BMW M635 CSI

About the BMW M635 CSI

BMW Motorsport introduced M 635 CSi in Europe at the Frankfurt Motor Show in 1983. It is essentially an E24 powered by the powerplant of the BMW M1 - the M88 (286 PS (210 kW; 282 hp)). Most of the cars were equipped with special metric 415 mm diameter wheels requiring Michelin TRX tires. A catalyzed, lower compression ratio version of the car with the S38 engine (260 PS (190 kW; 260 hp)) was introduced in the U.S. in 1987. All M6 cars came standard with a 25% rear limited slip differential. U.S. models included additional comforts that were usually optional on models sold in Europe such as Nappa leather power seats and a dedicated rear A/C unit with a center beverage chiller. Car and Driver tested a U.S. M6 in July 1987 and achieved a 0-60 time of 6.1 seconds, better than the BMW published 6.4 and 6.8 second times for the European and U.S. versions respectively. 4,088 M 635CSi cars were built between 1983 and 1988 with 1,767 U.S. M6 built.
