Background
Like most things associated with the newly formed British Leyland the development of the TR7 was akin to the Twelve Trials of Hercules for all those involved. From the conglomerate’s inception in 1968, perennial sports car rivals, MG and Triumph, were now on the same team….supposedly. What’s more this now meant that these recently combined entities needed to replace five cars – Midget, MGB, Spitfire, GT6, TR6 – with just one. Funds, inevitably, were just too tight for a sophisticated, differentiated and multi-marque offering. Any new sports car didn’t just have big boots to fill, it now had five pairs!
Of course, both MG and Triumph teams had their own potential successors on the drawing boards. MG’s hopeful was the ADO21, a tapered nosed mid-engined offering with very few carry overs from other group offerings. Triumph, meanwhile, were touting a prototype named “Bullet.” The Bullet was a much more conventional front-engined car, using existing saloon car running gear. Can you see where this is going?
Ultimately, the creaking conglomerate’s decisions were made much easier by its equally creaking finances. Bespoke and innovative MG versus conventional Triumph that uses existing group componentry? There was only ever going to be one winner. And so, the Bullet was green-lit and despite it having been in the Triumph works since 1969, all the Group’s resources fell behind the car in 1971. There were changes to come, however. The Bullet concept had been a targa topped car in the mould of the Fiat X1/9 or the Porsche 914. With the ever-tightening regulations in the USA threatening to sound the death knell for all convertibles, British Leyland dropped the targa roof. Also, with the Bullet lacking some theatre and character that the name might suggest, Harris Mann was enlisted to spruce up the design concepts somewhat.
The new TR7 was launched in January 1975 in the USA but not until May 1976 on its home market. The car was relatively well received initially but with many finding the car’s “turret top” roof its most divisive feature. Luckily then, in 1979 the TR7 drophead coupe was launched with long-time Triumph collaborator Michelotti making the tweaks to the Harris Mann original coupe. With the arrival of the convertible many pundits felt that the TR7 had finally become the car it had always promised to be.
