As with the most sporty GranTurismo in the range (the GranTurismo Sport), the GranCabrio MC also adopts the new 4.7-litre V8 engine, which delivers 338 kW (460 HP) together with substantial torque of 520 Nm at 4750 rpm. The pistons, positioned at an angle of 90°, are made of reinforced, hardened aluminium, as is the engine block. The crankshaft, with five-point balancing, is made of high-strength steel. The timing system, with a system of two chains per bank, features dual variable valve timing. The new power unit, in combination with the MC Auto Shift transmission, is now able to propel the GranCabrio MC, in closed soft top configuration, to a top speed of 289 km/h with acceleration of 0 to 100 km/h in 4.9 seconds.
