That isn't the worst of it, word is Mercedes will be using an ECU that also will be tuneable. Someone happened to tell us that a last minute decision was made to not use the Siemens/Continental SE controller and stick with Bosch which means a ton of power will be on tap. If this wasn't bad enough for BMW fans who are going to be playing around with BMW anti-tuning measures and less displacement, Mercedes plans to put their 4.6 liter twin turbo V8 in most models as well to replace the 500/550's. Who says the horsepower war is over? Mercedes seems intent to blow BMW away and I would personally like to thank them for doing so, maybe it will wake BMW up.
C63 Black Series
A prototype has been spotted running at the AMG Academy in Europe. Fitted with a cage and matte black paint the car was testing with an SLS. Most likely, it will share the top end of the SLS motor. Will it come to market? It would sure seem that they are serious about it.
Where does this leave BMW?
Good question, the next gen M5 and M6 will be strong performers taking on the best MB has to offer. However, what about the rest of the lineup? The N63 4.4 TT V8 has the Mercedes 4.6 liter twin turbo V8 covered but the M3 and 3 series are going to struggle against such a formidable opponent.
