BMW M 635 CSI grey

(from Wikipedia, the free encyclopedia)  BMW 6 Series refers to two generations of automobile from BMW, both being based on their contemporary 5 Series sedans. The first was the E24, launched in 1976 to replace the 3.0CS & 3.0CSi (E9). The BMW 6 Series returned in 2003 after a 15-year absence from BMW's model lineup. That year, BMW released the all new E63/E64 which was available as a coupé and convertible. Models were the 645ci (later replaced with the 650i) and the 630i. The highest performance 6 series is the BMW M6. The third generation F12 and F13 6 series is scheduled for 2011.
The original 6 Series was the successor to the E9 coupés, namely the 2800CS, 3.0CS and 3.0CSi. The new E24 chassis was safer than that of the E9, meeting new United States federal crash and rollover standards. The original 6-Series was first launched in August 1976. This car had a 3210 cc engine with 197 PS (145 kW). In 1980 debuted the 635CSi, with a 3453 cc SOHC, 218 PS (160 kW) engine and a top speed of 222 km/h (138 mph). The 635CSi could reach 100 km/h (62 mph) in 7.4 seconds. A luxury version, known as the L6 arrived in 1987 with leather headliner and trim and other accoutrements.
In 1983 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, or M6. This had a DOHC 24-valve 3453 cc, 286 PS (210 kW) engine, taken from the BMW M1 with a top speed of 255 km/h (158 mph). The M6 reached 100 km/h in 6.2 seconds. The M6 also had improved suspension, brakes, and a close-ratio manual transmission.
