Superbird

Superbird (pronounced soo-per-burd)

(1) A one-year version of the Plymouth Road Runner with certain aerodynamic enhancements, built to fulfil the homologation requirements for use in competition.

(2) A one-off Ford Falcon XA GT built by Ford Australia for the motor show circuit in 1973 (and subsequently a derived (though much toned-down) regular production model offered for a limited time).

1969: The construct was super + bird.  The Middle English super was a re-purposing of the prefix super, from the Latin super, from the Proto-Italic super, from the primitive Indo-European upér (over, above) and cognate with the Ancient Greek ὑπέρ (hupér).  In this context, it was used as an adjective suggesting “excellent quality, better than usual; wonderful; awesome, excellent etc.  Bird was from the Middle English bird & brid, from the Old English bridd (chick, fledgling, chicken).  The origin was a term used of birds that could not fly (chicks, fledglings, chickens) as opposed to the Old English fugol (from which English gained the modern “fowl”) which was the general term for “flying birds”.  From the earlt to mid-fourteenth century, “bird” increasingly supplanted “fowl” as the most common term.  Superbird is a noun; the noun plural is Superbirds and an initial capital is appropriate for all uses because Superbird is a product name.

Of super- and supra-

The super- prefix was a learned borrowing of the Latin super-, the prefix an adaptation of super, from the Proto-Italic super, from the primitive Indo-European upér (over, above) and cognate with the Ancient Greek ὑπέρ (hupér).  It was used to create forms conveying variously (1) an enhanced sense of inclusiveness, (2) beyond, over or upon (the latter notable in anatomy where the a super-something indicates it's "located above"), (3) greater than (in quantity), (4) exceptionally or unusually large, (5) superior in title or status (sometimes clipped to "super"), (6) of greater power or potency, (7) intensely, extremely or exceptional and (8) of supersymmetry (in physics).  The standard antonym was “sub” and the synonyms are listed usually as “on-, en-, epi-, supra-, sur-, ultra- and hyper-” but both “ultra” and “hyper-” have in some applications been used to suggest a quality beyond that implied by the “super-” prefix.  In English, there are more than a thousand words formed with the super- prefix.  The supra- prefix was a learned borrowing from the Latin suprā-, the prefix an adaptation of the preposition suprā, from the Old Latin suprād & superā, from the Proto-Italic superād and cognate with the Umbrian subra.  It was used originally to create forms conveying variously (1) above, over, beyond, (2) greater than; transcending and (3) above, over, on top (in anatomy thus directly synonymous with super) but in modern use supra- tends to be differentiated in that while it can still be used to suggest “an enhanced quality or quantity”, it’s now more common for it to denote physical position or placement in spatial terms.

Superbirds of the northern & southern hemispheres

1969 Dodge Daytona (red) & 1970 Plymouth Road Runner Superbird (blue).

The Plymouth Superbird was a "homologation special" build only for the 1970 model year.  By the mid 1950s, various NASCAR (National Association for Stock Car Auto Racing) competitions had become wildly popular and the factories (sometimes in secret) provided support for the racers.  This had started modestly enough with the supply of parts and technical support but so tied up with prestige did success become that soon some manufacturers established racing departments and, officially and not, ran teams or provided so much financial support some effectively were factory operations.  NASCAR had begun as a "stock" car operation in the literal sense that the first cars used were "showroom stock" with only minimal modifications.  That didn't last long, cheating was soon rife and in the interests of spectacle (ie higher speeds), certain "performance enhancements" were permitted although the rules were always intended to maintain the original spirit of using cars which were "close" to what was in the showroom.  The cheating didn't stop although the teams became more adept in its practice.  One Dodge typified the way manufactures used the homologation rule to effectively game the system.  The homologation rules (having to build and sell a minimum number of a certain model in that specification) had been intended to restrict the use of cars to “volume production” models available to the general public but in 1956 Dodge did a special run of what it called the D-500 (an allusion to the number built to be “legal”).  Finding a loophole in the interpretation of the word “option” the D-500 appeared in the showrooms with a 260-hp V8 and crossed-flag “500” emblems on the hoods (bonnet) and trunk (boot) lids, the model’s Dodge’s high-performance offering for the season.  However there was also the D-500-1 (or DASH-1) option, which made the car essentially a race-ready vehicle and one available as a two-door sedan, hardtop or convertible (the different bodies to ensure eligibility in NASCAR’s various competitions).  The D-500-1 was thought to produce around 285 hp from its special twin-four-barrel-carbureted version of the 315 cubic inch (5.2 litre) but more significant was the inclusion of heavy-duty suspension and braking components.  It was a successful endeavour and triggered both an arms race between the manufacturers and the ongoing battle with the NASCAR regulators who did not wish to see their series transformed into something conested only by specialized racing cars which bore only a superficial resemblance to the “showroom stock”.  By the 2020s, it’s obvious NASCAR surrendered to the inevitable but for decades, the battle raged.

1970 Plymouth Superbird (left) and 1969 Dodge Daytona (right) by Stephen Barlow on DeviantArt.  Despite the visual similarities, the aerodynamic enhancements  differed between the two, the Plymouth's nose-cone less pointed, the rear wing higher and with a greater rake.  

By 1969 the NASCAR  regulators had fine-tuned their rules restricting engine power and mandating a minimum weight so manufacturers resorted to the then less policed field of aerodynamics, ushering what came to be known as the aero-cars.  Dodge made some modifications to their Charger which smoothed the air-flow, labelling it the Charger 500 in a nod to the NASCAR homologation rules which demanded 500 identical models for eligibility.  However, unlike the quite modest modifications which proved so successful for Ford’s Torino Talladega and Mercury’s Cyclone Spoiler, the 500 remained aerodynamically inferior and production ceased after 392 were built.  Dodge solved the problem of the missing 108 needed for homologation purposes by introducing a different "Charger 500" which was just a trim level and nothing to do with competition but, honor apparently satisfied on both sides, NASCAR turned the same blind eye they used when it became clear Ford probably had bent the rules a bit with the Talladega.

Not discouraged by the aerodynamic setback, Dodge recruited engineers from Chrysler's aerospace & missile division (which was being shuttered because the Nixon-era détente had just started and the US & USSR were beginning their arms-reduction programmes) and quickly created the Daytona, adding to the 500 a protruding nosecone and high wing at the rear.  Successful on the track, this time the required 500 really were built, 503 coming of the line.  NASCAR responded by again moving the goalposts, requiring manufacturers to build at least one example of each vehicle for each of their dealers before homologation would be granted, something which typically would demand a run well into four figures.  Plymouth duly complied and for 1970 about 2000 Superbirds (NASCAR acknowledging 1920 although Chrysler insists there were 1,935) were delivered to dealers, an expensive exercise given they were said to be invoiced at below cost.  Now more unhappy than ever, NASCAR lawyered-up and drafted rules rendering the aero-cars uncompetitive and their brief era ended.

The graphic for the original Road Runner (1968, left) and the version used for the Superbird (1970, right).  Both were created under licence from Warner Brothers, like the distinctive "beep-beep" horn sound, the engineering apparently as simple as replacing the aluminium strands in the mechanism with copper windings.  The fee for the name was US$50,000 with the rights to the "beep-beep" invoiced at a further US$10,000.  

So extreme in appearance were the cars they proved at the time sometimes hard to sell and some were converted back to the standard specification by dealers anxious to get them out of the showroom.  Views changed over time and they're now much sought by collectors, the record price known price paid for a Superbird being US$1,650,000 for one of the 135 fitted with the 426 Street Hemi.  Despite the Superbirds having been produced in some four times the quantity of Daytonas, collectors indicate the're essentially interchangeable with the determinates of price (all else being equal) being determined by (1) engine specification (the Hemi-powered models the most desirable followed by the 6-BBL Plymouths (there were no Six-Pack Daytonas built) and then the 4 barrel 440s), (2) transmission (those with a manual gearbox attracting a premium) and (3) the combination of mileage, condition and originality.  Mapped on to that equation is the variable of who happens to be at an auction on any given day, something unpredictable.  That was demonstrated in August 2024 when a highly optioned Daytona in the most desirable configuration achieved US$3.36 million at Mecum’s auction at Monterey, California.

The price was impressive but what attracted the interest of the amateur sociologists was the same Daytona in May 2022 sold for US$1.3 million when offered by Mecum at their auction held at the Indiana State Fairgrounds.  The US$1.3 million was at the time the highest price then paid for a Hemi Daytona (of the 503 Daytonas built, only 70 were fitted with the Hemi and of those, only 22 had the four-speed manual) and the increase in value by some 250% was obviously the result of something other than the inflation rate.  The consensus was that although the internet had made just about all markets inherently global, local factors can still influence both the buyer profile and their behaviour, especially in the hothouse environment of a live auction.  Those who frequent California’s central coast between Los Angeles and San Francisco include a demographic not typically found in the mid-west and among other distinguishing characteristics there are more rich folk, able to spend US$3.36 million on a half-century old car they’ll probably never drive between the purchase and offering again at auction.  That’s how the collector market works, the cars now essentially the same sort of commodity as paintings or other pieces of art.

The Buick Skylark Grand Sport which in 1965 didn't become a Superbird.

Plymouth paid Warner Brothers US$50,000 to licence the Road Runner trademark but “Superbird” was free to use which must have been pleasing, the avian reference an allusion to the big wing at the rear.  Curiously, had Buick a half-decade earlier decided to pursue what seems in retrospect a “sales department thought bubble”, Plymouth would have had to come up with something else because in 1965 Buick did run a one-off advertisement for their new Skylark Grand Sport (the marque’s toe in the muscle car water) with the copy headed “Superbird”.  It may seem strange Buick had been tempted to enter the muscle car business because, by the time Alfred P Sloan’s (1875–1966; president of General Motors (GM) 1923-1937 and Chairman of the Board 1937-1946) had settled down in 1940, Buick was second only to Cadillac in the GM corporate hierarchy with Chevrolet at the bottom, followed by Pontiac and Oldsmobile.  However, the unexpected success the year earlier of Pontiac’s GTO had proved an irresistible temptation: there were profits to be made.  As it was, Cadillac was the only GM division in the era not to sell a muscle car although the 1970 Eldorado was rated at 400 horsepower (hp), a bigger number than many muscle cars although bizarrely, it was FWD (front wheel drive) and has never been thought part of the ecosystem.

1936 Buick Century, debatably the "first muscle car" although in the mid 1930s, although some fanciful names appeared, it's unlikely anyone would have thought of "Road Runner" or "Superbird".

Although the definition of “muscle car” is by some contested (though nobody thinks it encompasses FWD), the one preferred by the purists is: “a big engine from a big, heavy car installed in a smaller, lighter car” and for Buick, the approach really wasn’t novel.  Although in 1936 the improvement in the economy remained patchy (and would soon falter), Buick rang in the changes, re-naming its entire line.  Notably, one newly designated offering was the Century, a revised version of the model 60, created by replacing the 233 cubic inch (3.8 litre) straight eight with the 320 cubic inch (5.2 litre) unit from the longer, heavier Roadmaster.  Putting big engines into small cars was nothing new and during the interwar years some had taken the idea to extremes, using huge aero-engines, but those tended to be one-offs for racing or speed-record attempts.  In Europe, (slightly) larger engines were sometimes substituted and British manufacturers often put six cylinder power-plants where once there had been a four but their quest was usually for smoothness and refinement rather than outright speed and the Century was really the first time a major manufacturer had used the concept in series production and by many it’s acknowledged as the last common ancestor (LCA) of the muscle car.

The model which in 1965 Buick seemingly flirted with promoting as the “Superbird” was the Skylark Grand Sport, built on the corporate intermediate A-Body shared with Chevrolet, Pontiac & Oldsmobile.  In its first season the Grand Sport was an option rather than a model and it used the 401 cubic inch (6.6 litre) Buick “Nailhead” V8 which technically violated GM’s corporate edict placing a 400 cubic inch displacement limit on engines in intermediates but this was “worked around” by “rounding down” to 400 for purposes of documentation and for that there was a precedent; earlier Pontiac’s 336 cubic inch (5.5 litre) V8 contravened another GM rule and PMD solved that problem by claiming the capacity was really 326 (5.3) and, honor apparently satisfied on both sides, it was back to business as usual.  The Grand Sport option proved a success in and by 1967 the package was elevated to a model as the GS 400, Buick’s new big-block engine a genuine 400 cid (there were also small-block Skylark GSs appropriately labelled GS 340 and later GS 350) and on the sales charts it continued to perform well, but, being a Buick, its appearance was more restrained than the muscle cars from the competition (including those from other GM divisions) so it tended to be overshadowed but this changed in 1968 when the “Stage 1” option was introduced as a dealer-installed option.  What this did was r increase power and torque and optomize the delivery of both for quarter-mile (402 m) sprints down drag strips and as a proof-of-concept exercise it must have worked because in 1969 the Stage 1 package appeared on the factory’s official option list.  When tested, it performed (on the drag strip) so well it was obvious the official output numbers were under-stated but thing really clicked the next year when Buick enlarged the V8 to 455 cubic inches (7.5 litre), delivering 510 lb⋅ft (691 N⋅m) of torque, the highest rating in the industry.  It's often claimed Detroit wouldn't top this until the second generation Dodge Viper (ZB I, 2003-2006) debuted with its V10 enlarged to 506 cubic inches (8.3 litres) but the early 472 (1968) & 500 (1970) cubic inch (7.7 & 8.2 litre) Cadillac V8s were rated respectively at 525 lb⋅ft (712 N⋅m) & 550 lb⋅ft (746 N⋅m).

1970 Buick GSX brochure.

Buick in 1970 made available the GSX “Performance and Handling Package” which added a hefty US$1,100 to the GS 455’s base price US$3,098, a factor in it attracting only 678 (presumably most-content) buyers.  The straight-line performance was impressive.  While it couldn’t match the ability of genuine race-bred engines like the Chrysler Street Hemi, Ford Boss 429 or the most lusty of the big-block Chevrolets effortlessly to top 140 mph (225 km/h), on the drag strip, the combination of the prodigious low-speed torque and relatively light weight meant it could be a match for just about anything.  The use of “Stage 1” of course implied there would be at least a “Stage 2” (a la Pontiac’s Ram Air II, III, IV etc) but the world was changing and only a handful of "Stage 2" components were assembled and shipped to dealers.  While both the GSX and Stage 1 would live until 1972, 1970 would be peak Buick.

1967 Dodge Coronet R/T advertisement.

Another footnote to the tale is that in 1967, the year before Plymouth released the Road Runner, Dodge (Plymouth’s corporate stable-mate) published an advertisement for the Coronet R/T (Road/Track) which must have been ticked off by the legal department because cleverly it included the words “road” and “runner” arranged in such as way a viewer would read them as “Road Runner” without them appearing in a form which would attract a C&D (cease & desist letter) from Warner Brothers.  The tie-in obviously with Road/Track was the idea of a runner on the track and the agency must have congratulated themselves but the satisfaction would have been brief because within hours of the advertisement appearing in magazines on newsstands, Chrysler’s corporate marketing division instructed Dodge to “pull the campaign”.  By then, Plymouth’s plans for the surprise release in a few months of the appropriately licensed “Road Runner” were well advanced and they didn’t want any thunder stolen.  The Dodge advertisement remained a one-off but the division must have wished they’d thought of using “Road Runner” themselves because the Super Bee (their take on the Road Runner concept) only ever sold a quarter of the volume of Plymouth’s original; it pays to be first but a flaky name like “Super Bee” can’t have helped.  Subsequently, the names Road Runner & Roadrunner (the latter which, without the initial capital, is the taxonomic term for the bird (genus Geococcyx and known also as chaparral birds or chaparral cocks) Warner Brothers' Wile E. Coyote could never quite catch) have been used for products as varied as a Leyland truck, many sports teams, computer hardware & software and a number of publications.

Australia's Ford Falcon Superbirds 

1973 XA Ford Falcon GT Superbird, built for the show circuit. 

Based on the then-current XA Falcon GT Hardtop, Ford Australia’s original Superbird was a one-off created for display at the 1973 Sydney and Melbourne Motor Shows, the purpose of the thing to distract attention from Holden’s new, four-door Monaro model, a range added after the previous year’s limited production SS had generated sufficient sales for the “proof-of-concept” to be judged a success.  Such tactics are not unusual in commerce and Ford were responding to the Holden’s earlier release of the SS being timed deliberately to steal the thunder expected to be generated by the debut of the Falcon Hardtop.  Although it featured a new "rough-blend" upholstery and a power-steering system with the rim-effort increased from 4 to 8 lbs (1.8 to 3.6 kg), mechanically, the Superbird show car was something of a “parts-bin special” in that it differed from a standard GT Hardtop mostly in the use of some of the components orphaned when the plan run of 250-odd (Phase 4) Falcon GTHOs was cancelled after in 1972 a Sydney tabloid newspaper had stirred a moral panic with one of their typically squalid and untruthful stories about “160 mph (258 km/h) supercars” soon to be available to males ages 17-25 (always a suspect demographic in the eyes of a tabloid editor).  Apparently, it was a “slow news day” so the story got moved from the sports section at the back to the front page where the headline spooked the politicians who demanded the manufacturers not proceed with the limited-production specials which existed only to satisfy the homologation rules for competition.  Resisting for only a few days, the manufacturers complied and within a week the nation’s regulatory body for motor sport announced the end of “series-production” racing and that in future the cars used on the track would no longer need to be so closely related to those available in showrooms.

1973 XA Ford Falcon GT Superbird with model in floral dress.

The Falcon GT Superbird displayed at the motor shows in 1973 however proved something of a harbinger in that it proved a bit of a “trial run” for future ventures in which parts intended solely for racing would be added to a sufficient number of vehicles sold to the public to homologate them for use on the circuits.  In that sense, the mechanical specification of the Superbird previewed some of what would later in the year be supplied (with a surprising amount of car-to-car variability) in RPO83 (regular production option 83) including the GTHO’s suspension settings, a 780 cfm (cubic feet per minute) carburetor, the 15” x 7” aluminium wheels, a 36 (imperial) gallon (164 litre) fuel tank and some of the parts designed for greater durability under extreme (ie on the race track) conditions.  Cognizant of the effect the tabloid press has on politicians, none of the special runs in the immediate aftermath of the 1972 moral panic included anything to increase performance.

Toned down: 1973 Ford Falcon 500 Hardtop with RPO77 (Superbird option pack).

Most who saw the Superbird probably didn’t much dwell on the mechanical intricacies, taken more by the stylized falcon which extended for three-quarters the length of the car.  It was the graphic which no doubt generated publicity in a way the specification sheet never could and it was made available through Ford dealers but the take-up rate was low so which it was decided to capitalize on the success of the show car by releasing a production Superbird (as RPO77), the graphic had been reduced to one about 18 inches (450 mm) in length which was applied to the rear quarters, an ever smaller version appearing on the glovebox lid.  In keeping with that restraint, RPO 77 included only “dress-up” items and a 302 cubic inch (4.9 litre) V8 in the same mild-mannered state of tune as the versions sold to bank managers and such and very different from the high-compression 351 (5.8) in the show car.  Still, RPO 77 did succeed in stimulating interest in the two-door Hardtop, sales of which had proved sluggish after the initial spike in 1972; some 750 were built and that all but 200 were fitted with an automatic transmission was an indication of the target market.  In Australia, the surviving Superbirds are now advertised for six figure sums while the surviving three Phase 4 GTHOs (the fourth was destroyed in a rally which seems an improbable place to use such a thing) can command over a million.  The 1973 show car was repainted from "Pearl Silver" to its original "Wild Violet" before being sold.

Slant

Slant (pronounced slant or slahnt)

(1) A surface, structure, line etc at a slope or in an oblique direction.

(2) In (US) football, an offensive play in which the ball-carrier runs toward the line of scrimmage at an angle (known also as the “slant-in”, a pass pattern in which a receiver cuts diagonally across the middle of the field).

(3) In prosody, as “slant rhyme”, a synonym for the “half rhyme”, “near rhyme” & “quasi-rhyme” (a form of imperfect rhyme in which the final (coda) consonants of stressed syllables (and, in modern English poetry, any following syllables to the end of the words) are identical in sound, but the vowels of the stressed syllables are not.

(4) In typography, a synonym of slash ( / ⟩, particularly in its use to set off pronunciations from other text (not used in IT where the distinctions are between the forward-slash (/) and the back-slash (\) which nerds call respectively the slash and the slosh.

(5) In biology, a sloping surface in a culture medium.

(6) In hydro-carbon extraction, as “slant drilling”, a technique in which the drilling is undertaken at an oblique angle rather than the traditional vertical orientation.

(7) In extractive mining, as type of run in which a heading is driven diagonally between the dip and strike of a coal seam.

(8) In informal use, a glance or look.

(9) To veer or angle away from a given level or line, especially from a horizontal; slope (in to incline, to lean).

(10) Figuratively, to have or be influenced by a subjective point of view, bias, personal feeling or inclination etc (often as “slant towards”, “slanted view” etc); a mental leaning, bias, or distortion (“feminist slant”, “MAGA slant”, “liberal slant”, “business slant” et al).

(11) To cause to slope.

(12) Figuratively, to distort information by rendering it unfaithfully or incompletely, especially in order to reflect a particular viewpoint (more generously sometimes described as “spin” or “massaged”).  The concept is known also as “angle journalism” (the particular mood or vein in which something is written, edited, or published).  In Scots English, the meaning “to lie or exaggerate” captures the flavor.  When used to describe the composing, editing, or publishing of something to attract the interest of a specific sub-group (a “slanted” story), “slanted towards” is necessarily pejorative if used only to suggest something optimized to appeal to a certain market segment or demographic (ie it’s more like “aimed at” or “intended for”).

(13) In slang, as “slant eye” (a racial slur now listed as disparaging & offensive), a reference to people from the Far East (applied historically mostly to the Chinese & Japanese), based on the shape of the eyes.  The variants included “slit eye”, “slitty-eyed” & “slopehead”, all equally offensive and now proscribed.

(14) In painting (art) a pan with a sloped bottom used for holding paintbrushes; a depression on a palette with a sloping bottom for holding and mixing watercolors; a palette or similar container with slants or sloping depressions.

(15) In US regional slang, a sarcastic remark; shade, an indirect mocking insult (archaic).

(16) In US slang, an opportunity, particularly to go somewhere (now rare).

(17) In historic Australian colonial slang, a crime committed for the purpose of being apprehended and transported to a major settlement.

Circa 1480s: From the Middle English –slonte or -slonte, both aphetic (in phonetics, linguistics & prosody, “of, relating to, or formed by aphesis” (the loss of the initial unstressed vowel of a word)) variants of aslant, thought to be of Scandinavian origin.  The other influence was probably the earlier dialectical slent, from the Old Norse or another North Germanic source and cognate with the Old Norse slent, the Swedish slinta (to slip) and the Norwegian slenta (to fall on the side), from the Proto-Germanic slintaną (which, in turn, was probably in some way linked with aslant.  Slant & slanting are nouns, verbs & adjectives, slanted is a verb & adjective, slantish is an adjective, slantwise is an adjective & adverb and slantingly & slantly are adverbs; the noun plural is slants.  The pleasing adjective slantendicular is listed by some as non-standard and presumably is proscribed in geometry and mathematics because it's an oxymoron; it’s a portmanteau word, the construct being slant + (perp)endicular.  It may be useful however in commerce or engineering where it might be used to describe something like a tool with a shaft which at some point assumes an oblique or skewed angle.   So it’s there to be used and slantindicular should be applied to stuff which is neither wholly nor fully slanted and in architecture, such structures are numerous.  In commerce, it could be used as a noun.

The noun slant by the 1650s was used to mean “an oblique direction or plane” and began in geography & civil engineering (of landforms, notably ski-slopes), developed from the verb or its adjective.  The now familiar (in the Fox News sense) meaning “way of regarding something, a mental bias” dates from 1905 while the derogatory slang sense of “a person of Asian appearance” came into use some time in the 1940s, a direct descendent from the earlier "slant-eyes", documented since 1929.  The verb slant is documented since the 1520s in the sense of “obliquely to strike (against something)”, an alteration the late thirteenth century slenten (slip sideways), the origin of which is murky but etymologists have concluded it came (via a Scandinavian source (noting the Swedish slinta (to slip)) and the Norwegian slenta (to fall on one side), from the Proto-Germanic slintanan.  The intransitive sense of “to slope, to lie obliquely” was in use by the 1690s, while the transitive sense of “to give a sloping direction to” had emerged by the early nineteenth century.  As early as the late fifteenth century forms were in use as an adverb, the adjectival use attested from the 1610s.  The technical use in literary theory as “poetic slant rhyme” was first used in the mid 1920s (assonance or consonance) although such lines had appeared for centuries, used sometimes deliberately as a device, sometimes not.  In the following stanza by English poet Peter Redgrove (The Archaeologist, published in Dr Faust's Sea-Spiral Spirit (1972)), the second and third lines contain a form of slant rhyme while the first and fourth have pure rhymes:

So I take one of those thin plates
And fit it to a knuckled other,
Carefully, for it trembles on the edge of powder,
Restore the jaw and find the fangs their mates.

Slanted right: You are watching Fox.

While it’s unlikely volumes of the poetry of Emily Dickinson (1830–1886) sit upon the bookshelves of those members of the Fox News audience who have bookshelves, they likely would concur with her words: “Tell the truth but tell it slant.”  “Slanted reporting” has become something which in recent years has attracted much attention (and much hand-wringing by the usual suspects) as an increasingly polarization of positions has been alleged to be a feature of political discourse in the West.  There is little doubt the effect (as reported) is obvious but there’s some debate about both the mechanics and the implications of the phenomenon.  As long ago as 2018, a study found that although the tenor and volume of things on X (formerly known as Twitter) was found to be increasingly toxic and surging, the number of active users engaged in these political polemics was found to be tiny and their effect was distorted by (1) the huge number of tweets they tended to post, (2) the propensity of their fellow-travelers to re-tweet and (3) the use of bots which were more prolific still.  If anything, recent voting patterns suggest it would seem the views of the general population appear to be trending away from the extremes towards the more centralist positions offered by independents or small-parties, something most obvious in Australia where compulsory voting exists.  Outfits like Fox News offer a slanted take on just about everything (and promote country & western music which truly is inexcusable) but this is something which has been identifiable in the news media as long as it’s existed and their blatant bias is hardly subversive or threatening, simply because it is so blatant.  What was most interesting in what emerged from the recent defamation suit filed by Dominion Voting Systems against Fox News suggested the network’s stance on things was motivated more by the financial imperative than ideological purity.  Intriguingly, what some analysts concluded was that if the universe shifted and the Fox News audience transformed into a bunch of seed-eating hippies, there would follow Fox’s editorial position, the slant being towards the advertising revenue rather than a particular world view.  Of course, there are some slants which are unalterable and dictated by ideological purity but with commercial media, it’s likely sometimes cause is confused with effect.

The New Statesman, 14-20 June 2024: A publication with a leftist slant depicting the European right, slanted to the right.

Founded in 1913 by Sidney (1859–1947) & Beatrice Webb (1858–1943) with patronage from George Bernard Shaw (GBS; 1856-1950) and other worthies from the socialist Fabian Society.  Its circulation was at its highest during the high-water mark of British socialism under Harold Wilson (1916–1995; UK prime minister 1964-1970 & 1974-1976) but, now with print and digital editions in the common manner, it has survived and while unashamedly left-wing (the editorial boards preferring terms like “progressive” & “liberal”), it also has an emphasis on culture and literature, a mix similar to The Spectator (right) and The Economist (centre-right).  Unlike the Spectator which picks up readers from across the spectrum because the often punchy writing attracts (as well as those who read it on the basis of "know thy enemy"), the published surveys suggest The New Statesman's readership tends to be from the left.

The Leaning Tower of Pisa (left) and Lindsay Lohan in The Parent Trap (1998) in front of London’s perpendicular Big Ben (1859) (right).  The architect’s original name for the latter was a typically succinct “Clock Tower”, chosen because it housed the “Great Bell of the Great Clock of Westminster” but it was in 2012 renamed “Elizabeth Tower”, marking the Diamond Jubilee of Elizabeth II (1926-2022; Queen of the UK and other places, 1952-2022), something little noted by Londoners or those beyond who continue to prefer the nickname “Big Ben” although strictly speaking that’s a reference only to the “Great Bell” a 13.5 ton (13.7 tonne) casting in bell metal (a bronze which is an alloy of about 77% copper & 23% tin).  The origin of the nickname is contested but there are no romantic tales, all the possible inspirations being worthy white men as was the Victorian way.

Although in Italy alone there are seven leaning towers (three of which stand (ie lean) in Venice), it’s the torre di Pisa (Tower of Pisa) which is by far the best-known and a frequent Instagram prop.  Built between 1173-1372, the structure in the Piazza del Duomo (Pisa’s Cathedral Square) is the campanile (the freestanding bell tower) of the adjacent Pisa Cathedral and the famous lean of some 4^o (actually somewhat less than its greatest extent after more than a century of compensating engineering works) was apparent even during construction, the cause the softness of the sub-surface.  That geological feature has however contributed to the tower’s survival, the “rubber-like” sponginess below acting to absorb movement and despite a number of severe earthquakes in the region over the centuries, the tower remains.  It is of course known as the leaning tower than a sloping, oblique or slanted tower, probably because of the conventions of use which evolved in English.

The words “sloping”, “oblique”, “slanted”, & “leaning” all describe something not vertical or horizontal there tend to be nuances which dictate the choice of which to use.  Sloping generally is used of something which inclines or declines at a gentle or continuous angle, the implication being of a gradual or smooth transition from elevation to another, such as the way a hillside rises gradually rises to its summit.  Oblique is mostly a matter of specific angles and is thus common is mathematics, geometry and engineering.  Again, it’s a reference to something neither parallel nor perpendicular to a baseline but it tends to be restricted to something which can be defined with an exact measurement; in geometric or technical use, an oblique line or angle is one neither 90^o nor perfectly horizontal.  Slanted describes something positioned at a diagonal, often used to imply a more noticeable or sharp angle but also is widely used figuratively, metaphorically and in idiomatic phrases.  Leaning refers to something tilted or positioned at an angle due to external pressure, the object in an unstable position and in need of support.  The implication carried is that something which “slants” is designed thus to do while something which “leans” does so because of some design flaw or unexpected external force being applied so it’s the leaning and not the sloping tower of Pisa, even though the structure has assumed quite a slope.

Slanting Engines

There are “slant” engines and they exist in three configurations.  The first is simply a conventional in-line engine (straight-six, straight-eight etc) which, when installed in a vehicle, is fitted with the block canted to the left or right, the objective being a lower hood line which means a better aerodynamic outcome.  A classic example was the Mercedes-Benz W196R Formula One racing car (1954-1955) in which the straight-eight was canted to the right at a 53^o angle, the technique carried over when the same structure was used to produce the W196S (1955) used to contest the World Sports Car Championship.  Rather opportunistically, the W196S was dubbed the 300 SLR (one of which in 2022 became the world's most expensive used car, selling at a private auction for US$142 million) as a form of cross promotion with the 300 SL (W198, 1954-1956) Gullwing then in production, even though the two types shared little more than nuts, bolts and a resemblance.  The 300 SL did however also have its straight-six engine sitting at a slant, this time canted at a 50^o angle and although the factory never published an estimate of the reduction in drag, it’s long been presumed to be “at least several percent”.  Another advantage of the configuration was it made possible the use of “long-tube” runners for the induction system, taking advantage of the properties of fluid dynamics to permit them to be tuned either for mid-range torque or top-end power.  The concept used math which had been worked out in the nineteenth century and had often been used in competition but it wasn’t until 1959 when Chrysler in the US released their picturesque induction castings that the system, imaginatively named the “Sonoramic”, reached a wider audience.

Chrysler Slant Six (170 cid, 1963) schematic.

The “true” slant engines were those with a slanted block atop an otherwise conventional arrangement of components, the best known of which was Chrysler’s long-serving “Slant Six”, produced in displacements of 170 cubic inch (2.8 litre, 1959-1969), 198 cubic inch (3.2 litre, 1970-1974) and 225 cubic inch (3.7 litre, 1960-2000).  The block of the Slant Six was canted to the right at a 30^o and like Mercedes-Benz, Chrysler took advantage of the space created to the left to produce some wide induction runners, the most extravagant those used by the special Hyper Pack option package which used a four barrel carburetor, enabling the engine to produce power which made it competitive with many V8 powered machines.  Although the name “Slant Six” became famous, it was only in the mid-sixties it caught on, Plymouth originally calling the thing a 30-D (a reference to the a 30^o slant), hardly very catchy and something to which only engineers would relate and Slant Six was soon preferred although the aficionados really like “tower of power” and the engine even today still has a devoted following.

Chrysler didn’t restrict the Sonoramics to the big-block V8s, using it also on the short-lived (1960-1962) Hyper Pak performance option for the both 170 cubic inch (2.8 litre, 1959-1969) and 225 cubic inch (3.7 litre, 1987-2000) versions of the Slant Six, the engineers taking advantage of the space afforded by the canted block to permit the curvaceous intake runners nearly to fill the engine bay.  The Hyper Pak wasn't seen in showrooms but was available as an over-the-counter kit (literally a cardboard box containing all necessary parts) from Dodge & Plymouth spare parts departments and its life was limited because it became a victim of its own success.  Although less suitable for street use because it turned the mild-mannered straight-six into something at its best at full throttle, in the race events for which it was eligible it proved unbeatable, dominating the competition for two years, compelling the sanctioning body cancel the series.

Manifold porn: The Slant Six's angle meant there was much space available to the left and a range of intake manifolds followed, some of which remain available to this day.  Using variations of the sonoramic tuning, manifolds were produced for single, two & four barrel carburetors and between 1965-1968, Chrysler's Argentine operation produced the Slant Six in a version with twin single barrel carburetors.  The use of the properties of fluid dynamics to gain power or torque as desired quickly was adopted by the industry as an engineering orthodoxy.

Some myths seem to have become attached to the Hyper-Pak.  What seems to be true is the original kit, sold in 1960 for the 170 engines used in competition, was a genuine homologation exercise and as well as the intake manifold & Carter AFB four barrel carburetor, it included all the internal parts such as the high-compression pistons, the high-lift camshaft and the valve train components needed to support the consequently higher engine speeds.  Because the competition rules allowed modifications to the exhaust system, on the track the cars ran tubular steel headers which fed an open exhaust, terminating in the racers' preferred “dump pipe”.  After the requisite number of “complete” kits were sold, thus fulfilling the homologation demands, the kits were reconfigured and included only the “bolt-on” parts such as the induction system and a camshaft which, while more aggressive than the standard unit, wasn’t as radical as the one used on the track but could be used in conjunction with the standard valve train and Chrysler’s TorqueFlite automatic, thus expanding the Hyper-Pak’s appeal.

At the same time, the availability was extended to the larger 225 which between 1961-1963 was also available with an aluminum block, thus becoming one of the small number of engines configured with the combination of an aluminum block with a cast-iron head.  US manufacturers were at the time aware the trend was for cars to continue getting bigger so they were interested in ways to reduce weight.  However, despite saving some 70 lbs (32 KG), Chrysler’s aluminum block was, like General Motors’ (GM) 215 cubic inch (3.5 litre) V8, short-lived (though the V8 after being sold to Rover enjoyed a long, lucrative and prolific second life, not finally laid to rest until 2006) for not only were teething troubles encountered with the still novel method of construction, the accountants made clear using cast iron was always going to be cheaper so the industry just accepted weight gain and whenever required, increased displacement to compensate, an approach which persisted until the first oil shock of the early 1970s.

1970 Dodge Challenger (1970-1974) with 225 Slant Six.

Until 1973, both the Challenger & the corporation's companion E-Body pony car (the Plymouth Barracuda (1969-1974)) was available with the Slant Six (198 & 225) although the fitment rate was under 10%, unlike the early pony cars (Ford Mustang, Chevrolet Camaro and the early Barracudas) where the six-cylinder versions would at times be close to 40% of production.  Many of the surviving Slant Six Challengers & Barracudas have been "re-purposed" as clones of the more desirable versions with potent small or big-block V8s.  Because of the rarity, exceptional examples of slant-six E-body cars do trade in a niche in the collector market. 

Although it was the longer lived 225 version which gained the Slant Six its stellar reputation for durability and the ease with which additional power could be extracted, there's always been a following for the short-stroke 170 because of its European-like willingness to rev, the characteristics of the over-square engine (unique among the slant-six's three displacements (170-198-225)) unusually lively for a US straight-six.  Despite some aspects of the specification being modest (there were only four main bearings although they were the beefy units used in the 426 cubic inch Street Hemi V8), for much of its life it used a tough forged steel crankshaft and high-speed tolerant solid valve lifters; it proved a famously robust engine and one remarkably tolerant of neglect.  Despite that, after the Hyper Pak affair, Chrysler in the US showed little interest in any performance potential, knowing the US preference for V8s, something which doomed also Pontiac's short-lived single overhead camshaft (SOHC) straight-six (1966-1969).  A version of the 225 with a two-barrel carburetor (rated at 160 horsepower, an increase of 15 over the standard unit) was offered in some non-North American markets where V8 sales were not dominant and it proved very popular in South Africa, Australia, New Zealand and Central & South America but only when tighter US emission regulations forced its adoption did a 225 with a two barrel carburetor appear in the home market though there it was installed to restore the power losses suffered after the emission control plumbing was added rather than seek gains.

Pontiac Trophy 4 cutaway.

Making a straight-eight or V8 by combining two in-line fours has been done a few times and many have been successful (although Triumph managed to create a truly horrid one for the otherwise lovely Stag).  Less common is making a four from an eight but that’s what Pontiac did when they conjured their 194.5 cubic inch (3.2 litre) four by using one bank of their 389 cubic inch (6.4 litre) Trophy V8 and it was (just about) literally cut in half, meaning the cylinders were canted to the right by 45^o (the V8 obviously in a conventional 90^o configuration).  To emphasize the family connection with the highly regarded Pontiac Trophy V8, the smaller offspring was called the Trophy 4 (although it was at time also dubbed the Indy 4 or Indianapolis 4 which even at the time sounded ambitious).  It did work and the economic advantages for the manufacturer (use of common components and the same assembly line) were compelling but the limitations inherent in a four-cylinder of such a large displacement were apparent in the rough-running and wear on critical parts and it was available only between 1961-1963 and used in a single model, the compact (in US terms) Tempest.

Pontiac 389 cubic inch V8 and "Tri-Power" (three Rochester two-barrel carburetors) induction in 1966 GTO convertible; one of these is more sought after than two Trophy 4s and worth more than twice as much.

The Pontiac V8 which provided the bones for the Trophy 4 was unusual compared with the US industry's post-war practice in that although its displacement ranged between 265-455 cubic inches (4.3-7.5 litres), only one block was used whereas others would produce several, the most common distinction being the "big block" and "small block", terms which were not always indicative of relative internal capacity but were literal in terms of external dimensions.  Ford muddied the waters a bit when one "big block" was continued in production after another (even bigger) "big block" was released and this had led some to prefer the opportunistically coined "mid block" but that's always been too nerdy for most who continue to prefer the well-understood small-big distinction.  All Oldsmobile's post-war V8s also shared the one basic block but the division followed the usual practice of using a "tall deck" version (ie one with metal added to the casting to permit a longer stroke) for the larger displacement iterations whereas Pontiac chose to use a unique "short deck" casting for some in the last days before General Motors (GM) extended the intra-divisional sharing of engines, something which doomed the Pontiac V8.  The fact that the external dimensions of the Pontiac V8s were almost all identical, regardless of displacement intrigued some who saw a simple, cheap path to power, replacing a 326 cubic inch (5.3 litre) V8 with a 455 cubic inch version a remarkably simple process.  However, as some soon found out, just because it fitted under the hood didn't mean other components would tolerate the increase in power and torque, something which applied especially to some of Pontiac's novel (and short-lived) engineering in the early 1960s such as the flexible driveshaft (the so-called "rope-drive") or the rear-mounted transaxle;  quickly, things would break.

Bigger even than the Pontiac Trophy 4, large displacement four cylinder engines were once common although some were exceptional.  Fiat in 1910 built two of their S76s to contest the world LSR (land speed record) and they were an hefty 28.4 litres (1730 cubic inch), the “Beast of Turin” using its then impressive 290 horsepower (216 kW) to attain a one-way speed of 132.27 mph (213 km/h) but, because it was not possible for the team to make the “return run” (ie in the opposite direction) within the stipulated one hour, the LSR remained with the Blitzen Benz which in 1909 had set a mark of 125.94 mph (202.65 km/h).  On land, never again would anyone build a four with the capacity to match the Beasts of Turin but units with displacements approaching 5.0 litres (305 cubic inch) were not uncommon during the inter-war years.  However, the technology of the internal combustion engine (ICE) greatly advanced during World War II (1939-1945) and one consequence of that was engine speeds rose and less displacement was required for a specific output, both factors which conspired to make the big fours unfashionable.  They did however make a comeback in the 1970s when the clever trick of “balance shafts” enabled the inherently chronic second order harmonic vibrations to be “dampened out” and Porsche between 1991-1995 produced a 3.0 litre (183 cubic inch) range which used the technique.  The balance shaft was invented early in the twentieth century by English engineer Frederick Lanchester (1868–1946) but it was Mitsubishi which in the 1970s patented their “Silent Shaft” system and although Porsche developed their own version, they worked out the Japanese design was superior so used that instead, paying Mitsubishi a small royalty (under US$10) for each one installed.  A balance shaft uses two counterweights (looking something like small hockey pucks with the shaft running through them), set some 1½ inches (40 mm) apart and turns at twice the engine-speed.  With one shaft mounted high on one side of the engine and the other low on the opposite side, the pair counter-rotates, balancing the large reciprocating mass.  In that, the balance shafts can be thought of as a variation of a crankshaft's harmonic balancer.

Headlights on a slant

The one-off, 1938 Jaguar SS100 fixed head coupé (FHC) “Grey Lady” which demonstrates the traditional placement when four lights were used.

Headlights at a slant (mounted diagonally and known also as "canted") have also been a thing.  The inclination designers for decades felt to use a diagonal arrangement for headlights began innocently enough in the pre-war years when it emulated the usual practice of placing a pair of driving lamps or for lights inboard of the main headlamps and lower down, mounted typically on the bumper bar or its supporting brackets.  Most headlamps until the late 1930s were in separate housings, as were the auxiliary devices and even cars which integrated them into the coachwork adopted the same geometry.  This was due in part to the evolutionary nature of automobile styling which has often tried to avoid the “shock of the new” and in part to regulations, especially those which applied in the US.

Jaguar S-Type (1963-1968, left), Vanden Plas Princess R (1964-1968, centre) and Volvo 164 (1968-1975, right).

Although most would regard the technique which essentially integrated the driving lamps/fog lamps into the coachwork as just a variation on the diagonal theme, professional designers insist not; they say this is just wrapping enveloping bodywork around an existing device.  Also, the professionals prefer the term “canted headlamps” because “diagonal” has a more precise definition in mathematics.

Rover 3.5 Coupé (P5B 1967-1973, left) and Packard Coupe (1958) (right)

While the US manufacturers usually re-tooled in 1957-1958 after regulations had been changed to allow quad head-lamps, the British were often fiscally challenged and needed to continue to use existing sheet metal.  A design like the Vanden Plas Princess R (and the companion Wolseley 6/99 & 6/110 (1959-1968)) has sufficient space to allow the diagonal placement but the Rover P5 (1958-1967) with its wider grill precluded the approach so the expedient solution was to go vertical.  Although obviously just “bolted on”, such was the appeal of the P5B it just added to the charm.  It could have been much worse because less charming was the 1958 Packard Coupe, produced by Studebaker-Packard, the company an ultimately doomed marriage of corporate convenience which seemed at the time a good idea but proved anything but. Studebaker-Packard lacked the funds to re-tool to take advantage of the rules allowing four head-lamps but without the feature their cars would have looked even more hopelessly outdated than they anyway did so cheap fibreglass “pods” were produced which looked as “tacked on” as they were.  They were the last Packards made and Studebaker’s demise followed within a decade.

1963 Zunder

The Zunder ("spark" in German) was produced in Argentina between 1960-1963 and used the power-train from the Porsche 356.  The body was fashioned in fibreglass and was one of the many interesting products of the post war industry in Brazil and Argentina, the history of which is much neglected.  By the standards of time, it was well-built but as a niche product, was never able to achieve the critical mass necessary to ensure the company’s survival and production ceased in 1963 after some 200 had been built.

Buick Electra 225 (First generation 1959–1960, left) and (Lincoln) Continental Mark III (1958-1960, right).  The Buick adopted horizontal headlamps in 1960.

In the late 1950s, most US manufacturers did have cash to spend and the industry spirit at the time was never to do in moderation what could be done in excess although by comparison with the Lincoln, the Buick verged on the restrained.  Tellingly, the Buick sold well while the Continental was such a disaster Ford considered sending Lincoln to join Edsel on the corporate scrapheap and the nameplate was saved only because it was possible at low cost to re-purpose a prototype Ford Thunderbird as the new Continental.  Rarely has any replacement been such a transformation and the 1961 Continental would influence the design of full-sized American cars for twenty years.  It used horizontally mounted head-lamps.

1961 Chrysler 300 G.

Chrysler’s “Letter Series 300” (1955-1965) coupes and convertibles were the brightest glint in the golden age in which Detroit’s power race was played out in the big cars, an era which would be ended by the introduction of the intermediates and pony cars in the 1960s.  The 300G (1961) was visually little changed from the previous year’s 300F but the simple change to diagonal headlamps was transformative.  There were those who didn’t like the look but generally it was well received and as a first impression, the feeling might have been Chrysler had mastered the motif in a way the Continental Mark III proved Ford just didn’t get it.

1961 DeSoto Adventurer (left), 1962 Dodge Dart (centre) and 1963 Dodge Polara (right).

However, Chrysler’s designers in the early 1960s may have decided they liked diagonal headlamps which was good but seemingly they liked them so much they though the buyers should be offered as many permutations of the idea as could be made to work on a production line.  What’s remarkable is not that the public didn’t take to the approach but that it took the corporation so long to admit the mistake and try something more conventional.  Just to hedge their bets, while Dodge, Plymouth and DeSoto all had headlamps mounted at an obvious degree of cant, on the Chryslers the effect was so subtle one really needed to hold a spirit level to the front end to confirm there was an slant, albeit one imperceptible to the naked eye.  The one division which never were the diagonal way was the Imperial but it’s headlamp treatment was more bizarre still.

1961 DeSoto styling proposal (September 1958) for the 1961 range.

For DeSoto, things could have looked worse even than they did, some of the implementations of the diagonal motif which went as far as clay models or actual metal prototypes so bizarre one wonders what external influences were being studied (or inhaled).  As it turned out, 1961 would be the end of the line for DeSoto, a nameplate which had been successful as recently as the mid 1950s.  Its demise was little to do with diagonal head-lamps (though they didn’t help) but a product of Chrysler’s other divisions expanding their ranges up and down, encroaching on a market segment DeSoto once found so lucrative.  The phenomenon was a harbinger of the eventual fate of marques like Mercury, Pontiac, Oldsmobile and Plymouth.

Retractable headlights: 1972 Ferrari 356 GTC/4 (top left), 1968 Lamborghini Isoero (top right), 1967 Maserati Ghibli Spyder (bottom left) and 1970 Plymouth Superbird (bottom right).

Although sometimes the diagonal placement of headlights was a deliberate choice by the stylist, it could be something dictated by the body's shape and this was the case when quad units were used in conjunction with retractable housings.  On most cars the diagonal motif appeared with the outboard lights mounted noticeably higher than those inboard but, because of the slope, when retractable lights were used the inner lights could sit higher, the visual effect sometimes exaggerated because the angle the housing (following the horizontal nose-line) assume when erected made the inboard lights seem higher still.  It was a product of shape and not something inherent to the “pop-up” retractable technique: The 1969 Dodge Daytona and 1970 Plymouth Superbird (both homologation exercises for use on the NASCAR (National Association for Stock Car Auto Racing) ovals & tracks) both had their four headlights aligned in the horizontal.

1964 Bentley S3 “Chinese-eye” two-door saloon by Mulliner, Park Ward (MPW).  MPW was in 1961 created as the in-house coach-building division of Rolls-Royce by merging Park Ward (a subsidiary since 1939) and H. J. Mulliner (a subsidiary since 1959).  In 1991 the operation was shut down but the Mulliner name endures as Bentley’s “personal commissioning division” which offers services ranging from high-priced bling to bespoke coach-built bodies.

Bentley’s Continental “sports saloon” was in 1952 introduced on the R-Type chassis, the line continued (with some sacrifice in individuality) with the S-Type generation of six-cylinder cars in 1955.  When the S2 was released in 1959, the external appearance was little changed although under the bonnet (hood) there was the new 6¼ litre V8 which faithfully would serve for some six decades until 2020 when the last was fitted to a Bentley Mulsanne although by then, there were few parts able to be interchanged with those in the original run.  With the debut of the V8, it was no longer possible to purchase a Bentley with a manual transmission and, unlike some of the S3 range, all the Continentals had coach-built bodies from H J Mulliner, James Young or Park Ward.  The Mulliner (and later MPW) cars featured slanting nacelles for the quad headlights and quickly these gained the sobriquet “Chinese eye” which, surprisingly, seems to have survived the linguistic treadmill and the term still is used by the trade servicing the collector community.

Clockwise from top left: Fiat 8V (1952-1954), Gordon-Keeble GK-1 (1961-1967), Jensen C-V8 (1962-1966) and Triumph Vitesse convertible (1962-1971).

Perhaps surprisingly, the French majors were never much enamored, presumably because Citroën and Renault didn’t like to be thought imitative and Peugeot was too conservative.  Some of the Europeans did dabble with the idea, embracing it as an expression of modernity although the then radical treatment of the head-lamps sometimes struck a discordant note when the look was grafted onto something where the rest of the platform was so obviously from one or two generations past.  Fiat’s exquisite 8Vs didn’t all get the diagonal look but those which did remain the most memorable of the few of the breed built.  An unqualified aesthetic success was the Gordon-Keeble built to aviation standards and powered by a Chevrolet V8 in Corvette tune.  It deserved to succeed but floundered as much of the British industry did in the era because of a lack of capitalization and an accounting operation which didn’t match the quality of the engineering.  More commercially successful was the Jensen C-V8 but while the distinctive front end now makes it much prized by collectors, at the time it was less admired and its very presence served only to emphasize how antiquated the rest of the styling had become.  For its replacement, Jensen tuned to an Italian styling house and the Interceptor, introduced in 1966 and remembered for the vast expanse of rear glass, is now thought a classic of the era.  The one which sold best was the Triumph Vitesse, one of a number of variations built on the robust and versatile separate chassis of the Herald (1959-1971) including the Spitfire and GT6.  Although not exactly the BMW M3 of its day, the six-cylinder engines did provide effortless performance and the Vitesse’s front end actually lived on in India (though without the torquey straight-sixes) to enjoy an "Indian summer" but curiously, the inner headlights weren’t fitted.

Gilding the lily: The Lancia Fulvia coupé (1965-1976) before & after.

The lovely, delicate lines of the Lancia Fulvia were perfect and really couldn’t be improved.  The unfortunate facelift with the canted lights was no improvement.
