Bolt on / tuned E63 M6 S85 V10 versus "bone stock" 2010 C6 Z06 from a 60 mile per hour roll
The C6 Z06 in stock form is a strong car as we all know. It puts out more power to the wheels (~450 versus ~420 for the S85) and also has more torque in a much lighter body. So, it's damn strong. This C6 Z06 is going up a bolt on and tuned M6 though which should be pretty strong namely up top. BimmerBoost has viewed previous bolt on M6 versus stock Z06 videos and the tuned M6's tend to edge it out up top.
This particular Z06 though puts car lengths on the M6. Is it stock? It very well could be if the M6 has a weak tune. Unfortunately, we do not have the full mod list or dyno information on the M6 so this is speculation. But with how easily the Z06 pulls and some mentions from members familiar with it that it is modded one would likely lean toward believing it is not stock.
Regardless, quick Corvette and it gets the win cleanly from the 60 mph roll on.
