Totally different engines, you cant compare the 3.2 M3 engine to the V6 of the Golf.
In V6 terms, the Golf produces about as much as it can really..... not many other current V6 models produce as much, or more. Only the Alfa V6's produce more, and thats normally 250hp tops.
It's a big engined Golf with wonderful noise and instant snappy throttle response, combine that with 4wd and a superb chassis setup, what more do people want?
