BMW is reportedly planning its first M Performance model using a plug-in hybrid powertrain, according to a BMW Blog report. The car in question will allegedly be a 7-Series dubbed the M750Le – which denotes both the electrified powertrain as a long wheelbase.
Rather than a thirsty V8 or V12, BMW will outfit the M750Le with the B58 3.0-liter turbocharged inline-six coupled to an electric motor. This engine, sans the hybrid system, currently delivers 382 HP in the M40i, but a figure closer to 400 HP is possible for the new plug-in hybrid 7-Series that could be built in short wheelbase guise too.
Combined power could swell to as much as 550 HP and 590 lb-ft (800 Nm) of torque with the electric motor, giving the executive saloon enough grunt to rival even the M760Li xDrive. In addition, BMW will use its latest-gen batteries that offer greater electric range, as well as a more efficient electric motor.
This isn’t the only 7-Series plug-in hybrid being developed, though. According to the same source, a 745LE PHEV is also on the cards with the same electric motor and battery pack as the M750Le, but a slightly less powerful internal combustion engine that could deliver anywhere between 450 and 470 HP.
BMW is looking to reinvigorate its lineup of ‘green’ cars, and hybridizing the 7-Series is certainly one way to do it, although the launch date is, at this point, unknown.
