BMW E9 - 2.5CS

2.5CS

The last version of the E9 to be introduced was the 2.5CS in 1974. This was a response to the 1973 oil crisis, such that the buyer could choose the smaller, more economical engine. The engine, from the 2500 sedan, displaced 2,494 cc (152.2 cu in) and produced 150 horsepower (110 kW) at 6000 revolutions per minute. Only 874 were made until the end of E9 production in 1975, and none were exported to the United States.'
