BMW’s looking to take on the newest Audi RS6 by producing a boosted version of the M5’s V10 motor, which sources say should make more than 600 HP. The new engine is said to be a development of the twin-turbo 4.4L V8 from the X6M, which makes 564 HP already. With two extra cylinders and the M division’s careful caressing, the newest M5 should be more than a match for the RS6’s bi-turbo V10, which makes 580 HP currently.

In addition, the new M5 should be equipped with the KERS system borrowed from F1, which is short for “Kinetic Energy Recovery System.” Essentially, the new M5 will have regenerative brakes like a hybrid, which will store power that will be available for short bursts via a supercapacitor. Current systems produce a 80 HP boost for a maximum of about 7 seconds. That sounds like a lot of fun. This is a horsepower race that we fully support.
