The BMW 6 Series is a series of luxury grand tourers produced by the German automaker BMW. The first was the E24, being derived from the first generation 7 Series, the BMW E23. The E24 was launched in 1976 to replace the 3.0CS & 3.0CSi (E9). In 2003, 14 years after production ceased, BMW released the all new E63/E64, which was available as a coupé and convertible, based on the chassis of the E60 5 Series sedan.
Models were the 645Ci (later replaced with the 650i) and the 630i, while the highest performance model is the BMW M6. The third generation F12 and F13 6 series was released in 2011 for the 2012 model year, sharing a platform and some engines with the 7 Series (F01) and 5 Series (F10), and introducing a four-door coupé (fastback sedan) style, known as Gran Coupé. The BMW 8 series is sometimes regarded as the spiritual successor to the E24 6 Series, being also available as a “CSi”, however it had a substantially higher price point and performance than the preceding 6 Series.
