A brief history of the Triumph TR
Triumph TR2 and TR3
The Triumph TR2, first shown in March 1953 at the Geneva Motor Show, was an evolution of the Triumph 20TS with a larger boot, built on an all-new frame with revised suspension and brakes and an uprated engine.. The TR2 formed the basis of the evolution of the TR line up to the TR6
The TR3, introduced in 1955, had a front grille, a more powerful engine and in October 1956, the front brakes were changed from 10 in drums to 11 in discs. After a restyle in 1957, the TR3 was available with a larger 2.2 litre and the car was unofficially known as the TR3A. A further development, with the larger engine as standard and with a fully synchromesh gearbox, was made available in 1962, the final year of TR3 production. This last version of the TR3 was unofficially known as the TR3B.
Triumph TR4
Introduced in 1961, the TR4 had a completely new body designed by Giovanni Michelotti. The TR4 was upgraded to the TR4A in 1965 with the addition of independent rear suspension
In 1967, the TR line was updated with servo-assisted brakes and a 2.5 L version of the straight-six engine that had been used in the Triumph 2000. and the TR5 with Lucas fuel injection for the rest of the world.
The TR5 was replaced by the TR6 in 1968. The main difference between the TR6 and the TRs it replaced was its styling. The front and rear ends of the car had been restyled by German coachbuilder Karmann, giving the car a more contemporary appearance.
Trumph TR7 and TR8
The Triumph TR7 was introduced in 1974. While all previous TRs were evolutionary designs developed from the TR2, the TR7 was an all new design owing nothing but its model designation to the earlier TRs. While the TR7's unit body and wedge shape were advertised by Leyland as major improvements, these were offset by the TR7's return to a four-cylinder engine and a live rear axle.
The TR7 was initially available as a coupé, with a convertible version being developed after the launch of the coupé. A premium-grade version using the Rover V8 engine was developed as part of the same project. Both the TR7 convertible and the premium V8 version, renamed the Triumph TR8, were introduced in 1979.
The TR7 and TR8 were discontinued in 1981.
