Triumph Spitfire Mk1
The first Spitfire, sold as the Triumph Spitfire 4 and built from 1962 to 1964: a Herald underneath, a body by Michelotti, and wind-up windows that the Sprite and Midget lacked. It is now known as the Mk I, also written Mk1 or Mark 1, though it was never badged so.

In October 1962 Standard-Triumph showed a small new sports car at the London Motor Show at Earls Court, and its Canley works began building it that month. It was the Triumph Spitfire 4, and the 4 counted its cylinders.
Although never badged or promoted as a Mk1 this name stuck as the later models arrived.
Canley built it until December 1964, when the Spitfire 4 Mk II replaced it. It is not the Mk IV, a different car of 1970; the versions page sorts out the names.source 1source 2source 3
What it was

Harry Webster, Standard-Triumph's technical chief, wanted a sports car made from the Herald to take on the Austin-Healey Sprite. The Spitfire 4 was that car: mostly Herald underneath, so that little new tooling was needed, under a body by Giovanni Michelotti. Graham Robson points out why a separate chassis made sense: a body on a frame was much cheaper than a monocoque, and a restyle, or a shorter frame, would not take years or cost millions.
The frame was the Herald's backbone, shortened, with its outer rails and rear outriggers cut away, and the sills (rocker panels) were made structural in their place. The front suspension, with double wishbones and coil springs, came from the Herald, and so did the swing axles on a transverse leaf spring at the back. Discs braked the front wheels and a rack and pinion steered them, and to reach the engine the bonnet (hood) and both front wings (fenders) swung forward as one.
Its doors had exterior handles and wind-up glass windows, which neither the Sprite nor the MG Midget then offered, and the doors and boot (trunk) locked. The windscreen (windshield) had washers, the steering column could be set for reach with a spanner, and the instruments sat together in the middle of the dashboard, so that the car could be built with its steering wheel on either side. A heater was an extra. In its launch advertisement Standard-Triumph made a selling point of the turning circle:
TIGHTER TURNING Whip the Spitfire round in one go (24 ft is all you need) while other cars are making the 3-point turns!
The same car was the starting point for the works team's Le Mans and rally Spitfires of 1964 and 1965, whose story is on the racing page. How the Spitfire came to be built, and the rivals it was sold against, are on the history page.source 4source 1source 5source 6source 3source 7source 8source 9source 10
How to spot a Spitfire 4
The Spitfire 4 and the Mk II share a body, so telling them apart comes down to a few details, and the commission number settles it.
The grille
Two halves of fine mesh, as German Wikipedia describes them. The Mk II has horizontal bars.
The bumpers
Low at both ends, with overriders (bumper guards) front and rear. The Mk III raised the front bumper to cross the grille.
The boot lid
No Mark on it. The Mk II's lid carries its Mark.
The floor
Rubber mats. Moulded carpets came with the Mk II.
The hood
A hood (soft top) on separate sticks, stowed in the boot when down. The folding hood came with the Mk III.
The number
A commission number between FC1 and FC44656, by the Vintage Triumph Register's list. The Mk II's begin at FC50001.
Within the run, triumphspitfire.com's change log, which cites no sources, records smaller changes by commission number, among them a larger clutch from about FC17136 and the end of the separate header tank at about FC39925. How to read the plate, and what a British Motor Museum Heritage Certificate adds, are explained on Identification.source 11source 3source 12source 13source 9source 14source 15source 16


How many were built
Two production figures for the Spitfire 4 are in print, made of the same digits in a different order. The Triumph Sports Six Club and Classic & Sports Car print the one the production figures below lead with, and Wikipedia cites Graham Robson's book of 1982 for it; Canley Classics prints the other, and the Dutch Triumph Spitfire Club copies Canley's table. None of them says what it counts. The commission numbers do not settle it either: the Spitfire 4's range holds fewer numbers than either figure, no source read explains why, and the identification page sets them side by side.
Some Spitfire 4s were put together abroad from kits. In South Africa, Motor Assemblies of Durban began building them in July 1963, and Classic Car Africa, using NAAMSA sales figures, counts those sold there; that count is among the production figures below. In Australia, Australian Motor Industries assembled them and painted them in its own Dulux colours.source 12source 14source 17source 2source 18source 13source 3source 19

Price and options
The price came down within six months of the launch. Standard-Triumph's advertisement of November 1962 gave one price and Motor Sport a lower one in April 1963, both including purchase tax, the second after a cut in the tax. The specification below gives both, with their sources.
Overdrive followed: a Laycock unit working on third and top gears, offered from October 1963 for the 1964 model year. Wire wheels and a steel factory hardtop were added for the same model year, and from 1964 the factory sold tuning kits, usually through SAH, mainly to satisfy the homologation rules for its racing.source 8source 9source 12source 14source 7source 20

On the road
Bill Boddy drove two Spitfires for Motor Sport's April 1963 issue and took his performance figures with two people aboard; they are in the specification below.
The little 1,147-c.c. Triumph is purely a sports car, lively, fun to drive, making appropriate noises—a travelling motor-race—and sticking well to the road.
He liked the gearchange, with synchromesh on the top three gears, the light and accurate steering and a turning circle he called astonishing. The lower gears he thought too low: first and second ran out at 40 and 71 km/h (25 and 44 mph). In corners the swing axles turned mild understeer into oversteer once the rear wheels reached positive camber, and he found the suspension fairly hard, enough for bad roads to set the car rattling. He missed an oil-pressure gauge, and the brakes wanted a firm push.
Road & Track tested the Spitfire 4 in April 1963, and Autocar tested it too, but no source read reprints either test: triumphspitfire.com's uncited table gives their figures, and Practical Classics printed the same figures in 2000 without naming a source. The road tests page sets the period tests side by side.
The Mk II of December 1964 kept the gearbox (transmission) and the swing axles, and gave the car more power and thicker-padded seats.source 9source 21source 3source 14
