The Maserati MC12 is based on the Ferrari Enzo. It is longer, wider, taller, and heavier than the Enzo yet looks infinitely better.
It is the first factory-backed Maserati race car since Eisenhower was in office. It is backed by the factory in the American Le Mans Series.
It debuted last year in FIA GT and now also races in the American Le Mans Series (GT1 class). It won two races last year in FIA GT. Before 2004, a Maserati last achieved victory in 1967 (Cooper Maserati F1) in the South African Grand Prix.
