I try and add a qualified subjective statement then....
I've driven a few big engined cars (TVR , Merc AMG), some fine handling cars (S2000, Impreza). .... and all i can say in comparison the RS4 does not feel that fast. However i am wrong

as im keeping it because even with its tight 1K miles engine, in the real world it really is that quick. It hides the power too well and only the speedo tells me how quick it had suddenly become.
I guess rather than say its not that quick, you could actually say why does it not have that feel of a push in the back . My guess is the its delivery of power / torque hides it so smoothly.
Also on this power bhp number, i have given up on cars having a number as i was regulary disappointed i..e TVR 5.0 Grifftih quoted at 340bhp, delivering 286bhp.. I now just take all the info in

drive the car and makes me decision.
So this car is luxury, and im looking forward to exploring how it develops ..and an ECU remap...
