The TR7 was introduced in 1975 as a replacement for the TR6, with a design that departed from the classic roadster look. It featured a wedge-shaped design, influenced by the trends of the time. The design was more angular and modern, reflecting the styling preferences of the 1970s. The TR7 was available in both coupe and convertible versions. Initially, the TR7 was powered by a 2.0-liter four-cylinder engine, and later models included a 2.0-liter eight-valve four-cylinder engine.The TR8 was essentially a more performance-oriented version of the TR7, featuring a V8 engine. The TR8 was introduced in 1978 and was powered by a 3.5-liter Rover V8 engine, providing improved performance compared to the four-cylinder engine in the TR7. The V8 engine was mated to either a manual or automatic transmission, and the TR8 featured wider wheels and tires for better handling. The TR8 was available only as a convertible. Despite the improvements in performance, the TR8 faced challenges, including the overall economic climate, and production was limited.
