Under the Hood
The 528i has a 240-horsepower, 3.0-liter six-cylinder, while the 535i gets a 300-hp, turbocharged 3.0-liter six-cylinder. The 550i has a twin-turbo, 4.4-liter V-8 that makes 400 hp. All three use a new eight-speed automatic transmission; the 535i and 550i also offer a six-speed manual.
BMW's Adaptive Drive system comes with the Sport Package. It includes Active Roll Stabilization, which attempts to actively counter body roll, as well as an adaptive suspension and customizable settings for both the drivetrain and suspension.
Optional Active Steering varies the steering ratio to render easier turning 
at low speeds and stable handling at high speeds. Toward those ends, the system 
also alters rear-suspension geometry to effectively steer the rear wheels a few 
degrees, depending on the situation. Optional adaptive cruise control, 
meanwhile, now includes full stop-and-go capabilities to manage heavy traffic.
