"The Maserati MC12 was produced to allow a racing variant to compete in the FIA GT Championship. The car entered production in 2004 with 30 cars produced (five of which were not for sale). A further 25 were produced in 2005 making a total of 50 cars available.

Maserati designed and built the car on the chassis of the Enzo Ferrari but it is much larger with a lower drag coefficient. The MC12 is longer, wider and taller and has a sharper nose and smoother curves than the Enzo Ferrari, which has faster acceleration, better braking performance and a higher top speed. The top speed of the Maserati MC12 is 330 kilometres per hour (205 mph) whereas the top speed of the Enzo Ferrari is 350 kilometres per hour (217.5 mph)."
