See i wish my e92 M3 was faster, it is slower than my last car with similar power and weight (albeit more torque). I'm holding out for an 18 month old G80 4wd M3, that will be quick.
I find my E92 M3 to be "fast enough". High-revving N/A engines never feel the same as turbocharged cars (even ones with less/similar power) but on UK roads when absolutely "on it", it is easily powerful enough to be consistently in custodial sentence territory and more than enough to be absolutely incredible fun. It absolutely could do with "feeling" faster through more low-down power but then again the M4 feels very traction-limited and isn't as much fun to wring the neck of IMO, despite feeling and being being a very quick car.
