THE MASERATI QUATTROPORTE RANGE
Maserati – Excellence through Passion
For over 90 years, Maserati has remained true to the principle of ‘Excellence through Passion’, and today is synonymous with the ultimate in high performance, hand-crafted, prestige automobiles. No other car company has a more dedicated and enthusiastic workforce: everyone involved in the manufacturing process treats each vehicle as an expression of their individual skill and dedication. Located in state-of-the-art facilities in the Italian city of Modena, Maserati produces the finest examples of automotive art – stunning creations that have won over thirty major international awards in recent years.
Technology – Purity of Purpose
The Maserati Quattroporte is an uncompromising grand tourer, with advanced technology that confirms its role as the flagship of the Maserati range. Winner of 28 major international awards, its prodigious power, inspirational handling, and sumptuous luxury provide an unparalleled driving experience.
The Maserati Quattroporte is available in two versions: Quattroporte Automatic and Quattroporte DuoSelect. These differ markedly in character – the Automatic delivers a relaxed and effortless drive, whilst the DuoSelect offers a sportier, more involving experience. Both the Quattroporte Automatic and the Quattroporte DuoSelect are available in Executive GT and Sport GT versions.
Engine – 400HP V8
For over 90 years, Maserati has produced some of the worlds most magnificent engines – the Quattroporte’s all-alloy, quad-cam, 32-valve, 4.2 litre V8 being just the latest example. The crankcase and cylinder heads are made of a special heat-treated aluminium silicon alloy, whilst the balanced crankshaft is in tempered steel and runs on five main bearings. The 90° V8 also features two chain-driven camshafts per bank with four valves per cylinder, a Bosch ME 7.3.2. engine ignition and fuel injection system, and a ‘Drive by Wire’ electronic accelerator. Smooth, reliable and refined; the Quattroporte’s mighty V8 delivers a prodigious 460 Nm of torque at 4250 rpm.
While having the same maximum power, the V8 has different technical features and set-up depending on the version:
Quattroporte Automatic (with blue cylinder head covers): wet sump, for more gradual and progressive power delivery.
Quattroporte DuoSelect (with red cylinder head covers): dry sump, for more instantaneous and prompt performance.
Transmission – Automatic or DuoSelect
Automatic: In keeping with its role as a luxurious grand tourer, the Quattroporte offers a six-speed automatic transmission. However, should the road invite to a sportier driving style, the driver can select manual sequential shifting by using the gearlever on the central tunnel or by engaging Sport mode. The Sport GT Automatic version provides the driver with even more involvement in the gearchanging process via paddles located behind the steering wheel.
DuoSelect: Derived from Formula 1 technology, the DuoSelect six-speed manual transmission offers the ease of an automatic mode and the exhilaration of a clutchless racing gearchange. Around town, the automatic mode might be more convenient; but should the road invite a more spirited drive, a light touch on the two paddles behind the steering wheel is all that’s needed to shift up or down a gear. Pressing the Sport button then brings on the ultimate in dynamic driving, with even faster gearchanges, stiffer suspensions, a more powerful exhaust note and a lower level of intervention of the Maserati Stability Programme (MSP).
Transaxle and weight distribution
Every Maserati ever built has been renowned for its roadholding and handling qualities, and across these important criteria the Quattroporte delivers an amazing performance – thanks largely to its weight distribution, which maximises traction and thrust during acceleration so that the car remains exceptionally stable and well balanced at all times.
The Quattroporte DuoSelect features 47% front-53% rear weight distribution, unique in its segment. This comes courtesy of two highly specific technical solutions: the positioning of the engine further back in the chassis behind the front axle to shift the load back towards the cabin, and the adoption of the Transaxle layout which sees the gearbox rear-mounted in unit with the differential. The transaxle architecture is normally reserved for high performance sports cars and, in fact, this is the first time it has been applied to a luxury saloon.
In the Quattroporte Automatic, the engine is still located behind the front axle (its centre of gravity is 9mm further towards the rear of the car, compared to the DuoSelect version), thus transferring more weight to the centre of the car. The automatic gearbox, however, is mounted at the front; the car still features an extremely balanced weight distribution, with 49% of its weight at the front and 51% at the back, which enhances traction and acceleration, due to the additional load over the rear driving wheels.
Suspension – The Skyhook System
In the Maserati Quattroporte, the sensational roadholding and handling are matched by the very highest levels of ride quality and comfort. A highly sophisticated anti-dive and anti-squat suspension system, featuring front and rear double wishbones with arms and hubs in forged aluminium, enhances the car’s stability and safety by preventing the front end from diving under heavy braking, and the rear end from squatting down under fierce acceleration. In addition, the damping is automatically controlled by the acclaimed Skyhook system, which was developed in collaboration with racing engineers, Mannesmann-Sachs. Sensors constantly monitor vibrations and movements through the wheels as the car travels over different surfaces, and adjusts the settings of the dampers accordingly. The driver can then choose between two different settings: Normal for a more comfortable ride and Sport for a firmer, sportier drive.
The Maserati Quattroporte’s safety systems have been developed to match the outstanding performance of its 400 hp V8 engine. Four massive, ventilated disc brakes with aluminium, four-piston callipers combine with four-channel ABS and EBD to provide immense stopping capability.
– Brembo braking system with four self-ventilating discs (cross-drilled for the Sport GT); front 330 mm × 32 mm; rear 330 mm × 28 mm.
– fixed four-piston callipers with differentiated diameter at the front, four-piston callipers at the rear.
– anti-lock braking system ABS
– electronically controlled braking distributor EBD
– MSP stability control (includes ABS, EBD and ASR)
– Rigid steel body with aluminium bonnet and bootlid. In the event of a collision, the deformable structure is designed to absorb impact forces and turn the cabin into a highly resistant survival cell for the occupants. This conforms to the latest and most stringent safety standards for passenger protection.
– 6 airbags: 2 front, 2 side (front), 2 side curtain (front and rear).
– seat belts with electronically controlled pyrotechnical pretensioners.
– inertial switch (acting on the fuel pumps to prevent fire in case of a violent collision).
