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 since 1965.

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; the noun plural is penthouses.

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-capacity 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 (b 1926), 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) 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 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 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 the a license was granted.  Powered by tiny two and four-stroke engines, their popularity waned as “real” cars such as the Fiat 500 (1955) and later the Mini (1959) emerged; although costing little more than the bubble cars, they offered more space, performance and practicality.  By the early 1960s, the bubble cars were driven 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 electric propulsion.

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, the 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.  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, 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 Corvette.

1964 Iso Grifo Spider.

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 Corvette 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 year 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.

1970 Iso Grifo Series Two.

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 the electrical system, most necessitated by new regulatory requirements by some European countries 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 351 cubic inch (5.8 litre) 335 series (Cleveland) V8.  In the state of tune chosen by the factory (essentially the same as fellow Italian specialist De Tomaso were using in their mid-engined Pantera), 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 offer 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.  Petrol was, of course, cheap and limitless.  Petrol actually 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 other people’s money (OPM) so fuel consumption wasn’t something often considered.  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 and often a sense of restraint, effectively to use the prodigious power.  Tellingly, the most receptive market for the Grifos, small and big-block, was the Federal Republic of Germany (FRG, the old West Germany) 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.   

1970 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 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.

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, officially, output dropped from 435 horsepower to 390 but, these were gross (SAE) numbers and Detroit’s high-performance engines in this era were rated at something around what a manufacturer thought would be acceptable (all things considered), rather than an absolutely accurate number but the 454 certainly was just a little less potent than the 427 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, that Giugiaro might have done something more in sympathy with its surroundingsCritics more stern would have preferred a curvaceous scoop 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 in October 1973 which made petrol suddenly not only much more expensive but sometimes also scarce and the whole ecosystem of the trans-Atlantic machines became threatened and in little more than a year, Iso was one of the many dinosaurs driven extinct.  Decades later, the survivors of the 412 sold are highly desirable; fine examples of the small-block Grifos attract over US$500,000, the few dozen penthouse cars can sell for up to a million and the rare early A3/Cs for well over.

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.  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 although the big-block cars hadn't been built in Italy since 1972.  A further complication was that during 1974, Ford had discontinued production of the high-performance 351 (the "Cleveland" 335 series) 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 Cleveland 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$150,000 in 2024 $ although direct translation of such a value is difficult to calculate because of the influence of exchange rates), 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- is 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 et al); 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 et al) 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 (morph) (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 & -os, formed with the i-stem suffix -i- and the adjectival suffix -kos & -os.  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 (HSO) has more oxygen atoms per molecule than sulfurous acid (HSO).

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.

1972 Norton Commando 750 Combat.

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.

Bulge

Bulge (pronounced buhlj)

(1) A rounded projection, bend or protruding part; protuberance; hump; to swell or bend outward; to be protuberant.

(2) Any sudden increase, as of numbers, often used in economics or demography.

(3) In the maritime sciences, a rising in small waves on the surface of a body of water, caused by the action of a fish or fishes in pursuit of food underwater.

(4) As bulging, to describe a box or similar container, the shape of which is distorted by being filled beyond its nominal capacity.

(5) In colloquial use, the outline of male genitals visible through clothing, a form especially popular in the states & micro-states of Melanesia and used also (by analogy with the bulge caused by a wallet) as a descriptor of wealth.

1200-1250: From the Middle English bulge (leather bag; hump), from the Old Northern French boulge & bouge (leather bag), from the Late Latin bulga (leather sack), from the Gaulish bulga & bulgos, from the Proto-Celtic bolgos (sack, bag, stomach).  It was cognate with the various English forms bilge, belly, bellows & budget, the French bouge, the Irish bolg (bag) and the German Balg; a doublet of budge.  Ultimate source was the primitive Indo-European bhelgh (to swell), an extended form of the root bhel (to blow, swell).  The sense of "a swelling, a rounded protuberance" is first recorded in the 1620s and it’s likely the later bilge is a nautical variant.  The later, more familiar military meaning "bulging part of a military front" was first noted in 1916, the Admiralty variation to refer to the shape a warship’s hull assumed after the addition of anti-torpedo armor appearing in the records of naval architects a year later.  The famous phrase "battle of the bulge" has been re-purposed by the weight-loss industry.  Synonyms and related words include wart, lump, nodule, protrude, swell, sag, bloat, projection, bump, swelling, promontory, growth, excrescence, dilation, bunch, protrusion, salient, hump, sac & blob.  Bulge, bulger & bulginess are nouns, bulging & bulgy are adjectives, bulged is a verb and bulgingly is an adverb; the noun plural is bulges.

Increasing bulginess: Lindsay Lohan's baby bump.  English phrases emerge organically and women seem much to prefer "baby bump" to "baby bulge", a Google search for the former returning 33,300,000 hits against a mere 35,000 for the latter.  "Baby bulge" does however have (usually unwanted) role in the process, the "postpartum baby bulge" a description of an abdomen which stubbornly resists post-delivery inducements to return to it's pre-pregnancy shape.

The hood (bonnet) bulge

1957 Jaguar XKSS (left), 1955 Mercedes-Benz 300 SLR (W196S) Uhlenhaut coupé) (centre) and Mercedes-Benz 300 SL (W198, 1954-1963, right).

A hood (bonnet) bulge differs from a hood scoop in that the former exists purely for the purpose of providing clearance for some piece of machinery beneath.  What needs to be accommodated typically will be an inconveniently tall part of the engine, a supercharger or some other component in the induction system.  Jaguar added a bulge to the D-Type (1954-1957) because after lowering the profile of the hood in the quest for aerodynamic efficiency, the XK-six wouldn't quite fit, even with the addition of a dry sump which gained a few inches.  The bulge was carried over to the XKSS, the road-going version of the D-Type.  On the Jaguars, the bulge was centrally placed but Mercedes-Benz, adopting the same expedient for the 300 SLRs needed theirs to exist on only one side where it also acted as an air-intake for the mechanical fuel-injection, an example of a bulge doing also some scooping.  Asymmetry is common on racing cars where function rules but the factory apparently couldn't in those days bring themselves to do it on road cars.  Although the 300 SLs (both the gullwings and the roadsters) needed only the bulge on the right-hard side (the tall, dry-sumped engine canted 50o to the left) to accommodate the fuel-injection's ram-tubes, a matching bulge was included, thus ensuring the symmetry prized by the Germans.

MG MGC-GT (1967-1969, left), Iso-Grifo Can-Am (1968-1972, centre) and Ford Falcon BA XR8 (2002-2004, right).

Mercedes-Benz may have been disturbed by asymmetry but it didn't worry the pragmatists at MG who, having shoe-horned into the MGB (1962-1980) a big iron lump of a straight-six which necessitated using a torsion bar arrangement for the front suspension, found even their first attempt at a bulge still wasn't enough.  A dry sump would have solved the problem but that would have been expensive so a "blister" was added at the offending point on the bulge; a bulging bulge as it were.  Apparently a matching blister on the right was never considered and the MGC has one of the industry's more admired bonnets although that feeling didn't extend to the rest of the car, the model not even a modest success in the market and it lasted but two seasons.  The later V8 version (1973-1976) was both a better car and one that needed no bulge at all but it fell victim to the first oil shock.  There are those who claim the rectilinear protrusion on the hood of the big-block Iso Grifos can't be called a bulge at all and many etymologists might agree but such pedantry should be agreed with and ignored.  Nicknamed the "penthouse", the neo-brutalist construction is one of the industry's great bulges and it's entirely functional, affording clearance to the induction system and providing airflow, in & out.  Not functional at all was the bulge Ford in Australia added to the XR8 Falcons when the BA model was released in 2002.  Cheerfully admitting it was unnecessary and there just for looks, the factory later took advantage of its presence to advertise things like the V8's power output, a juvenile pleasure much appreciated by the target market.

Battle of the Bulge, Dec 1944-Jan 1945

The Ardennes Offensive, (Wacht am Rhein (Watch on the Rhine) was the German code-name) popularly known in the West as the Battle of the Bulge, was the last major German strategic offensive of World War II and ironically, Watch on the Rhine was the title of a play by Lillian Hellman (1905-1984) which debuted on Broadway in 1941, the theme being the need for an international alliance to oppose the Nazis.  After many delays, it began on 16 December 1944 and lasted officially until 25 January but had been repulsed by Allied forces weeks earlier.  It wasn't the first use of "bulge" in a battlefield context, the phrase documented in June 1940 in discussions about the German offensive in France and many generals over the centuries would have seen bulges represented on their situation maps.  One especially well-known One of the best known was Unternehmen Zitadelle (Operation Citadel), the German operation conducted in July 1943 against Soviet forces in the Kursk salient although, unlike the Ardennes Offensive, the Battle of Kursk was staged along a very long front and is best understood as a series of shifting bulges and the theatre evolved rapidly into a huge, dusty, swirling mass of tanks, artillery assaults and air attacks.  It remains history's largest tank battle.  

The bulge, December 1944.

Because of the disparity in military and economic strength between the German and Allied forces, in retrospect, the Ardennes Offensive appears nonsensical but, at the time, it made strategic and political sense.  Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945) knew, confronted as he was by attacks from the west, east and south, continuing to fight a defensive war could only delay the inevitable defeat.  An offensive in the east was impossible because of the strength of the Red Army and even a major battlefield victor in the south would have no strategic significance so it was only in the west that opportunities existed.

For many reasons, by late 1944 the Allied advance in the west had stalled after remarkable progress since the D-Day landings 6 June 1944) and defensive lines had been formed, the most lightly defended being those in the Ardennes Forest, the very region which had been the conduit for the German’s stunningly successful blitzkrieg campaign in 1940.  Despite that history, 1944’s rapid advance through collapsing German lines had convinced Allied intelligence their enemy was no longer capable of major offensive operations.  It was this compliancy which made the German attack possible and in military colleges this problem, created by what in the psychology literature is called "Bayesian perception" (from the probability theories developed by English statistician Thomas Bayes (circa 1700-1761)), is often more helpfully described as "top-down processing" which tends to overwhelm the inherently more accurate "bottom-up processing".  The idea is that a "Bayesian brain" will use prior knowledge and assumptions which will influence perceptions meaning we see what we expect to see and fail to observe what is not expected and the more intensely something is focused upon, the more acute becomes the tendency.  Thus, because the phrase "Paris in the spring" is so well known, a single glance will confirm the brain's perception and the duplicate "the" will remain unseen.

In the last great example of the professionalism and tactical improvisation which was a hallmark of their operations during the war, the Wehrmacht (the German military) secretly assembled a large armored force, essentially under the eyes of the Allies and staged a surprise attack through the Ardennes, aided immeasurably by the cover of heavy, low clouds which precluded both Allied reconnaissance and deployment of their overwhelming strength in air-power.  Hitler’s audacious strategic objective, which, given the forces available, none of his generals though possible, was to advance to the Belgium port of Antwerp, splitting the Allied lines in a pincer movement, destroying their four armies.  This he hoped would force the Western Allies out of the war, permitting the Germans to focus their entire strength against the Soviet Union in the east.

Initially successful, the Wehrmacht’s advance punched several holes in the line, the shape of which, when marked on a map, lent the campaign the name Battle of the Bulge.  Within days however, the weather cleared and the Allies were able to unleash almost unopposed their overwhelming superiority in air power.  This, combined with their vast military and logistical resources, doomed the Ardennes Offensive, inflicting losses from which the Wehrmacht never recovered.  From mid-January on, German forces never regained the initiative, retreating on all fronts until the inevitable defeat in May.

The IDF, Hamas and the Hezbollah, October 2023

Mr Netanyahu.  His friends, (both of them) call him "Bibi".

Already, comparisons with 1944 are being made with the apparent failure of the much vaunted Israeli intelligence machine, either to detect or act upon indications of the activities which would have been a prelude to the audacious attacks launched on 7 October 2023 by the Hamas into Israeli territory.  Although low-tech by comparison with a conventional military operation, the scale of what the Hamas managed to stage would still have demanded movements of materiel and personnel, an exercise in logistics which should have been noticed.  In an echo of the Yom Kippur War (6-25 October 1973), presumably, some activity would have been noticed but clearly it wasn't interpreted as an imminent threat so the inevitable review will have to focus on both the gathering and analysis of intelligence and one thing which will be considered is whether, as in the winter of 1944, assumptions were allowed to prevail over facts on the ground.  Any inquiry can be expected to be rigorous but only within the terms of reference the government will provide and those parameters are unlikely to allow any consideration of the consequences of the recent actions of Benjamin Netanyahu (b 1949; Israeli prime minister 1996-1999, 2009-2021 and since 2022).  Mr Netanyahu has for some time been attempting to make structural changes to Israel's courts, allegedly because he wishes to avoid any judicial scrutiny of the corruption charges which he faces.  The proposed changes to the courts are would actually align the way things are done in Israel with those used in many Western, democratic nations but it's the political context which has made them controversial and part of the widespread and long-lasting public protest has included large numbers of military reservists (on which the security of the Jewish state depends) refusing to serve while the government continues the legal manoeuvres which would have the effect of shielding the prime minister from prosecution.  Mr Netanyahu is one of the great survivors of modern politics and his longevity in office has been a remarkable achievement in one of the world's more difficult neighborhoods but it's unpredictable whether he can turn the shock of the Hamas incursion to his advantage and that is likely to depend upon managing any perception his being distracted by his own legal difficulties made Israel unusually vulnerable.

Securing any advantage will of course depend on Israel gaining what can be presented as a victory, something which in recent conflicts, north & south, has been as elusive on the battlefield as on social media.  Nor is the Hamas attack the only thing which will absorb the resources of the Israeli Defense Force (IDF).  In the north, there is the even more formidable Hezbollah and few in the intelligence community have cast doubt on reports the Shi'ite militia (which out-guns the armed forces of Lebanon and has more political influence) have some hundred-thousand short & medium range rockets available for deployment south of the Litani River (the Qasimiyeh or River Leontes).  Within hours of the Sunni Hamas launching their operation, the Hezbollah targeted Israeli military positions in the disputed Shebaa Farms, announcing it was acting "in solidarity" with the Palestinian people and in response, the IDF responded with artillery barrages.  No casualties were reported and at this stage the attack in the north seems to be thought a supportive gesture rather than anything strategic and the consensus is the Hezbollah will act at scale only if the situation in Gaza evolved to offer a particularly attractive opportunity and even then it would require approval from Tehran; in an unsubtle waring directed at the Ayatollahs, the Pentagon announced the movement of an aircraft carrier into the region.  The Hamas have seemingly timed their high-risk attack with some thought.  With the war in Ukraine demanding much military, political and financial support from the West (something already beginning to fray as Moscow predicted it would in any battle of attrition), the US government in political & fiscal paralysis and Israeli support for its own government at a historic low, the Hamas will have sniffed blood.  Nor will they be unaware the most long-lasting legacy of the Yom Kippur War fifty years earlier was the Arab oil embargo and the spike in the price which ended the long post-war prosperity in the West and triggered the political and economic upheavals which would last a decade.  The structure of the world economy and the imperatives of governments are not in 2023 quite what they were in 1973 but these things will be on the minds of many in many places.

In the short term, within the Israeli intelligence establishment, there will be an admission the military specialists will have to share more of the space with the political analysts.  With a death toll on both sides already in the thousands, the focus is of course on bullets and bombs but what Hamas has also done is stake their claim for support (1) in the region, (2) among the Arab & Palestinian diaspora and (3) from those governments willing to fund proxies for their campaigns against the West.  In this sense, the Hamas is advertising themselves as a muscular resistance to Israeli (ie Western) oppression and occupation, contrasting themselves with Fatah, the faction controlling the Palestinian Authority which exercises nominal authority over what is left of the Left Bank territories.  The Hamas regard Fatah as as least accommodative while some use the slur "collaborators".  Thus positioning the contrast as something like the Marquis vs Vichy, October's assault has a political aspect and in that they identified their target market rather as the Republican Party's "House Freedom Caucus" focused on those dissatisfied with the direction of their own leadership.

What Hamas are practicing is politics with a high civilian death toll, the rationale for that being every Palestinian who is killed will have died a martyr's death with all that implies, theologically and socially.  As a tactic, what Hamas are doing is a kind of political intervention into what they see as the increasingly disturbing trend of Arab nations moving towards normalization of relations with the state of Israel without any settlement of the "Palestinian problem".  If the IDF can be induced to respond with such severity that the civilian death toll in Gaza rises to the point where the pressure from the so called "Arab street" is of such intensity that Arab states are forced to retreat from their recent rapprochements, for Hamas, that would be progress.  There was a time when the strategists in Gaza might have imagined the regional reaction would be something more tangible on the ground but as they've noticed, winds of change can blow in both directions and now it's only in Tehran there's much support for their long-standing position that the only final solution for the Palestinians is the destruction of the state of Israel.
