6Series

6Series is BMW's line of grand touring cars that began with the E24 in 1976. It was originally offered as a two-door coupe and convertible, designed to combine long-distance comfort with sporty performance, positioned between the 5 Series and the 7 Series. In the 2010s BMW added a four-door Gran Coupé variant, expanding the lineup to a four-door silhouette while preserving the coupe character.

Across its generations the 6 Series has included several body styles. The first generation, E24 (1976–1989), is noted for its curved lines and the high-performance M635CSi variant. The second generation, E63/E64 (2003–2010), carried forward the grand-touring concept with modern technology and engines including a V10-powered M6. The third generation, launched with the F12/F13 lineup (2011–2018), offered both two-door models and the four-door Gran Coupé (F06), with M6 versions continuing to emphasize performance.

BMW positioned the 6 Series above the 4 Series and below the 7 Series, and offered rear-wheel drive with optional xDrive all-wheel drive. Powertrains ranged from turbocharged inline-sixes to V8s, with the M variants delivering higher output. In many markets the 8 Series was introduced to replace the two-door 6 Series, while the Gran Coupé remained a distinct model in certain markets. The 6 Series remains notable for its design, with early E24 models particularly admired by collectors, and ongoing interest in the M6 lineup.
