The BMW 6-Series is an automobile launched in August, 1976 to replace the 3.0CS and 3.0CSi with the 630 CS and the 633 CSi. The 6 was dropped in 1989 and later replaced by the 8-Series, although the line was relaunched in 2003 as an entirely new vehicle.

E24 6-Series (1976–1989)

The original 6-Series replaced older BMW models (specifically, the 3.0CS and 3.0CSi). The new E24 chassis was safer than that of the E9 and met new United States federal crash and rollover standards.

The 630 CS used a 2986 cc Straight-6 M30 motor with a Solex 4A1 carburetor, making 184 hp (137 kW) at 5800 rpm. The 633 CSi used the same engine, but with a Bosch Motronic fuel injection system, which increased output to 200 hp (150 kW).

In 1987 BMW took the M88/3, a modified version of the M88/1 from the BMW M1 and put it in the E24 chassis, creating the M635CSi, the US variant of which was called the M6. The M6 also had improved suspension, brakes, and a close ratio manual gearbox.

All were built in Dingolfing, Germany.

E63/E64 6-Series (2003–present)

In 1989 the 6-Series was supplanted by the 8-Series, but in late 2003 the 6-Series was reintroduced (as a 2004 model), with Coupe and Convertible versions: the BMW E63 and BMW E64, respectively. The models are badged as the 645Ci and 645Ci cabriolet.

Both versions of the new six currently use BMW's N62 motor, the same powerplant used in the 545i and 745i.

Unlike that of the new 5- and 7-Series cars, the styling of the new 6-Series has generally received a warm welcome from the BMW community—except, largely, owners and enthusiasts of the E24.

In 2005 an M6 version of the new 6-Series will be introduced. It will share the E60 BMW M5's engine and gearbox.
