Now, this being a rear wheel drive E63 it will be faster from a roll than the 4Matic version as it is lighter and only sending power to the rear wheels rather than all four. It will beat the 4Matic version in a roll on race but is the difference so large that in stock form it can keep up with a modified F13 M6? On paper, it is possible as the F12 M6 traps 116 in the 1/4 mile. The stock F13 M6 coupe traps 123 miles per hour in the 1/4 mile in comparison. Yes, the convertible is much heavier at 4,495 pounds.
The E63 AMG S version with 4Matic runs 121.8 mile per hour trap speeds. Let's assume the lighter by about 200 pounds rear wheel drive E63 closes the gap with a stock M6. This being the heavier convertible F12 version of the M6 the E63 should win stock for stock. Is it beating a modified M6 with bolt ons though?
Look at the videos below and come to your own conclusion. It sure looks like the weight penalty of the drop top has a big impact on performance.
