Fastback

Fastback (pronounced fast-bak or fahst-bak)

(1) A form of rearward coachwork for an automobile body consisting classically of a single, unbroken convex curve from the top to the rear bumper line (there are variations of this also called fastbacks).

(2) A car having using such styling (also used as a model name by both car and motorcycle manufacturers).

(3) A type of pig developed from the landrace or large white and bred for lean meat.

(4) In computing, a product-name sometimes used for backup software.

1960–1965: The construct was fast + back.  Fast was from the Middle English fast & fest, from the Old English fæst (firmly fixed, steadfast, constant; secure; enclosed, watertight; strong, fortified), from the Proto-West Germanic fast, from the Proto-Germanic fastu & fastuz (firm) (which was the source also of the Old Frisian fest, the Old Norse fastr, the Dutch vast and the German fest), from the primitive Indo-European root past- (firm, solid), the source for the Sanskrit pastyam (dwelling place).  The original meaning of course persists but the sense development to “rapid, speedy” dates from the 1550s and appears to have happened first in the adverb and then transferred to the adjective.  The original sense of “secure; firm” is now restricted to uses such as “hard & fast” description of track conditions in horse racing but the derived form “fasten” (attach to; make secure) remains common.  Back was from the Middle English bak, from the Old English bæc, from the Proto-West Germanic bak, from the Proto-Germanic bakam & baką which may be related to the primitive Indo-European beg- (to bend).  In other European languages there was also the Middle Low German bak (back), from the Old Saxon bak, the West Frisian bekling (chair back), the Old High German bah and the Swedish and Norwegian bak; there are no documented connections outside the Germanic and in other modern Germanic languages the cognates mostly have been ousted in this sense by words akin to Modern English ridge such as Danish ryg and the German Rücken.  At one time, many Indo-European languages may have distinguished the horizontal back of an animal or geographic formation such as a mountain range from the upright back of a human while in some cases a modern word for "back" may come from a word related to “spine” such as the Italian schiena or Russian spina or “shoulder”, the examples including the Spanish espalda & Polish plecy.  Fastback is a noun; the noun plural is fastbacks.

Although it was in the 1960s the fastback became a marketing term as the range of models proliferated, it was then nothing new, the lines appearing on vehicles even before 1920, some of which even used the teardrop shape which wind tunnels would confirm was close to optimal, as least in terms of reducing drag although it would be decades before the science evolved to the point where the importance of the trade-off between drag and down-force was completely understood.  To some extent this was explained by (1) so many of the early examples being drawn from aviation where shapes were rendered to optimize the twin goals of reducing drag & increasing lift and (2) road vehicles generally not being capable of achieving the velocities at which the lack of down-force induced instability to a dangerous extent.  Rapidly that would change but there was quite a death toll as the lessons were learned.  By the 1930s, streamlining had become one of the motifs of the high-performance machinery of the era, something coincidently suited to the art deco moment through which the world was passing and in both Europe and the US there were some remarkable, sleek creations.  There was also market resistance.  Chrysler’s engineers actually built one of their sedans to operate backwards and ran tests which confirmed that in real-world conditions the results reflected exactly what the wind-tunnel had suggested: it was quicker, faster and more economical if driven with the rear bodywork facing the front.  Those findings resulted in the release of the Airflow range (1934-1937) and while the benefits promised were realized, the frontal styling proved to be too radical for the time and commercial failure ensued.  People however seemed to like the fastback approach (then often called “torpedo style”) and manufacturers added many to their ranges during the 1940s and 1950s.

Ford Galaxies, Daytona, 1963 (top), 1966 Dodge Charger (bottom left), 1968 Plymouth Barracuda (bottom centre) and 1971 Ford Torino (bottom right).

Ford in 1962 inadvertently provided a case study of relative specific efficiencies of rooflines. The sleek Starliner roof on the 1961 Galaxies used in NASCAR racing sliced gracefully through the air and while sales were initially strong, demand soon slowed and the marketing department compelled a switch to the “formal roofline” introduced on the Thunderbird; it was a success in the showroom but less than stellar on the circuits, the buffering induced by the steep rear windows reducing both stability and speed.  Not deterred, Ford resorted to the long NASCAR tradition of cheating, fabricating a handful of fibreglass hard-tops which would (for racing purposes) turn a convertible Galaxie into a Starliner.  Unfortunately, to be homologated for competition, such parts had to be produced in at least the hundreds and be available for general sale.  Not fooled by Ford’s mock-up brochure, NASCAR banned the plastic roof and not until 1963 when a “fastback” roofline was added was the car’s competitiveness restored.  Actually, it wasn’t really a fastback at all because full-sized cars like the Galaxie had become so long that even a partial sweep from the windscreen to the rear bumper would create absurd proportion but the simple expedient of a sharply raked rear window turned out to work about as well.  Even on intermediates like the Dodge Charger and Ford Torino the pure fastback didn’t really work, the result just too slab-sided.  The classic implementation was when it was used for the shorter pony cars such as the Plymouth Barracuda and Ford Mustang.

The fastback for a while even influenced roofs not fast.  The original Mustang coupé (1964) was a classic “notchback” but such was the impact in the market that later in the year a fastback was added, joining the convertible to make a three body-style range.  The fastback’s popularity was bolstered by Carroll Shelby (1923–2012) choosing that style for his Shelby Mustangs which over the course of half a decade would evolve (or devolve depending on one’s view) from racing cars with number plates to Mustangs with bling but it would also influence the shape of the coupé.  By 1971 the fastback Mustangs (by then called “SportRoofs”) had adopted an even more severe angle at the rear which was dramatic to look at but hard to look through if inside, the almost horizontal rear window restricting visibility which made the more upright coupé (marketed as “Hardtop”) a more practical (and safer) choice.  However, such was the appeal of the fastback look that the profile was fastbackesque, achieved by the use of small trailing buttresses which made their own contribution to restricting reward visibility although not to the extent of some, like Ferrari’s Dino 246 which in some jurisdictions was banned from sale for just that reason.

American Motors Corporation was (until the arrival of Tesla), the “last of the independents” (ie not part of General Motors (GM), Ford or Chrysler) and at its most successful when filling utilitarian niches the majors neglected, their problem being their successes were noticed and competition soon flooded the segments they’d profitably created.  As a result, they were compelled to compete across a wider range and while always a struggle, they did for decades survive by being imaginative and offering packages which, on cost breakdown could be compelling (at one point they joined Rolls-Royce as the only company to offer sedans with air-conditioning fitted as standard equipment).  Sometimes though they got it wrong, and that they did with the Marlin, introduced in 1965 as a fastback based on their intermediate Rambler Classic.  Although the fastback was all about style, AMC couldn’t forget their history of putting a premium on practicality an accordingly, the roof-line grafted on to the classic also ensured comfortable headroom for the rear-seat passengers, resulting in a most ungainly shape.  Sales were dismal for two seasons but AMC persisted, in 1967 switching the fastback to the full-sized Ambassador line which all conceded was better though that was damning with faint praise.  More successful was the Javelin (1968), AMC’s venture into the then lucrative pony-car business which the Mustang had first defined and then dominated.  The early Javelins were an accomplished design, almost Italianate in the delicacy of their lines and the fastback was nicely balanced.  Less balanced but more intriguing was the AMX, a two seat “sports car” created in the cheapest way possible: shorten the Javelin’s wheelbase by 12 inches (300 mm) and remove the rear seat.  That certainly solved the problem of rear seat headroom and over three seasons the AMX received a generally positive response from the press but sales never reached expectations, even a pink one being chosen as the car presented to Playboy magazine's 1968 Playmate of the Year not enough to ensure survival and when the Javelin was restyled for 1971, the two seat variant wasn’t continued although AMX was retained as a name for certain models.  The new Javelins lacked the subtlety of line of the original and the fastback part was probably the best part of the package, much of the rest rather overwrought.  The pony car ecosystem declined in the early 1970s and Javelin production ceased in 1974 although it did by a few months outlive what was technically the first pony-car of them all, the Plymouth Barracuda.

1969 Norton Commando Fastback.

The Norton Commando was produced between 1968-1977.  All Commandos initially used the distinctive tail section which, like the fuel tank, was made of fibreglass and the slope of the molding instantly attracted the nickname “fastback”, an allusion to the body-style then becoming popular for sports cars.  It was the first British motorcycle built in volume of “modern” appearance but, apart from the odd clever improvisation, much of the engineering was antiquated and a generation or more behind the coming Japanese onslaught which would doom the local industry.  In 1969, as other models were added to the Commando range, all of which used more conventional rear styling, the factory formally adopted Fastback as a model name for the originals which remained in production, upgraded in 1970 (as the Fastback Mark ll), fitted with much admired upswept exhausts.  With minor changes, after only four months, it was replaced with the Mark III which served until 1972 when the Mark IV was released, the most notable change being the fitting of a front disk brake.

1970 Norton Commando Fastback (with retro-fitted disk brake).

One interesting variant was the Fastback Long Range (LR) which, although in production for almost two years during 1971-1972, only around 400 were built, most apparently exported to Australia where the distance between gas (petrol) stations was often greater than in Europe or the US.  Although there were other detail differences, the main distinguishing feature of the LR was the larger capacity (in the style of the earlier Norton Atlas) petrol tank, a harbinger of the “Commando Interstate” which became a regular production in 1972 and lasted until Commando production ceased in 1977 by which time it constituted the bulk of sales.  Fastback production ended in 1973 and although some were fitted with the doomed 750 “Combat” engine, none ever received the enlarged unit introduced that year in the Commando 850.

Impressed by Ferrari’s “breadvan”, Ford, this time with the help of a wind-tunnel, adopted the concept when seeking to improve the aerodynamics of the GT40.  Testing the J-Car proved the design delivered increased speed but the resultant lack of down-force proved lethal so the by then conventional fastback body was used instead and it proved successful in the single season it was allowed to run before rule changes outlawed the big engines.

The Europeans took to the fastback style, not only for Ferraris & Maseratis but also to add some flair (and profit margin) to low-cost economy vehicles.  It produced some rather stubby cars but generally they were aesthetically successful and the Skoda 110 R (from Czechoslovakia and thus the Warsaw Pact’s contribution to the fastback school of thought) lasted from 1973-1980 and as the highly modified 130 RS gained an improbable victory in the 1981 European Touring Car Championship against a star-studded field which included BMW 635s, Ford’s RS Capris & Escorts, Audi GTEs, Chevrolet Camaros and Alfa Romeo GTVs.  It was a shame comrade Stalin didn’t live to see it.  Generally, the Europeans were good at fastbacks but the British had some unfortunate moments.  In fastback form, the appearance of the Morris Marina was from the start compromised by the use of the sedan’s front doors which meant the thing was fundamentally ill-proportioned, something which might have been forgiven if it had offered the practicality of a hatchback instead of a conventional trunk (boot).  A dull and uninspiring machine (albeit one which sold well), the Marina actually looked best as a station wagon, an opinion many hold also of its corporate companion the Austin Allegro although the two frequently contest the title of Britain’s worst car of the 1970s (and it's a crowded field).  Even Ford of England which at the time was selling the well-styled fastback Capri had a misstep when it offered the ungainly fastback Granada, many made to look worse still by the addition of the then fashionable vinyl roof, the mistake not repeated when the range was revised without a fastback model.  Compounding the error on an even grander scale however was coach-builder Coleman-Milne which, bizarrely, grafted the fastback’s rear on to a stretched Granada sedan to create what was at the time the world’s only fastback limousine.  Although not entirely accurate, there are reasons the 1970s came to be called “the decade style forgot”.
