The improvements made to the 575 were substantial. The engine has been increased from 5.4 litres to 5.7 litres, the brake discs have been enlarged, the weight has been distributed differently and the suspension has been adaptive. It also features a new interior. Two six-speed transmissions are available, a conventional manual gearbox and, for the first time on a Ferrari V12, Magneti Marelli’s semi-automatic ‘F1’ (sequential) gearbox. The number 575 refers to the engine’s cubic capacity in centilitres, while the ‘M’ is an abbreviation of ‘modificato’ (‘modified’). At the end of its career, the GTC kit would include ceramic brake discs, a differently calibrated differential, firmer suspension and an engine upgrade to 540 bhp.
