BMW has not graced us yet with an M7, however, it continues to work with Alpina to give us the best alternative, with their new B7 xDrive.
The third generation of the full-sized luxury sedan uses a 4.4-liter twin-turbo V8 engine that delivers an impressive 600PS (hp), between 5,750 and 6,250rpm, and 590lb-ft (Nm) of torque, available from 3,000rpm.
Story in development.
