740i and 740Li models get a 315-horsepower, 3.0L inline 6-cylinder engine and an 8-speed automatic transmission. The all-aluminum engine has twin turbochargers, variable-cam technology and direct injection, all of which help it produce strong torque output at low revs--a full 330 pound-feet from 1,600 rpm. These models now feature available xDrive, which helps improve on-the-road traction and stability and normally sends 60 percent of power to the rear wheels.
BMW 750i and 750Li come powered by a twin-turbocharged 4.4L V8 making 445 horsepower and 480 lb-ft. At the top of the lineup is the flagship 760Li, with a 6.0L V12 engine making 535 horsepower. Both 750s and the 760Li utilize the 8-speed automatic transmission.
Two other models cater to very specific crowds, radically different from each other. The Alpina B7 gets a special 500-hp, twin-turbo version of the V8, huge 21-inch wheels, and Dynamic Damping Control with ActiveRoll Stabilization, an adjustable suspension system designed to bring the handling benefits of a high-performance sedan without the harsh ride. There's also an ActiveHybrid 7 model that combines the 3.0L twin-turbo inline-6, 8-speed automatic transmission and electric motor system with lithium-ion battery technology, enabling zero-to-60 acceleration in just 5.6 seconds.
All 7-Series models come with an auto stop-start system and a Brake Energy Regeneration system that helps save energy by managing the alternator to charge more when coasting or braking.
The 7-Series also has a host of electronics that not only help increase safety and stability but help the 7-Series drive like a smaller sedan. xDrive models come with Hill Descent Control, which can help keep speed within a set speed between 6 and 15 mph on very steep, slippery (snow-covered or icy) inclines. There's also an Integrated Chassis Management system that individually applies the brakes and throttle individually and helps xDrive-equipped cars handle better. All 7-Series models come with an excellent double-wishbone front and multi-link rear suspension, bringing a very responsive feel without ignoring ride comfort. Long-wheelbase (740Li and 750Li) versions come with a self-leveling air spring system for heavier loads, and back-seat space in those vehicles is vast. The front seats in all 7-Series models are firm but long-distance comfortable and very adjustable.
