The BMW 7 Series is a full-size luxury sedan manufactured and marketed by the German automaker BMW since 1977. It is the successor to the BMW E3 "New Six" sedan and is now in its seventh generation. The 7 Series is BMW's flagship car and is only available in a sedan bodystyle (including long wheelbase and limousine models). It traditionally introduces technologies and exterior design themes before other models in BMW's lineup. The first generation of the 7 Series was powered by straight-6 petrol engines, and following generations have been powered by inline-4, straight-6, V8 and V12 engines with both natural aspiration and turbocharging. Since 1995, diesel engines have been optional in the 7 Series. Unlike the 3 Series and 5 Series sedans, BMW has offered a nonpureblood M variant, the BMW M760 6.6L V12 (at the time the most powerful BMW ever made, not to be confused with BMW 760 6.6 V12 which does not offer the same performance). The Alpina B7 (G12) serves as one of the high-performance variants of the 7 Series. From Wikipedia
