The Rover SD1 is both the code name and eventual production name given to a series of executive cars built by the Specialist Division (later the Jaguar-Rover-Triumph division) , and finally the Austin Rover division of British Leyland from 1976 until 1986, when it was replaced by the Rover 800. The SD1 was marketed under various names. In 1977 it won the European Car of the Year title. In "SD1", the "SD" refers to "Specialist Division" and "1" is the first car to come from the in-house design team. The SD1 was the final Rover-badged vehicle to be produced at Solihull. Future Rover models would be built at the former British Motor Corporation factories at Longbridge and Cowley. History Background In 1971, Rover, at that time a part of the British Leyland (BL) group, began developing a new car to replace both the Rover P6 and the Triumph 2000/2500. The designers of both Triumph and Rover submitted proposals for the new car known as the Triumph Puma and Rover P10 respectively, of which the latter was chosen. David Bache was to head the design team, inspired by exotic machinery such as the Ferrari Daytona and 365 GTC/4, and the late 1960s design study by Pininfarina for the BMC 1800, which also guided the design of the Citroën CX. Spen King was responsible for the engineering. The two had previously collaborated on the Range Rover. The project was first code-named RT1 (for Rover Triumph Number 1) but then soon changed to SD1 (for Specialist Division Number 1) as Rover and Triumph were put in the new "Specialist Division" of British Leyland. Design The new car was designed with simplicity of manufacture in mind in contrast to the P6, the design of which was rather complicated in areas such as the De Dion-type rear suspension. The SD1 used a well-known live rear axle instead. This different approach was chosen because surveys showed that although the automotive press was impressed by sophisticated and revolutionary designs the general buying public was not unless the results were good. However, with the live rear axle came another retrograde step – the car was fitted with drum brakes at the rear. Rover's plans to use a new 2.2-litre DOHC 16-valve Slant-Four engine with Bosch L-Jetronic fuel injection were soon abandoned as BL management ruled that substantially redesigned versions of Triumph's six-cylinder engine were to power the car
