Now here's one to stoke a little discussion! PHer BlueEyedBoy is a Z4 M Coupe owner; having been - how to put this politely - shown up by a Vauxhall Astra recently, he is pondering the performance of his M car. Put simply, can the Z4 M Coupe and its E46 M3 counterpart still be considered that fast?
M cars are always a subject of much discussion on PistonHeads, which isn't surprising really given the amount of owners and enthusiasts we have on the site. They're the aspirational dream models, cars to covet but also cars that are realistically within reach for quite a few. So is BlueEyedBoy correct?
Torque has been the main subject of discussion so far, the S54 engine far more reliant on revs for its power than the majority of new turbocharged engines. But does that make it slow? Have we become too accustomed to easily accessible torque? Over to you...
