The GT version of the 456M was equipped with a six-speed manual gearbox while a four-speed automatic came with the GTA. 0 to 62-mile per hour acceleration for the Ferrari 456M GT was rated at 5.2 seconds. Acceleration times for the version of the 456M equipped with an automatic transmission was slightly slower measured at 5.5 seconds. Four-wheel disc brakes behind the Ferrari 456Ms 17-inch aluminum wheels and a rear self-leveling suspension system allowed the 2+2 passenger sports car to achieve steady handling. Able to fitted four occupants, Connolly leather covered the seating inside the Ferrari 456M. Dual front airbags, power windows and a Becker stereo system was included standard.
