The consistent advances achieved under the banner of BMW Efficient Dynamics also benefit the new diesel engine for the BMW 7 Series. In the new BMW 740d xDrive, an extensively updated combustion engine teams up with the latest 48V mild hybrid technology featuring an electric motor integrated into the eight-speed Steptronic transmission. The result is maximum output of 300hp (generated by the combination of the engine with up to 286hp and the integrated electric motor with up to 18hp and peak torque of 494 lb. ft. of torque (generated by the combination of the engine with up to 494 lb. ft. of torque and the integrated electric motor with up to 147 lb. ft. of torque.
The latest generation of mild-hybrid technology ensures the additional power comes on tap with particular immediacy and the level of recuperation is high, so as to improve efficiency. The electric motor is integrated – together with its power electronics – into the housing of the eight-speed Steptronic transmission, where it also assumes the role of a crankshaft-driven starter generator. The rapid power delivery of the electrified drive system enables acceleration from 0 to 62 mph in 5.8 seconds. Added to which, the high-precision interplay between the combustion engine and electric motor enhances the efficiency and smoothness of the drive system, making it ideally suited for service in the new BMW 7 Series.
