Stats, S54 cars (sans Z3, sorry)

Road & Track:

M3 Comp Coupe vs Z4 M Roadster vs Z4 M Coupe

M3 Comp Coupe: 0-60: 4.8, 0-100: 12.0, 1/4 mile: 13.4 @ 105.6mph, 60-0 (ft): 114, 80-0 (ft): 196, 200-ft skidpad: 0.88g

Z4 M Roadster: 0-60: 4.7, 0-100: 11.5, 1/4 mile: 13.2 @ 107.9mph, 60-0 (ft): 115, 80-0 (ft): 208, 200-ft skidpad: 0.89g

Z4 M Coupe: 0-60: 4.9, 0-100: 12.3, 1/4 mile: 13.5 @ 103.6mph, 60-0 (ft): 119, 80-0 (ft): 215, 200-ft skidpad: 0.88g

I fail to understand why the Z4m Roadster and the M3 Coupe is faster than the Z4M Coupe and why is the Z4M coupe is the slowest of all three!
