MASERATI QUATTROPORTE SPORT GT S

The Maserati Quattroporte Sport GT S’s gearbox, chassis and suspension

Gearbox

The new Quattroporte Sport GT S is equipped with the MC-Auto Shift software package for racing-style control of gear changes.

In "MANUAL MODE" the driver controls gear shifts directly, and changes are permitted up to the redline on the rpm counter. For the most enjoyable, highest-performance driving experience, an electronic gear shift indicator in the middle of the dashboard tells the driver when it is the ideal timing of the gear change; this system, which enhances the pleasure and satisfaction of the driving experience when truly putting the car through its paces, is complemented by “Trofeo” style extra-long paddles behind the steering-wheel, ergonomically shaped for easier gear changes on the most demanding roads.

In AUTO SPORT mode, the gear shift control software activates the MC Start Strategy function. This function allows controlled starts enabling the car to accelerate from 0 to 100 Km/h in just 5.1 seconds, instead of 5.3 seconds.

MANUAL SPORT and AUTO SPORT modes both also provide electronic heel and toeing during down-shifts; this, combined with the Quattroporte Sport GT S’s other characteristics, make this saloon car capable of unprecedented sporty performance.

Suspension
The Quattroporte Sport GT S is fitted with the single-setting racing-style suspension system: developed to further enhance the car's handling, it makes its steering extremely sensitive and responsive.

The additional stiffening of the suspension by 30% at the front and 10% at the rear, together with a reduction in ground clearance of 10 mm on the front and 25 mm on the rear axle respectively, provides a substantial reduction in load transfers and more effective traction control during direction changes.

Steering
The electronic power steering is direct and precise at speed so the driver knows what the car is doing. At the same time, it is light and easy to use at lower speeds and when manoeuvring.

Weight distribution
The Maserati Quattroporte Sport GT S’s weight distribution is unique in its category with a slight bias towards the rear end (49% front and 51% rear). This split transforms the luxury saloon into a car where performance is favoured and that rewards the driver with its superb handling. This set up was achieved by shifting the engine behind the front axle to maximise traction and acceleration while also making the car stable and perfectly balanced.

Brakes
The new Maserati Quattroporte Sport GT S comes with a high performance braking system developed by Brembo. The 360 mm brake discs benefit from dual-cast technology: cast iron for the braking surface and an aluminium hub. This set up takes advantage of the consistent performance of cast iron at high temperatures and from the lightweight aluminium.

The six-piston callipers, of different diameters, are in a single aluminium block. These keep their shape better than two piece calliper sets and offer unbeatable stopping power.

The system is completed by the ABS, that stops the wheels locking under braking, and EBD, that distributes the braking force between the front and the rear axles; both systems are integrated into the Maserati Stability Programme (MSP). This solution offers excellent performance both in terms of stopping distance and resistance to brake fade, even under intense use. The Quattroporte Sport GT S’s brakes are always prompt in responding and live up to the standards you would expect from a Maserati saloon.

Lights
The new Quattroporte Sport GT S uses front and rear lights that have been developed to offer only the best in each individual function. The use of LEDs makes a big impact on the car and is one of the elements that link this model to the Maserati GranTurismo.

The most important lighting functions have been improved. The front xenon cluster now boasts the Adaptive Light Control system. This produces a brighter and clearer beam compared to conventional bulbs. The lights also automatically track the movements of the steering wheel so that the beam points to the inside of a curve (up to a maximum of 15º). For safety reasons, when the car is travelling above 120 km/h, the system returns to a traditional fixed position.

The Daytime Running Light function is a useful addition and is made up of ten LEDs set along the bottom edge of the headlight. The indicators catch the eye and the front headlights are memorable for their side-marks that merge flawlessly with the outside edge of the car, with the wiper forming part of the cluster. The fog lights employ an altogether different set up and are located in the bumper to ensure a wider beam.

This system is also used in the rear with 34 LEDs making up each light. This technology was employed because LEDs illuminate more quickly and produce a more intense beam than normal bulbs. They last longer, consume less energy and their performance does not dip over time.
