I've gone simple here and assumed a constant torque curve...this is a little bit of a stretch in 1st, but probably ok for the others given the small power band they operate within.

This uses kerb weight plus driver and
SLK32 rear wheel dimensions 17/245/40 = 1972mm circumference and 636mm diameter
....For the SRT6 19/255/35 = 2077mm circumference and 661mm diameter.
Interestingly enough - these larger wheels extend the SRT6 times out by 0.33 seconds over the SLK32 due to the 4% torque reduction at the wheels....

If I've made a yn errors or you think this is absolute crap - I'm sure you'll let me know.....


oh...BTW the other reason I was doing this was to work out how a 790Nm SLK55 Kleemann (1650kg - 3650lb) monster could actually get power to the road....

L8tr - slight change to the calc sheets and added SRT6 v SLK32 for the different wheel diameters.
