The 7 Series was facelifted for 2006 with a restyled front and rear and a larger range of engines.
The 7 Series featured BMW's first of a kind iDrive system, consisting of a video screen in the dashboard and a controller mounted on the center console that is used in a similar way to a computer mouse. Using a system of eight menus, most of the car's climate, audio, navigation, suspension and communication settings are controlled via iDrive.
"Active" Seat continuous passive motion technology was made standard equipment on the 750/760 models and included in the Luxury Seating Package with heated and ventilated seats for driver and front passenger.
The 4.4 L V8 was replaced by a 4.8 L unit producing 367 hp and 361 lb·ft (489 N·m). The new model with the enlarged engine is now known as 750i and 750Li (for the long wheel-base model). The 750i and 750Li replaced the 745i and 745Li in all world markets. As before, a six-speed automatic transmission with Steptronic is standard on all models.
