The Maserati Quattroporte Sport GT S's engine
The Quattroporte Sport GT S is fitted with the most powerful engine in the Quattroporte range.
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 not only by modifying the engine’s electronic control parameters, but also through in-depth development of the racing exhaust system, a real jewel of engineering installed on this version.
The system is controlled by air 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 full symphonic sound of a genuine sports car at higher rpm.
Note: EU specs.
