If you want to know how fast the CL65 is then just watch that race between the ZO6 and the CL65 and the was .7 tenths of a mile run. If only the CL and SL 65's were as light as the E55. The E55 is not light by all means but it is lighter than the two of those cars. According to AMGCENTER.COM they are something like 600lbs heavier. I can only imagine how fast it would actually be if it were the same weight or lighter. It just might be a 10 second car from the factory. Just my thoughts.....

Anyway, how must one interpret this (false) statement about 65's, VMAX and performance package?

SL65, E55T, Pending S65
The SL65 has everything the PP has except the alcantera steering wheel and vmax raised. It also has larger brakes than the PP for the SL55.
I have no idea why the comments were made the way they were. What I do know is that I personally know a couple of people that are in Germany that run their SL65's hard with the limit raised to 300 by AMG and none of them have overheating issues.
I do agree with Maff, the only time I see the needle move is at slow speed in heavy traffic.
Enjoy

When you read about the 03 PP you see "track speed" and "track"used a lot. If the 03 PP is aimed at track use then heat could become an issue because track driving would put much greater demands on an engine/cooling system than cruising the bahn at a constant high speed.

Fair enough.
I'm just wondering this, not to bash on Rob or anything, but It's just that regularly discussions on this forum are being cut short when someone argues "but Rob Allan told it, so there", while other clearly knowledgable people tell otherwise.

This is what I believe is being interpreted wrong about the heat issue with the SL65.
Car and Driver Mag, August 2005
Ironically, our acceleration results are slower than expected, even though the car meets the factory claims for 0-to-60 times. That may be due to the intense heat (over 90 degrees) at our desert test site, where repeated runs had the car's coolant gauge reaching the top of its scale, whereupon the engine computer cuts boost and probably retards ignition spark, too, for good measure. That slows the SL65 right down.
It did the same thing at the Streets of Willow, where we could record only one lap before an identical situation arose. One look under the hood suggests an explanation. There's a tightly packed cluster of hot plumbing under there, and engine-bay airflow is clearly not up to the task of scavenging it. Still, we can't think of anywhere you could use full power for long periods of time in this car in normal circumstances. Except maybe on the autobahn, where high-speed airflow would doubtless cure the problem.
Where the SL65 stood apart from the others was in the quiet, smooth way it goes about its business. The others get in your face. This one plays it cool.
The 65 ran with the GT even under conditions that were not to its advantage. Cooler weather may have given the 65 the top dog spot as far as top speeds and acceleration.

By the way , Bob at Renntech stated that about 20% of the 65's that they work on have shown that the intercoolers are not performing to their max, and that sometimes changing the intercooler if they identify that there is a problem is an option, $600.00.
