In the new BMW X7 M60i xDrive, the 48V mild hybrid system connects with the updated 4.4-liter V8 engine with M TwinPower Turbo technology. The new V8 utilizes the thermodynamic benefits of a cross-bank exhaust manifold, bank-symmetrical turbochargers, and external engine oil cooling. In addition, a reinforced crankshaft drive, further developed turbocharging with a blow-off valve, a new oil pump and a weight-minimized oil sump all play a role in increasing the engine’s efficiency.
The combination of the engine and the electric motor integrated into the 8-speed Steptronic Sport transmission gives customers the twin benefits of optimized response and power delivery under acceleration and increased efficiency thanks to adaptive recuperation at up to 0.13 g. The controlled intervention of the electric motor also noticeably increases comfort levels when the Auto Start Stop function cuts in and in idling and coasting situations. The coasting function with deactivated combustion engine comes into play when the Driving Experience Control mode ECO PRO is selected.
With its output of 523 bhp and peak torque of 553 lb-ft, the eight-cylinder engine propels the X7 M60i from 0 to 60 mph in an estimated 4.5 seconds. The relentless power development of the V8 engine is accompanied by an emotionally rich soundtrack from the standard-fitted sports exhaust system.
