The horsepower race is on, again! BMW's M5 was king of the hill with its hi-revving 507hp V10 until Mercedes released the E 63 AMG with 511hp. Surely only just a few extra horsepower but it still counts as the German premium marques go to battle.

Now, there’s a new kid in town - the twin-turbo V10 Audi RS 6. With its massive 580 horsepower under the hood, it is speculated that Audi has understated the true horsepower figure of 600hp. How long will the RS 6 hold the throne? Well, most likely until the new Mercedes E-Class AMG is released in 2008, however, it seems based upon these latest spy photos that BMW may have a trick or two planned.

Evidence shows BMW is preparing a slightly more evil version of the M5, and this time it appears to be twin-turbos! According to the photographer who snapped this M5 prototype, the engine sound was different from the usual M5. In addition, clearly visible are the extra air intakes cut in the front bumper. However, take a closer look inside the lower air duct openings on the sides of the front bumper and you'll notice a verticle flap which redirects the air flow into what appears to be an intercooler for a turbo.

E quanti cavalli sono previsti?

che cazzate ragazzi........solo ed esclusivamente "horse power wars"

Fanno prima a toglierlo del tutto il paraurti...

A furia di bucarlo di prese d'aria non ne resta poi molto!

In effetti le piccole prese d'aria all'altezza della targa non fanno un bell'effetto .
