YES! It also has something to do with the engine formation, a straight of the same cylinders and roughly same capacity and age (just incase u want to compare a 1950 motor with a 2000) will produce more torque then ur standard V (maybe even if its supercharged too!), it would be the same if an I8 existed, it would have more torque then ur V8, I4's have more torque then ur V4's.
Mercides AMG (the M3 rival one) supercharged their V6 to get it even close to the M3's I6, guess which motor is still better, and which car is faster.
One more thing, is it true that Ford are thinking of a V6 for the Falcon after the AV, fair enough the Aussie 6 is abit old, almost 40 years, and it is a good motor, i think they should get rid of it becuase its showing its age, but why cant they design a new I6? I also hear they're going to front wheel drive, if i wanted a rice blower with front wheel drive i would buy one, is any of these rumours true?
