Not that I have done race starts or any of that sort of thing.
I have said this before on different threads. My w212 is first gen model with the 6.2. it feels as quick if not quicker than my previous E55k. The handling is on a different level to that of the barge type w211.
The N/A engine is no slouch, and with its standard torque and hp is a very capable car. For a 2 tonne car in the w212 body it can move even though it's coming on 11/12 years old. My experiences are the diff of the 6.2 w212 is more InTouch with carracter of the 6.2 engine, to that of the 55k and the w211 car. Other factors such as higher rpms on the 6.2 engine play a big part.
I have never had the privilege of driving or owning the 6.2 w211 or s211. I actually would have liked to have tested a few before I purchased my current 6.2 w212.
Reading old threads and articles on the 6.2 vs M113k debate. I was under the impression you would be short changed with purchasing the N/A unit. Well, far from it, there are reasons for owning both. The tuneable side is endless with the M113k. But you still need to get that power down. And in my experiences the W212 chassis does it better, and feels more controlled in doing so.
Yes, to tune the M156 it will cost loads to really up it's anti, but as an off the shelf unit, it's fun, capable, very assured, sounds brutal, and is that jekel and Hyde carracter that can be had to suit different occasions.
Would I do it differently, nope, would I like to have experienced the w211 6.2 after the E55k, yes, I would. Am I happy now with what I currently have, oh YES
