While the natural reaction is to compare the 1-Series M Coupe to the 135i, BMW has used the original E30 M3 as the inspiration for this car. It shares proportions with the 1988 M3, being just 4.8 inches wider and 1.3 inches longer, with a wheelbase 3 inches longer. Compared to the 135, it the 1M has the same wheelbase and slightly wider track (2.8 inches in front and 1.8 inches in the rear). It’s 11 pounds lighter than the 135i, at 3362 pounds. It borrows a lot of components from the current M3, including its aluminum rear subframe and suspension, centrifugal M variable differential lock, and nineteen-inch wheels.
