The M coupe has a static structural stiffness of 16,400 Newton-meters per degree of twist, which is 2.6 times as twist-resistant as the roadster. BMW claims this makes the structural stiffness higher than any other model it has ever produced. Dynamic stiffness is rated at 29.2 Hz, the same as an E36 M3 coupe.
