It will be quicker because of the shorter final gear ratio (2,82 vs. 2,65).0-100km/h is no fun and overated figure. Lets use a more intresting measurement. How much faster is E63 0-160km/h, 0-200km/h, 100-200km/h in fourth gear than S65? E63 should be quicker I think since its a lighter car.

Anyway, great ride. I'm sure the new powerplant is gonna be an efficient beast.
See for yourself. Engine already tested with CLS63 PP
