The Maserati Quattroporte Sport GT S MC Sport Line's engine
Capable of 440 HP at 7,000 rpm and a maximum torque of 490 Nm at 4,750 rpm, it raises the car’s performance to unprecedented levels.
These figures have been achieved by not only modifying the engine’s electronic control parameters, but also through in-depth development of the racing-style exhaust system, a real jewel of engineering installed only on the Sport GT S MC Sport Line version.
The system is controlled by pneumatic valves that open in SPORT mode to reduce back-pressure in the exhaust; this increases the maximum power available, and creates a throaty roar at low engine speeds and the full symphonic sound of a genuine sports car at higher rpm.
