Nurburgring 8.22 mins.
Hockenheim short track in 1:18.6 min

A short summary of that article:

At the Nurbruring some seconds get lost due to the ESP inetracting and taking control even though it was switched off.

On a short track such as Hockenheim the raising tyre temperature causes more and more understeer so that the lap time couldn´t be improved after the first lap.

Nevertheless the parise the agile handling and to power that could make it running fatser than the 250 km/h it is limited to. AMG is considering to remove the limiter on request so that it could hit the 300 km/h bareer.

No problem with the brakes but areodynamic could be improved, at 200 kp/h there´s no downforce at the front and rear axle.

Even though the understeer it can be comtrolled easily and stand 1.15g at the skidpad, the Pirelli P Zero tyres offers enough grip.

Thanks alot for this tracktest. I just wonder why the C55 is faster around "The Ring" than the SLK 55. Better aerodynamics maybe? Or different settings on the ESP?

a friend of my has a SLk55, bought it himself. Damn fine cars, but just not for me.

could be, Sportauto complained on it for SLK55

I think the next car they drive is CLS55 cause not long time ago, Sportauto drove both SLK55, CLKTM and CLS55 at the same time and now they have presented CLK-DTM and SLK55, therefore I belive the next car around Nordschleife is CLS55

Does any1 dare to guess the laptime for CLS55 around Nordschleife? My guess is somewhere between 8.15 - 8.18 min

I dont think you can completely turn off the ESP in any merc. From what i understand, on the SL55 it turns off somethings and then trys to function as an LSD.
