Exterior

The design of the new Quattroporte Sport GT S has a sporty emphasis, yet does not compromise on the style and elegance that have always epitomised Maserati’s flagship model.
The designers at Pininfarina have succeeded in their aim of giving the car a sportier edge whilst preserving the integrity of the original design. The new grille is the most obvious exterior change. It is now wider and has vertical slats that echo the GranTurismo, whilst its black finish maintains the original styling cues.
The deeper set grille is fitted to the front bumper, and is framed by the new fog lights and air intakes that have been enlarged to cope with the more powerful engine. The combination of the redesigned bumper and the new grille bestow the front end of the car with an immediate visual impact.
The front light cluster has also been redesigned and features a titanium finish. This underlines the more aggressive Quattroporte Sport GT S, a feeling reinforced by its xenon headlights and LED indicators.
Turning to the bodywork, the sweeping wing mirrors are more aerodynamic. The shape of the body below the doors lends the new model a more purposeful look. In profile, you can appreciate the car’s lowered stance: 10 mm at the front and 25 mm at the rear.
These few millimetres make all the difference. The car appears poised as if on the starting blocks, ready for action with its racier set-up perfectly complementing the new 440 bhp power unit. The car exudes speed even when it is stationary.
The Quattroporte Sport GT S comes with two new types of 20″ wheel rim: Multi Trident rims in light aluminium alloy as an option and seven-spoke light alloy rims that have undergone the ‘Dark Chrome’ treatment.

Interior

The most sporty model in the Quattroporte range also clearly proclaims its character through the style of its interior, using specific materials.
The seats, which are state of the art in terms of ergonomics and comfort, have a stylised M for Maserati on the backs. The central sections of the seats are upholstered in perforated Alcantara, for optimal breathability and a firm support during hard cornering; Alcantara is also used on the side panels, the front armrest, the steering-wheel and the gear lever knob.
The interior finishes on this version are a celebration of technology and workmanship. The material used is the groundbreaking TitanTex, an ultra-lightweight aluminium-coated titanium fibre fabric, made even more special by a specific processing, which gives the interior a high-tech, high-performance look, as well as a shinier, more three-dimensional overall appearance.
The steering paddles, integral with the steering column, have a decorative chromed finish that gives their edges definition: they are also longer in shape, to ensure a good grip even when the steering wheel is on a tight lock. The interior finishes are completed by the exclusive addition of the name of the model in relief on the dashboard.
Aluminium pedals are available as an optional: specially designed for racing-style driving, they provide outstanding grip when the brake and accelerator are depressed and released in quick succession.

Technology

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.

Engine

The Quattroporte Sport GT S is fitted with the most powerful engine in the Quattroporte range.
Capable of 450 HP at 7,000 rpm and a maximum torque of 510 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.

Introduction

Imagine being at the roadside on the Via Emilia – the heart of a region famed for its motoring links – on a cool summer morning. You hear the unmistakable sound of an engine before a powerful car appears. On the car’s grille sits the Maserati badge. The car is a cabriolet. There can be no mistake: it is the GranCabrio.
The name, GranCabrio, evokes Maserati’s renowned traditions and experience, tying the new vehicle to the GranTurismo concept and bringing to life past GranSports. At the same time, the name underlines how much the car differs from every model that has preceded it. The GranCabrio redefines the idea of a cabriolet.
The open-top, four-seater GranCabrio offers the chance to share a fantastic driving experience with those you love, one enhanced by top quality materials, the aroma of prestigious woods and refined leather. GranCabrio is Maserati’s exclusive take on the need to live exciting experiences in company as opposed to the mania of owning things just for the sake of it.
GranCabrio is designed for those who take pleasure from good taste and who appreciate Italian power and elegance. However, they do not want to be limited by using the car just as a couple or not being able to at all because there is a new addition to the family. In the GranCabrio the joy of sharing experiences reaches previously unattainable heights.

Exteriors

The Maserati GranCabrio manages to be both dynamic and elegant. The car draws its inspiration from the GranTurismo, an example of the perfect synthesis of modernity, sensuality and passion.
Created by master coachbuilder Pininfarina, the GranCabrio is characterised by its soft-top roof. This styling bonds the GranCabrio closely with the company’s refined traditions.
When closed, the rear pillar – one that does not, in fact, exist – is mimicked in the hood’s smart, forward-slanting design, giving the GranCabrio the dashing looks of a coupé.
Once open, the Maserati GranCabrio transforms into an astounding cabriolet, free to show off all its sinuous, feline beauty. The vibrant side-on view is accentuated by the reduced ground clearance and long bonnet. A stylish ‘V’ points towards the grille, in the middle of which is a large chrome Trident.
The flanks also feature chrome elements that give the GranCabrio some added gloss. One particularly goodlooking feature is the continuous chrome trim that encircles the cabin and integrates with the third rear stop light.
Towards the back of the car, the triangular light cluster is formed by 96 LEDs with a wide diffuser that further underlines the car’s athletic poise. This sporty feel is also seen in the generous 20” wheel rims that reflect the Trident design.
The shape of the GranCabrio is the result of extensive aerodynamic testing aimed at limiting the drag typical of droptop cars. The GranCabrio boasts a Cx coefficient that is one of the best in its class: 0.35 with the hood up and 0.39 with it down. The spoiler and rear diffuser both contribute to obtaining top draw roadholding.

Interiors

The Maserati GranCabrio is the only real droptop in its class to offer enough space for four adults, seated in an elegant and luxurious cabin. The space inside is much greater than the average for its category and ensures the maximum comfort even for passengers in the rear.
The interior is divided by a central tunnel that distributes the space between the occupants along the car’s length. The dashboard extends horizontally and its upper section features a characteristic ‘V’, a distinctive Maserati symbol.
The GranCabrio’s cabin is easy on the eye and invites you to touch it. Only the finest materials were employed in its build: the leather was handcrafted by Poltrona Frau® and a selection of prestigious woods was used for the dashboard, door panel and rear flank features. The level of craftsmanship and attention to detail can also be seen in the chrome rings that enhance the dashboard switches and steering wheel as well as the Alcantara finish on the back of the steering wheel paddles.
Adding to the on-board comfort is the canvas hood, one made up of three layers to censure excellent acoustic isolation. With the top down and with just two on board, it is possible to minimise interior air flow thanks to the windstop developed specially for the GranCabrio (available as an option).
On the Maserati GranCabrio, the air conditioning has been tweaked to offer the maximum comfort levels both with the top up or down. The system recognises how the car is being used by automatically reprogramming the emissions mixed with air to maintain the set temperature.

Technology

Engine
The engine on the Maserati GranCabrio is an eight cylinder, 4691cc V90° capable of developing 440 hp at 7000 rpm and with a peak torque of 490 Nm at 4750 rpm. The power unit uses the advanced technology typical of all Maserati engines. This allows the declared power figures to be reached, ensures smooth gear changes and a quiet engine.
The timing is actioned by two overhead camshafts per bank and four valves per cylinder controlled by hydraulic tappets. The overhead camshafts on the aspirated side are controlled by a low pressure, continual phase variator, a technical solution that, together with the optimisation of the combustion chamber, allows 82% of the maximum torque from 2500 rpm for a superb overtaking, even in high gears.

Transmission
The Maserati GranCabrio features a six-speed, ZF automatic transmission with a hydraulic torque converter to give extremely fluid gear shifts while maintaining the characteristics of the sporty V8 engine.
The transmission has four modes and is also fitted with self-adapting control that adjusts the type of gear change to the driving style and road conditions.
In Manual mode, gear changes are sequentially made by the driver via the steering column mounted paddles or the gearstick.

Exhaust
The engine noise is emphasised by the sports exhaust managed by the by-pass valve. Pushing the Sport button opens the pneumatic valves if the car is on the move and the engine above 3000 rpm. This means that the engine can be exploited to the full, giving a rewarding engine roar. This becomes even more gripping with the hood down, making the car one with its surroundings.

Chassis
The weight distribution on the Maserati GranCabrio is slightly biased towards the rear with 49% over the front and 51% over the back with the hood up. With the hood down, the front-rear split is 48-52%.
This set up was achieved by stationing the engine behind the front axle and results in true and predictable handling that makes driving easier and renders the car more stable.
The new loadbearing chassis is constructed from a blend of materials with an eye on keeping the weight down. The framework is made from toughened steel apart from the bonnet and front bumper bar, in aluminium, and the boot lid in heat treated plastic that uses Sheet Moulding Compound technology.
The chassis was developed to provide maximum stiffness even without a roof. The result is that the Maserati GranCabrio is able to offer the same driving pleasure as any quality closed-top car.

Suspension
The Maserati GranCabrio is fitted with the electronically controlled Skyhook suspension as standard. This system employs dampers with an aluminium body that continually adjust the damping. This solution means that the set up adapts instantly to the driving style and the road conditions to offer the utmost in on-board comfort.
The Skyhook system acts by using acceleration sensors that detect movement on all four wheels and the body. A control unit processes the data it receives from the sensors, analyses the driving style and road surface and instantly adjusts the dampers accordingly via their proportional valves.

Electronics
The car’s already superb dynamic handling is constantly monitored and optimised by the Maserati Stability Programme (MSP). The MSP kicks in to correct even the hint of a skid by reducing torque. Working with the ABS and EBD, the system stops the wheels locking under braking, distributes the braking between the front and rear axles. It also prevents the wheels spinning on low grip surfaces when accelerating or climbing (ASR and MSR).

Hood
The Maserati GranCabrio’s canvas hood was a technological as well as aesthetic choice. The soft top solution means a lower centre of gravity because the bottom of the car is heavier. This enhances the car’s dynamic handling.
The hood weighs only 65kg and the materials, mechanism, its operation time and stowage are all top quality. The GranCabrio transforms from a splendid coupé into a cabriolet in just 28 seconds if the car is travelling up to 30 km/h.

Safety

The Maserati GranCabrio is on a par with the highest safety standards in its category thanks to the adoption of innovative active and passive safety features.

Active safety
The dynamic handling on the GranCabrio is assisted by the electronically controlled Maserati Stability Programme (MSP). The technology was developed to optimise the driving dynamics and safety when on the move. The system is supervised by a series of sensors that pick up any unsteadiness to adjust the brakes and engine and provide ideal traction.
The high performance brakes on the GranCabrio were built by Brembo and feature four self-ventilating drilled discs. The 360 mm front brakes make the most of co-cast disc technology (cast iron for the braking surface and an aluminium hat). This solution, teamed with callipers actioned by six pistons in a single aluminium block, ensure unbeatable stopping power and are highly resistant to fade even under intense use.
MSP works in harmony with the ABS to stop the wheels locking under braking, and EBD, to distribute the braking between the front and rear axles.
The Electric Park Brake (EPB) replaces the traditional mechanical handbrake with an electronic control on the central tunnel. The EPB system is engaged automatically when the engine is switched off and is only deactivated when the accelerator pedal is pressed. EPB also plays an important role in terms of safety as, in an emergency, it acts on all four wheels and can be employed with the vehicle in movement, without compromising stability, until the switch is released.
The Brake Assist System (BAS) has been introduced on the Maserati GranCabrio to improve safety. Thanks to a dedicated sensor, BAS recognises panic braking by measuring the speed at which the brake pedal is depressed and clamps the brake pad to the disc before the driver even begun braking. This shortens the stopping distance in emergency situations.

Passive safety
The Maserati GranCabrio is fitted with new generation airbags, using the intelligent technology first employed on the Maserati Quattroporte S. The passenger side airbag, with its ‘Low Risk Deployment’, adapts the intensity of its inflation in crash situations to the size of the occupant.
New head and chest airbags set in the front seats provide protection from side impacts while seatbelts are equipped with the latest pre-tensioners and load limiters to securely contain all four occupants.
The main introduction in terms of passive safety is the extendable roll bars set behind the rear seats. The roll bars are hidden by the hood cover and are activated in just 190 milliseconds when needed.

The extendable roll bars were developed to offer occupants the maximum protection both with the hood raised or tucked away. A Maserati copyrighted technical solution allows the roll bars to extend by shattering the rear window without any risk for the occupants.

Personalisation

The GranCabrio introduces new personalisation options to the Maserati range
Maserati offers a personalisation programme that is unlike any other in the world. This programme has been developed with the objective of allowing each client to create a made-to-measure car. Such a level of exclusivity is a source of pride for Maserati, a small company able to devote the highest levels of care and attention to every car it builds and guarantee the client a wider range of finishes than its competitors.
The personalisation options on the GranCabrio have been enhanced by the soft top hood, available in six colours, and by the introduction of two new Poltrona Frau® tints, Bianco Polare and Blu Profondità. The colours are available on the Maserati range for the first time and were developed for their harmony with the exterior colours and hood.
The dashboard, door panels and rear side panels are available in the new ‘Dark Chrome’ standard colour but it is also possible to choose from various lacquer finishes or precious woods, among them Carbalho and Moonwood.
In terms of the mechanics, there are two colours for the wheel rims (Silver or Grigio Mercuri) and six colours for the brake callipers.

The Car Configurator
Maserati provides excellent support in configuring even the smallest details on the GranCabrio. The Car Configurator gives the client the opportunity to create his ideal car online and ensure that the combination he has chosen, including the colour of the leather and materials, the finish of the headlining, the stitching and the carpets, is really what he wants.

Atelier Maserati
Visitors to the Modena headquarters can make the most of expert help in creating their dream car by using the Atelier Maserati, just like they would for a suit styled by a master tailor.
The Atelier provides examples of the available options for the interior thanks to a special table showing colour samples of the leathers, the carpets, the stitching and the finishes. Clients can also browse colours for the interior and exterior and feel for themselves how the different materials combine with one another, allowing them to check the options selected on the Car Configurator.
