The BMW E24 is the first generation of BMW 6 Series range of grand tourer cars, which was produced from January 1976 to 1989 and replaced the BMW E9 coupé.

The E24 was produced solely in a 2-door coupé body style. All models used petrol straight-six engines, with the majority (aside from the M635CSi/M6 model) using a version of the BMW M30 engine family. The E24 was initially based on the E12 5 Series platform, until it switched to the newly-released E28 5 Series platform in 1982. Considered the finest example of contemporary BMW styling, good original E24s, particularly early Karmann built examples are now quite rare and have become highly collectable, along with the later M6 and Alpina variations.

The M635CSi is the first of the BMW M6 model line and is powered by the M88/3 straight-six engine. In North America, the vehicle is badged as "M6" and uses the less powerful BMW S38 engine.

In 1985, the 633CSi was replaced by the 635CSi for the North American Market. This model uses the M30B34 engine, which produces 136 kW (182 hp) and 290 N⋅m (214 lbf⋅ft) at 4,000 rpm. An L6 "luxury edition" version of the 635CSi was available in North America for the 1987 model year. The L6 featured leather headliner and trim and an automatic gearbox.

In 1988, the engine was upgraded to the M30B35. This engine has a capacity of 3.4 Litres (despite the model code and the "3.5" inscribed on the intake manifold) and produces 155 kW (208 hp) and 305 N⋅m (225 lbf⋅ft) torque. This upgraded engine resulted in catalytic converter equipped United States models offering similar performance to European models. Self-leveling rear suspension was added to the 635CSi and M6 features list.
