The Triumph TR range of cars was built between 1953 and 1981 by the Triumph Motor Company in the United Kingdom. Changes from the TR2 to the TR6 were mostly evolutionary, with a change from a live axle to independent rear suspension in 1965 and a change from a four-cylinder engine to a six-cylinder engine in 1967. An all-new TR7, with a unit body, an overhead camshaft four-cylinder engine, and a live rear axle, was introduced in late 1974. The TR8, a development of the TR7 with a Rover V8 engine, was introduced in 1979 and was sold alongside the TR7 until TR production ended.
The Triumph TR-X, also known as the "Bullet", was the first Triumph car to use the TR designation. It was first shown to the public at the Paris Auto Show in late 1950. Envisioned as a personal luxury car, it had envelope styling with aluminium body panels, spats over the rear wheels, electro-hydraulically operated seats, windows, and top, onboard hydraulic jacks, electrically-operated hidden headlights, and a power radio aerial. The TR-X used the Standard Vanguard's frame and engine, the Triumph Renown's suspension, Laycock de Normanville electrically operated overdrive, and a 94 inch wheelbase. The top speed was estimated as 90 mph (140 km/h)
The TR-X was discontinued after three prototypes had been built. Some of the electro-hydraulic systems broke down during a demonstration of a TR-X to Princess Margaret, Countess of Snowdon. Standard could not develop and manufacture a car that complicated and still sell it at a profit. The car would also not have been competitive against the Jaguar XK120.Fisher and Ludlow and Mulliners both refused to build bodies for the TR-X, and negotiations with Italian firms Carrozzeria Touring and Pininfarina also failed. Material shortages caused by the Korean War ended attempts to manufacture the TR-X. Two of the prototypes were sold; it was reported in 2011 that these still existed.
