|When the Specialist Division 1, or Rover 3500, was first designed by British Leyland as a successor to the P6, the key was simplicity. That meant a live rear axle instead of De Dion-type rear suspension and a redesigned Rover V8 which emphasized torque over horsepower, rather than the newer 2.2L four cylinder. It’s been called the best-designed British car ever, taking cues from the likes of Ferrari and Maserati, but was often plagued with production issues early in its run. As a result, by 1984, the SD1 had seen some cosmetic and mechanical changes, as well as an expansion to a four cylinder model.|

The SD1 (Specialist Division 1) was manufactured by British-Leyland division Rover from 1976 to 1986 to replace both the Rover P6 and Triumph 2000 for the executive car segment. Its name is a reference to Specialist Division, which encompassed British Leyland's upmarket car brands Jaguar, Rover and Triumph.
Styled similarly to contemporary European exotics such as the Ferrari 365 GTB/4, the SD1 brought supercar-inspired design to executive cars, although it had to make with a small development budget from loss-ridden British-Leyland.
The SD1 was based on a modest front-engine, rear-wheel drive platform using a live rear axle and rear drum brakes.
The Vitesse trim came with the Rover V8, a 3.5 liter engine with all-aluminum construction and pushrod valvetrain.
