The facelifted E63 AMG and the M5/M6 updated with the Competition Package are basically neck and neck with the edge from a stop going to the E63/CLS63 and the edge from a roll going to the M5/M6. This M6 is not stated to have the Competition Package but that it is shown pulling what is claimed to be a modified E63 raises eyebrows.
Is a stock M6 beating the new 4Matic AMG from a roll odd? Not at all according to MotorTrend's latest results for the E63 AMG S and the M5 Competition Package. The video shows the AMG winning from a stop exactly as it should. However, if this E63 is tuned how is it losing to a stock M6? It should win decisively.
The only logical conclusions are either that the car is not tuned or the tune is incredibly weak. Even a decent tune should put the E63 ahead from a roll. Regardless, the M6 shows just how quick it is from a roll even in stock form. Enjoy the video below.
