The Maserati Quattroporte Sport GT S has a new side personality which makes it turn into a roaring beast at the touch of a button. The 4.7-litre V8 churns out 324kW (440hp).

Maserati is ready to sell the Quattroporte Sport GT S to the salivating potential UK buyers. The Quattroporte Sport GT S was unveiled at the 2009 North American International Motor Show in Detroit. Sporting a 4.7-litre V8 engine, the luxury sports sedan benefits from several tweaks that its makers say will sharpen its sportiness and help it in delivering a dynamic drive.

The V8 now makes maximum power of 324kW (440hp) at a wheezy 7,000rpm because of a new sports exhaust system. Peak torque is 490Nm achieved at 4,750rpm. Mated to the engine is a 6-speed automatic transmission with a manual drive mode which is controlled by the driver through paddle shifters integrated with the steering wheel. Using the MC Start Strategy launch control, the Sport GT can blast off from 0 - 100km/h in 5.1 seconds.

Two character modes are available. The one is the Normal mode in which the exhaust valves are closed. This mode redirects the exhaust gases to travel a longer path so that by the time they reach their destination they have lost much of their fizz and throaty sound. Then there is the Sport mode which is actuated through a button. This mode opens the valves that were closed under Normal mode and the gases head directly out to give the car a proper sports sound.

To put an even wider smile on the driver's face, the big Maserati offers a free throttle blip with each down-shift when using the Sport mode. Better grip and cornering ability are created by, among other things, springs whose stiffness has been increased by 30% at the front and by 10% at the rear. The Quattroporte Sport GT S runs on 20-inch wheels that come in a couple of design shapes.

Luxury features include an Alcantara and leather interior, aluminium sports pedals and a carbon fiber interior trim.
