The 7-Series is BMW's technology flagship, and by most measures it's the most luxurious model in the German automaker's lineup. It offers a wide range of powertrain possibilities, standard and long-wheelbase versions, a green ActiveHybrid option and a high-performance Alpina model. Even at its simplest, the 740i is one of the most athletic-feeling large sport sedans, while well-optioned 750 and 760 models offer some of the world's leading convenience and accident-avoidance technology.
