The Triumph Spitfire was a small British two-seat sports car, introduced in 1962. The vehicle was based on a design produced for Standard-Triumph in 1957 by Italian designer Giovanni Michelotti. The codename for the vehicle was the "Bomb". The car was largely based on the Triumph Herald small saloon, and throughout its life was built at the Standard-Triumph works at Canley, Coventry.

The Triumph Spitfire was originally devised by Standard-Triumph t- compete in the small sports car market which had opened up with the introduction of the Austin-Healey Sprite. The Sprite had used the basic drive train of the Austin A30/35 in a light body t- make up a budget sports car; Triumph's idea was t- use the mechanics from their small saloon, the Triumph Herald, t- underpin the new project. Triumph had one advantage, however; where the Austin A30 range was of unitary construction, the Herald featured a separate chassis; it was Triumph's intention therefore t- cut that chassis down and clothe it in a sports body, saving the costs of developing a completely new chassis/body unit.

The Italian designer Michelotti?wh- had already penned the Herald?was commissioned for the new project, and came up with a traditional, swooping body. Wind-up windows were provided (in contrast t- the Sprite/Midget, which still featured sidescreens at that time), as well as a single-piece front end which tilted forwards t- offer unrivalled access t- the mechanics. At the dawn of the 1960s, however, Standard-Triumph was in deep financial trouble, and unable t- put the new car int- production; it was not until the company was taken over by the Leyland organization that funds became available and the car was launched. Leyland officials, taking stock of their new acquisition, found Michelotti's prototype hiding under a dustsheet in a corner of the factory and rapidly approved it for production.

The production car changed little from the prototype, although the full-width rear bumper was dropped in favour of tw- part-bumpers curving round each corner, with overriders. Mechanics were basically stock Herald components: The engine was a 4-cylinder of 1147 cc, mildly tuned for the Spitfire with twin SU carburettors. Als- from the Herald came the rack and pinion steering and coil-and-wishbone front suspension up front, and at the rear a single transverse-leaf swing axle arrangement. This ended up being the most controversial part of the car: it was known t- "tuck in" and cause violent over steer if pushed to- hard, even in the staid Herald. In the sportier Spitfire (and later the 6-cylinder Triumph GT6 and Triumph Vitesse) it led t- severe criticism. The body was bolted t- a much-modified Herald chassis, the outer rails and the rear outriggers having been removed; little of the original Herald chassis design was left, and the Spitfire used structural outer sills t- stiffen its body tub.

The Spitfire was an inexpensive small sports car and as such had very basic trim, including rubber mats and a large plastic steering wheel. These early cars were referred t- both as "Triumph Spitfire Mk I" and "Spitfire 4", not t- be confused with the later Spitfire Mark IV.

From 1964 an overdrive option was added t- the four speed gearbox t- give more relaxed cruising. Wire wheels and a hard top were als- made available.

Spitfire MkII Triumph Spitfire Mark 2 Production 1965-1967 37,409 made Engine(s) 1147 cc Straight-4

In March 1965 the Spitfire Mk II was released and was very similar t- the Mk I but featured a more highly tuned engine, through a revised camshaft design, a water cooled intake manifold and tubular exhaust manifold, increasing the power t- 67 bhp (50 kW) at 6000 rpm. This improved the top speed t- 92 mph (148 km/h). The coil-spring design clutch of the Mk I was replaced with a Borg and Beck diaphragm spring clutch. The exterior trim was modified with a new grille and badges. The interior trim was improved with redesigned seats and by covering most of the exposed surfaces with rubber cloth. The original moulded rubber floor coverings were replaced with moulded carpets.

It was introduced at a base price of 550 while the Sprite was priced at 505 and the Midget at 515. Top speed was claimed t- be 96 mph (154 km/h) and its 0-60 mph time of 15.5 seconds was considered "lively." The factory claimed that at highway speeds (70 mph (110 km/h)) this lively car achieved 38.1 mpg?imp (7.41 L/100 km / 31.7 mpg?U.S.).

Spitfire Mk 3 Triumph Spitfire Mark 3 1969 Triumph Spitfire MK3 Production 1967-1970 65,320 made Engine(s) 1296 cc Straight-4

The Mk 3, introduced in March 1967, was the first major facelift t- the Spitfire. The front bumper was raised in response t- new crash regulations, and although much of the bonnet pressing was carried over, the front end looked quite different. The rear lost the overriders from the bumper but gained reversing lights as standard (initially as tw- separate lights on either side of the number plate, latterly as a single light in a new unit above the number plate); the interior was improved again with a wood-veneer instrument surround. A folding hood replaced the earlier "build it yourself" arrangement. For most of the Mk 3 range, the instrument cluster was still centre-mounted (as in the Mk 1 and Mk 2) s- as t- reduce parts bin counts (and thereby production costs) for RH- and LH-drive versions. Starting in 1969, however, US-bound models were produced with a "federal" dashboard design which moved the gauges in front of the driver, a layout that would be adopted for all markets with the Mk IV. The 1147 cc engine was replaced with a bored-out 1296 cc unit, as fitted on the new Triumph Herald 13/60 and Triumph 1300 saloons. In twin-carburettor form, the engine put out a claimed 75 bhp (56 kW) and made the MK 3 a comparatively quick car by the standards of the day.[citation needed] Popular options continued t- include wire wheels, a hard top and a Laycock de Normanville overdrive, and far more relaxed and economical cruising at high speeds. The Mk 3 was the fastest Spitfire yet, achieving 60 mph (97 km/h) in 12.5 seconds.[citation needed] The Mk 3 actually continued production int- 1971, well after the Mk IV was introduced.

The MK IV brought the most comprehensive changes t- the Spitfire. It featured a completely re-designed cut-off rear end, giving a strong family resemblance t- the Triumph Stag and Triumph 2000 models, both of which were als- Michelotti-designed. The front end was als- cleaned up, with a new bonnet pressing losing the weld lines on top of the wings from the older models, and the doors were given recessed handles. The interior was much improved: a proper full-width dashboard was provided, putting the instruments ahead of the driver rather than over the centre console. The engine continued at 1296 cc, but was modified with larger big-end bearings t- rationalize production with the TR6 2.5 litre engines, which somewhat decreased its "revvy" nature; there was some detuning, t- meet new emissions laws, which resulted in the new car being a little tamer than the MK 3. The gearbox gained synchromesh on its bottom gear.

By far the most significant change, however, was t- the rear suspension, which was de-cambered and redesigned t- eliminate the unfortunate tendencies of the original swing-axle design. The Triumph GT6 and Triumph Vitesse had already been modified, and the result on all these cars was safe and progressive handling even at the limit.

The Mk IV went on sale in the UK at the end of 1970 with a base price of 735.

In 1973 in the US and 1975 for the rest of the world, the 1500 engine was used t- make the Spitfire 1500; though in this final incarnation the engine was rather rougher and more prone t- failure than the earlier units, torque was greatly increased which made it much more drivable in traffic. The reason for the engine problems was due t- continued use of three main bearings for the crank shaft.

The US market models were considerably less powerful than the British market cars because they had t- meet more stringent US emissions requirements. While the rest of the world saw 1500s with the compression rati- reduced t- 8.0:1, the American market model was fitted with a single Zenith-Stromberg carburettor and a compression rati- reduced t- 7.5:1 t- allow it t- run on lower octane unleaded fuel and after adding a catalytic converter and exhaust gas recirculating system, the engine only delivered 53 bhp (40 kW) with a 0-60 time of 14.3 seconds.

The notable exception t- this was the 1976 model year, where the compression was raised t- 9:1.

American market cars als- suffered from poorer handling due t- the longer front springs that Triumph fitted t- bring the headlights up t- the height required by US law. American market Spitfire 1500s are easily identified by their big plastic overiders, and wing mounted reflectors on the front and back wings. The US specification model years of 1978 and previous still have chrome bumpers, however the 1979 and 1980 models were fitted with black rubber bumpers with built-in overriders, and chassis extensions were fitted under the boot t- support the bumpers. Detail improvements continued t- be made throughout the life of the MK IV, and included reclining seats with head restraints, wood-veneer dash, hazard flashers and electric washers (previously these had been operated by a manual pump on the dashboard). Options such as the hard top, tonneau cover, map light and overdrive continued t- be popular, though wire wheels ceased t- be available.

The 1980 model was the last and the heaviest of the entire run weighing in at 1875 lb (850.5 kg). Base prices for the 1980 model year were $5,995 in the US and 3631 in the UK. The last Spitfire, an Inca Yellow UK-market model with hardtop and overdrive, rolled off the assembly line at Canley in August 1980, shortly before the factory closed.
