The BMW E24 was the first generation of BMW 6 Series grand tourer coupes BMW produced, production of the E24 lasted from 1976 to 1988. It replaced the E9 coupes and was replaced, after a 16-year hiatus, in 2004 by the E63 6 Series. Aside from the M635 CSi, the E24 was powered by a range of M30 straight-6 engines.

The E24 M635 CSi (called the M6 in the United States and Japan) is considered the start of the M6 model line. In most markets, the M635 CSi was powered by the M88 straight-6. In the United States and Japan, the M6 was powered by the less powerful S38 straight-6 engine.

The initial proposal for the E24 was a based on a BMW E9 3.0 CS with an increased height, in order to make it easier for customers to get into the car. However, Bob Lutz rejected the proposal, eventually leading to the shape of the E24 in its production form. Unlike its E9 predecessor, the body of the E24 had a B pillar.

Production started in March of 1976 with two models: the 630 CS and 633 CSi. Originally the bodies were manufactured by Karmann, but production was later taken in-house to BMW. Initially, the E24 was based on the E12 5 Series platform.

The M version of the E24, the M635 CSi, was first introduced at the Frankfurt Motor Show in 1983. In 1987 it was also introduced in the United States and Japan, as the M6.

The M635 CSi is powered by a 282 hp version of the M88 engine. United States and Japan models were powered by a 252 hp version of the S38 engine, which has a lower compression ratio and uses a catalytic converter. Over its production life of 1983-1988, 4,088 M635 CSi’s were built.
