Yes, sorry. I mis-typed the wrong key.

It's all about the first 60' and 330'. Your 60' times are exactly the range that I am getting in my E500.

You need to get those down below 2 seconds in order to really move your times forward -- 1.8 or 1.9 would be optimal. Your car is achieving its good times solely on the mid and top end speeds -- a testament to its strength. But what you need to do is focus on off-the-line technique. Even small (0.1 second) improvements here will mean larger improvements at the end of the run. If you are able to get a 1.9 second 60', I'll bet you'll be at the 13.0-13.1 range at the end of run, possibly lower.

My friend Dan Smith, who owns the "Silver Bullet" which is the world's fastest known 300SEL 6.3, regularly obtains 13.6-13.7 times and he is in the 1.9 second range.

It's all about exploding off the line. That should be your focus. In a car such as the AMG 55s or the E500, after launch you just hold on for the ride. The launch is the gating factor to the lowest times.

Cheers,
