The Rover P6 series (named 2000, 2200, and 3500 for their engine displacement) was a group of saloon automobiles produced from 1963 through 1976. It was replaced by the Rover SD1.
2000
The first P6 used a 2.0 L (1978 cc/120 in³) engine. Power was somewhat lacking compared to the Triumph 2000, but the 1966 2000TC made the two competative. Later 2000SC models featured a single carburettor.
3500
Rover saw Buick's compact 3.5 L (3528 cc/215 in³) V8 from the Buick Special as a way to differentiate the P6 from its chief rival, the Triumph 2000. They purchased the rights to the innovative aluminum engine, and it became an instant hit. The Rover V8 engine, as it became known, outlived its original host by more than three decades.
The 3500 was produced from 1968 (one year after the Rover company was purchased by Triumph's owner, Leyland) through 1976. A automatic transmission was the only option until the 1971 addition of the manual 3500S.
2200
The 2200SC and 2200TC were the final P6 cars. Produced from 1973 through 1976, they used a 2.2 L (2205 cc/134 in³) version of the 2000s engine.
