Triumph Spitfire Mk3

Triumph Spitfire Mk3
 The Mark III, introduced in March 1967, was the first major facelift to the Spitfire. The front bumper was raised in response to 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 two 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 Mark III range, the instrument cluster was still centre-mounted (as in the Mark I and Mark II) so as to reduce parts bin counts (and thereby production costs) for right-hand and left-hand drive versions.

The 1147 cc engine was replaced with a bored-out 1296 cc unit (the bore increasing from 69.3 mm (2.73 in) to 73.7 mm (2.90 in), stroke retained at 76 mm (3.0 in)), as fitted on the new Triumph Herald 13/60 and Triumph 1300 saloons. In SU twin-carburettor form, the engine put out a claimed 75 bhp (56 kW), and 75 lb·ft (102 N·m) of torque at 4000 rpm, and made the Mark III a comparatively quick car by the standards of the day.[citation needed] Popular options continued to include wire wheels, a hard top and a Laycock de Normanville overdrive, and far more relaxed and economical cruising at high speeds. The Mark III was the fastest Spitfire yet, achieving 60 mph (97 km/h) in 14.5 seconds, and reaching a top speed of 95 mph (153 km/h). Average fuel consumption was improved slightly at 33mpg. The Mark III actually continued production into 1971, well after the Mark IV was introduced.

On 8 February 1968, Standard-Triumph General Manager George Turnbull personally drove the 100,000th| Triumph Spitfire off the end of the Canley production line. More than 75% of the total production had been exported outside the UK, including 45% to the USA and 25% to mainland European markets.

Starting in 1969, however, US-bound models had to be changed to comply with new safety/emission regulations; models produced after 1969 are sometimes referred to as "federal" Spitfires. The changes included a slight decrease in power (68 bhp) due to emissions control, the instrument panel was moved in front of the driver, and new seats were introduced with integrated headrests to help against whiplash. Also the wood dash was replaced with a matte black finish.
