Start with what the Triumph TR8 is: a 2-door Roadster (automobile) / roadster / 2-door coupé with 3528 cc Rover V8, built from 1978 to 1981, as the oil crises and the first emissions rules rewired the industry. What it meant takes a little longer. The shape is credited to Harris Mann.
Where it came from
The Triumph TR8 is a sports car built by the British Triumph Motor Company from 1978 until 1981. It is an eight-cylinder version of the "wedge-shaped" Triumph TR7 which was designed by Harris Mann and manufactured by British Leyland (BL), through its Jaguar/Rover/Triumph (JRT) division. The majority of TR8s were sold in the United States and Canada.
Under the skin
The engine is 3528 cc Rover V8. On the scales it comes to 1203.9 kg. Drive goes through a 5-speed manual. The layout matters: a front engine drives the rear wheels, the classic proportion — long bonnet, cabin set back — that most people picture when they picture a sports saloon or a grand tourer. The wheelbase is 2160 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
In context
In the Triumph line-up the Triumph TR8 has a clear place: it replaced the Triumph TR7; the factory was Speke, Liverpool. The cars a buyer would have weighed it against include the Toyota Supra, the GM (General Motors) Saab 900, the Mazda RX-7. Nearby in the Triumph catalogue sit the Triumph SD2 and the Triumph Renown.
Owning one today
MotorJury scores cars on the United States complaint and recall record, and the Triumph TR8 has none: too old, too rare, or never sold there. Its value today is a collector's question, decided by provenance and condition rather than by a class average.
