Triumph TR7 Drophead
The Triumph TR7, launched in 1975, was one of the most controversial British sports cars ever produced. Harris Mann's dramatic wedge-shaped design divided opinion sharply, and the decision to launch it as a fixed-head coupe rather than a convertible bewildered TR traditionalists. However, when the Drophead convertible version finally appeared in 1979, many of the car's critics were won over.
The TR7 Drophead transformed the car's character. The wedge design, which could look heavy and closed as a coupe, gained a new lightness and elegance with the roof removed. The proportions worked better, and the car finally looked like the sports car it was intended to be. The convertible top was simple but effective, folding neatly behind the seats.
The 2.0-litre overhead-cam four-cylinder engine produced 92 horsepower in European specification, adequate if not exciting performance for a car of this weight. The five-speed gearbox, available on later cars, improved the driving experience significantly over the four-speed unit. The engine was smooth and willing, if not particularly powerful.
Handling was actually one of the TR7's strengths. The MacPherson strut front suspension and live rear axle on coil springs provided predictable, safe handling with decent grip. The car was well-balanced and stable at speed, if not as involving as the earlier TR6. The rack-and-pinion steering was precise and well-weighted.
The TR7's troubled production history saw it built at three different factories — Speke in Liverpool, Canley in Coventry, and finally Solihull. Industrial relations problems, quality control issues, and British Leyland's general malaise all contributed to a reputation for unreliability that was not entirely deserved, particularly on later Solihull-built cars.
Total TR7 production reached 112,368 units, with the Drophead convertible accounting for approximately 28,000. Despite its controversial reputation, the TR7 was actually a commercial success relative to its predecessors. Today, the Drophead version has become the preferred choice among enthusiasts, and well-maintained examples are increasingly appreciated for their distinctive styling and straightforward mechanical simplicity.
Rust is the major concern, particularly in inner sills, outer sills, A-posts, rear arches, and the convertible-specific rear floor area. Solihull-built cars (1980-1981 model years) are generally better built. The 2.0 engine is reliable but check for head gasket issues. Five-speed gearbox is more desirable than four-speed. Convertibles are significantly more valuable than coupes. Check hood mechanism condition and weather sealing. Many parts are shared with other BL vehicles, ensuring reasonable availability.
Produced at three different factories: Speke (1975-1978), Canley (1978-1980), and Solihull (1980-1981). The Drophead convertible was introduced in 1979 and is generally considered more desirable. Solihull-built cars are typically of higher quality. Total production was 112,368 units across all variants.
