BMW'sM division has officially announced that the next-generation M5 will be powered by a twin-turbocharged V8. It has long been rumored that this division is moving away from large engines to smaller, forced-induction designs.
In an interview with German publication Auto News, M GmbH boss, Dr. Kay Segler, confirmed this development but didn't give specific details on the engine itself. However, there is speculation that it will be a retuned version of the twin-turbocharged, 4.4-liter V8 used in both the X5 M and X6 M. When used in these crossovers, the eight-cylinder delivers 555hp.
However, sources say that the engine will be tweaked to generate about 575hp for the M5 and the upcoming M6 coupe. Segler implied that BMW was creating two cars in one with the new M5.
He mentioned that one will be a sedate daily driver and the other persona will be an absolute monster on the track. Many believe that some of the configurable engine, transmission, and powertrain controllers found in the M5 are used in the car.
There are also those who think that the M5 and M6 will both receive an F1-inspired kinetic energy recovery system (KERS). The system can restore energy that is typically lost during braking. At the push of a button, the driver gets an added 100hp boost.
The new M5's transmission options have yet to be disclosed but there are old reports that say that the V-8 will probably be coupled with a dual-clutch transmission, allowing the blasting off shifts in a fraction of a second. The existing M5 is offered with a seven-speed sequential gearbox, or a six-speed manual transmission.
