The M3 is noticeably smaller than the A4. I expected an A4 sized car. I would suggest that the M3 stay the size that it is ( or larger ) so that there can be a smaller more affordable Model out there......IE M1.5.
The Model 3 is very comparable in size to the A4, give or take a few inches. In fact, considering the assumptions of the wheelbase (which is a good indicator of passenger cabin space), the interior space might be more comparable to the size up A6/ MB E-Class. The assumed wheelbase is longer than C Class, 3 Series, A4, Infiniti Q50, Honda Accord, Nissan Maxima, even the Chevy Impala! The Model 3 looks like it'll have tremendous packaging for its class and size.
