Which one wins if you pit the new BMW M6 against the Audi S6, then versus the powerful Mercedes C63 AMG Coupe?

The M6 certainly has more power than its two rivals since it offers 560 hp from its 4.4-liter biturbo V8 engine compared to the 450 hp produced by the 4.0-liter biturbo V8 engine of the S6 and the 451 hp coming from the 4.0-liter biturbo V8 of the C63. Therefore, a safe bet would be with the M6.

Now, what if these cars have been tuned to the teeth? The game of each car would definitely be amplified to bring about unexpected results.

In the video below, the M6 remains as being the most superior among the three in terms of power with its 800 hp output provided by the Evotech Stage 2 tuning kit. The C63 follows with its 700 hp stemming from the package installed by Weistec. The S6 had a custom stage 2 tune to push its output to 560 hp.

Check out the video below, which was posted by DragtimesInfo on YouTube, to see which car stood out among the three:

Result (Spoiler Alert)

The first part of the race placed the BMW against the Audi. The more powerful engine of the M6 prevailed over its more agile rival.

The tide shifted though when it was the Mercedes’ turn. Despite the 100 hp advantage of the M6, it was beaten by the C63 in a very convincing fashion.
