New for 2006 is a more powerful base V8, which along with it brings a couple of new model names. Gone are the 745 models, replaced by the 750i and 750Li, both equipped with a 4.8-liter, dual overhead cam eight-cylinder engine, with 360 being the magic number for horsepower and torque. Peak horsepower is reached at 6,300 rpm, and maximum torque shows its stuff at 3,400 rpm.

Carried over from 2005 is the V12 fitted into the 760i and 760Li models. Horsepower is rated 438 at 6,000 rpm, and torque comes in at 444 lb.-ft. at 3,950 rpm.

Connected to both engines is a six-speed adaptive automatic transmission with a manual-interactive feature.
