Actually e9X M3 is 20/mpg. GT3 is roughly the same at 21/mpg. However there's no way u can drive the GT3 smoothly and comfortably in the city compare to M3 engine. And yes the GTS is higher at 27/mpg but max rev is only at 7500rpm.
But honestly the GT-R had higher mpg then M3. But only if driven like a grandma. Once driven normally or even remotely fast, it consumes much more gas.
