Well iam talking about D mode. The older one does in 14 seconds in D mode!
Cuz i really dont remember abt older one having S option. It should be even quicker in S.
And having 3 cylinders means lower power
S63 AMG is V8 and has 6.3l twin turbo engine, where as
S65 AMG has V12 6l twin turbo and is way faster then S63.
So number of cylinders do matter. If you cannot digest the theory of german cars then take the example of Mark X 2.5 and Accord 2.4
Mark X is way faster then accord since it has 6 cylinders where as accord has 4.
