Not really. You get more of a 0-20 benefit. Ie the traction to get going. Once traction is achieved the s drive wins hands down. Some site had more measurements and the s drive was quicker to 100 usually even though the 60 was reached by x first. It's all academic anyway as the differences you're talking about are small compared to human factors.

Maybe the x drive just has better traction coz its a bit heavier?
