The M635CSi was launched in 1985 as the M version of the E24 6 Series, produced from 1976 to 1989. The M635CSi is impressive given that the E24 had only minor changes throughout its long production run. The M635CSi’s narrow and sharp styling led to it being nicknamed the “sharknose”. It is also one of the most significant BMW M cars, as the Paul Baroq styling was combined with the M1’s motorsport-derived engine. This is a car that can be comfortably daily-driven, while driving as fast as the Ferraris of its time. For the Japanese and US markets, the M635CSi was sold as the “M6” with a setup different to its European counterpart.
The M1, BMW’s only supercar, is known for its unfortunate fate as a racing car, as it was powered by the legendary dry sump “M88/1” DOHC engine. The M635CSi is powered by the third iteration of the original engine, the “M88 /3”. This engine was modified to a wet sump and SOHC, with an additional injection to 6 throttle valves fitted at a 30 degree angle and a second generation Bosch Motronic ECU.
However, the Japanese-spec M6 was powered by a detuned version of the M88/3, the S38B35 (simply called the S38) engine. The main difference is that the S38’s exhaust manifold and muffler were iron-casted and equipped with a catalyst, which was designed to comply with the stringent regulations of North America and Japan. The S38’s output reaches 260 ps and accelerates from 0-100 km/h in 6.1 seconds, at a maximum top speed of 255 km/h.
This example is from 1986. It was parallel imported to Japan as a brand-new car, and was first registered for road use in July, 1986.
Showing 58,460km on the odometer, this M635CSi is still in great condition. What stands out is the solid black (086) exterior, which is a very rare color for an E24. This is a fantastic chance to get your hands on an E24 in superb condition.
