The BMW 750i xDrive was a variant of the F01 7 Series that was introduced for the 2009 model year. The 750i xDrive was offered on the 7 Series' short wheelbase and was only built in a sedan body style. These luxury cars were initially powered by BMW's N63 engine, which was a 402hp twin-turbocharged 4.4L V8, but from the 2013 model year, this engine was given a technical update which saw power increase to 444hp. From launch until the 2013 model year, a 6 speed automatic transmission sent drive to all four wheels, but after 2013, an 8 speed automatic was used. Production of the F01 BMW 750i Drive lasted until 2015.
