The Maserati Quattroporte Sport GT S

Here is the Maserati Quattroporte Sport GT S, a new high-performance flagship for the manufacturer's Quattroporte range.

It has a re-mapped engine control unit, increasing the 4.7-litre V8s power by 8bhp to 433bhp, a new sportier-sounding sports exhaust and revised gearbox software.

The Sport GT S also features tweaked shock absorbers, stiffer springs and a lower ride height.

There are visual changes to help differentiate the Sport GT S from the standard S model. These include a black grille with red accents for the Trident logo, black rather than chrome finishing around the doors, and twin oval tailpipes and metallic-finish headlights.

The Quattroporte Sport GT S is due to be unveiled at the Detroit motor show in January.

Prices and an on-sale date for UK cars are yet to be confirmed.
