 6½ x 14”) wheels but some privately maintained registers exist and on the basis of these it’s believed production was probably between 200-250 cars from a total run of 3569 (2,295 GT coupés & 1,274 GTS spiders (targa)).  They appear to have been most commonly ordered on UK & US market cars (although the numbers for Europe are described as “dubious” and thought an under-estimate; there are also an unknown number in other countries), the breakdown of verified production being:

246 GT: UK=22, Europe=5, US=5.
246 GTS: UK=21, Europe=2, US=91.

The “chairs and flares” cars are those which have both the Elektron option and the Daytona-style seats but because they were available separately, some were built with only one of the two, hence the existence of other slang terms in the Dino world including “Daytona package”, “Sebring spiders” and, in the UK, the brutish “big arches”.  In 1974, the Dino's option list (in US$) comprised:

Power windows: $270.00
Metallic paint: $270.00
Leather upholstery: $450.00
Daytona type central seat panels: $115.00
Air-conditioning: $770.00
14 x 7½ wheels & fender flares: $680.00
AM/FM/SW radio: $315.00
Electric antenna & speakers: $100.00

At a combined US$795.00, the C&F combo has proved a good investment, now adding significantly to the price of the anyway highly collectable Dino.  Although it's hard to estimate the added value because so many other factors influence calculation, all else being equal, the premium would seem to to be well over US$100,000.  Because it involves only wheels, upholstery and metal, the modifications are technically not difficult to emulate although the price of a modified vehicle will not match that of an original although unlike some of the more radical modifications to Ferraris (such as conversions to roadsters), creating a C&F out of a standard 246 seems not to lower its value.  These things are always relative; in 1974 the C&F option added 5.2% to the Dino GTS's list price and was just under a third the cost of a new small (in US terms a "sub-compact") car such as the Chevrolet Vega (1970-1977).

An enduring design: 2023 Porsche 911 Targa 4 (992).

Porsche didn’t complicate things, in 1966 offering the Targa as an alternative to the familiar coupé, then in series production since 1964.  Briefly, the company flirted with calling the car the 911 Flori but ultimately Targa was preferred and the appropriate trademarks were applied for in 1965, the factory apparently discovering targa in Italian means “number plate” or “license plate” only that year when the translators were working on international editions of the sales brochures.  The now familiar fixed, heated rear screen in safety glass was first offered in 1967 as an alternative to the one in fold-down plastic one and such was the demand it soon became the standard fitting.  The Targa carried over into the 911’s second and third generation being, re-designed for 1993 in a way that dispensed with the roll bar and it wouldn’t be until 2011 the familiar shape returned.

1970 Iso Grifo Targa (Series I, 350 cubic inch (5.7 litre) Chevrolet V8, left) and 1971 Iso Grifo Can-Am Targa (Series II, 454 cubic inch (7.4 litre) Chevrolet V8, right).  The raised centre section on the hood (bonnet) of the big-block Grifos was known informally as the "penthouse"; it was required because the induction system sat higher than on the small-block cars.  Not all approved of the penthouse because they found it discordant with the otherwise flowing lines but its brutish functionalism seems a fitting tribute brute force beneath.

Among the small volume manufactures which in the post-war years found a lucrative niche in combining sensuous European coachwork with the cheap, powerful and robust American V8s, there was a focus on two-door coupés because (1) this was the example set by Ferrari and (2) there most demand in the segment clearly existed.  The ecosystem was sent extinct by the first oil shock of the early 1970s but in the era, some did offer convertibles and where not, there were specialists prepared to help.  There was though, the odd targa.  The achingly lovely Iso Grifo spyder (roadster) shown at the Geneva Motor Show in 1964 never reached production but in 1966, less than two years into the Grifo’s life (during which almost 100 had been made), the factory put a targa version on their stand at the Turin Motor Show.  It was only ever available to special order on a POA (price on application) basis and between then and the shuttering of the factory in 1974, only 17 were built, four of which were the Series II Can-Ams with the big-block Chevrolet V8.
