The 4700 cc Maserati V8

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 433 HP at 7,100 rpm and a maximum torque of 361 lt-fb 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-style exhaust system, a real jewel of engineering installed only on the Sport GT S 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.
