Why is e55 so much quicker then cls55?
Best in my E55 12.169 (done in perfect cool conditions)
best in my CLS55 12.561 (done in poor hot humid conditions)
I use identical launch technique with both cars
Its not so much the rotational mass of the wheels and it is also not so much a factor of the higher drag coefficient (cd) which does come into play as the car speed gets higher
But the large part of the difference at the drag strip can be attributed to the tire size (which is a factor of wheel size). The lower profile sidewall of the 19" tire cannot absorb and retain the lauch energy the way that the 18" tire can. Lower profile tires might be better on the twisties but they really hurt you on the drag strip
My best 60ft with the stock 18" contis on the E55 was 1.769 (drag is not a factor at this speed)
My best 60ft with the stock 19" PS2's on my CLS55 is 1.912 (which is the fastest 60ft time on dragtimes for a CLS55)
So the CLS is losing around .15 seconds on the launch even before they have got to speed. And then the cd comes into play
I am still hping to get into the 12.3's with my stick CLS55 as the weather here in Florida starts to cool off.

There isn't a lot between them performance wise, but E55 is just pure understated class.

I'm just having fun here guys........the CLS is a sexy beast!!!
Truth be told....if the performance of the CLS was as good as our E's, I' would have considered one!.......Sat in one though and had to hunch my back not to hit the headliner....I'de have a sore neck in 5 minutes that way
Why not a little more headroom..
