I've come from a 335i Coupe to a manual M3, the 335i gave me 29 mpg and the M3 22 mpg, the 335i OBC showed also exactly the right MPG as I was getting, however the M3 is about 3 MPG optimistic. Still a lot better than I was expecting.

For me it's not the M3's MPG but the tank range which could do with being longer.
