The 7 series continues its tradition as BMW's flagship luxury sedan. The bold exterior styling is a departure from previous generations but has worked well with consumers. The 745 features a 325hp V8. A rare V12 engine option is available in the 760 model (at a steep price premium). This is a large, heavy car with a technological tour-de-force including the iDrive system which centralizes navigation, HVAC and audio system controls. The L models are the extended wheelbase version adding extra back-seat leg room.
