A Brief History of the TR8
The design concept of the car by Harris Mann initially configured it as a Fixed Head Coupe to meet USA safety requirements. The "wedge", as we know it, was first envisaged in 1969
at Canley and codenamed “Bullet”. Two engine options were envisaged, the two litre slant four and the Rover V8. Of the latter, the experimental cars were designated X840 (TLB 254M),
X843(UXC 582M), X858(V8 engined car for pave testing) and X859(a further V8 engined car). At the same time the Lynx project began to take shape, this being a long wheelbase 2+2
derivative of the “Bullet”. Again experimental cars were built and designated X882(MYX 411P Red), X884, X891(WUY 952R White), and X905(BHP 2T Green). Of these only X905
survives and can still be seen at B.M.I.H.T. Gaydon.
Thus in 1974 a pre-production batch of TR7 coupes was hand built and sent to the USA for evaluation. Although the car was designed to accept the Rover V8 engine, costing
constraints dictated that initially the four cylinder would be fitted. 1975 saw the first production TR7's and by 1976 the US dealers were clamouring for the V8 engined version. In 1977 some
150 TR7V8 Fixed Head Coupes were built on the production line and 95% shipped to the US for evaluation. The remaining few were retained for test purposes in the UK.
Whilst this was happening the US reviewed its policies and reversed the decision to make open topped cars illegal. Immediately the Rover Triumph engineers set about redesigning the
coupe into Drop Head or convertible form. With the design work already completed for the V8 drivetrain, it was not long before the first TR7V8 convertibles, or TR8s as they were later known,
were being built. A number of prototypes with the prefix ACT were built - of these two are known to exist in England with possibly two more in Scotland.
Production began at the Speke, factory in 1977 but, with all the labour problems, it was switched to the Canley factory in 1978. The building of TR7's & TR8's continued there until
1980 when production was transferred to Solihull. The last car was built on 5th October 1981. A combined total of 114,463 cars were built. Of these approximately 2,800 were TR8's.
A breakdown of the production history relating to the TR8 is as follows:
