No I appreciate small displacement engines ( i drive an EP3 afterall and before that a 1.8 DC2, 1.8 MX5 ect.) but M and AMG cars have always been large engines, a lot of power, refinement ect... Not a small 4 pot trying to squeeze every single bhp out of it and probably not making it past 60k miles without a major fault (look at the Fiesta STs and Ecoboosts blowing up recently).
The C63 6.2/6.3 AMG makes an absolutely godly sound, could never compare it to an A45 with it's fake crackles and farts.
That said, I respect the A45, it looks great and is a very capable machine (interior is lovely too). I was just talking more about heritage.
