AMG on W208 430's query....

[V8Cerbera]

Okay, as previously mentioned, my new baby is a W208 CLK430 cab and appears to have benefitted from the AMG "special equipment", i.e. 17inch AMG rims with 245's on, AMG door sills and the upgraded BOSE stereo... the thing I haave to ask though is, did AMG 430's receive any extra fettling on the engine? The owners manual doesn't seems to mention it in the technical data, only that they had the big wheels, but the manual spec for 0-62 is 7.4sec and having just done a test run with a performancebox (GPS based performance meter), I'm getting a time of 6.3sec....?
Do these versions have any extra oomph? Or is a time of 6.3sec more like what you'd expect rather than the book stat?

I think it’s unlikely that your engine has been tuned by AMG. As I understand it you have a car with some options fitted (or fitted post first purchase by someone else) but I don’t believe AMG ever offered a version of your motor.

You're getting good numbers though

That's what I thought, which is why I thought I'd query the stats and if this 0-60 is actually closer to the mark than what Mercedes put in the book? Anyone else with a 430 care to compare?

The manual I have quotes 6.4sec for the coupé and 7.4 for the cab. I did wonder how it could be so different. Perhaps the 7.4sec time is assuming you have the lid off and are creating a hell of a lot more drag?
