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 they trickle down to 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 not produced a M model for the 7 Series (i.e. an “M7”). However, in 2014 an “M Performance” option became available for the 7 Series. The Alpina B7 serves as the only high-performance variant of the 7 Series.
