BMW 7-Series Getting M750i and 728i Versions in 2013
The car will be called the M750i, and as the name suggests, it’s powered by the same a 4.4-liter twin-turbo V8, the same as a 750i, a 650i or a 550i. 450 horsepower might not sound like much for such a big car, but M Performance division will ensure it handles well.
The M750i will be priced between the 750i and the 760Li, offering xDrive all-wheel drive as an optional extra.
The other new 7-Series coming next year is the 728i, which will be powered by the same 2.0-liter turbo as a 328i, but coupled to a small electric motor to ensure it rival the new Audi A8 Hybrid.
