4.7 litre ENGINE
The dual soul as luxury saloon with sports-car performance of the new Quattroporte range finds its ultimate expression on board the Quattroporte S, equipped with the outstanding 4.7 litre V8 delivering a maximum power output of 317 kW (430 CV) at 7,000 rpm, and a maximum torque of 490 Nm at 4,750 rpm.
Easily identifiable thanks to its red cylinder head covers, it is the top of the range of a new family of wet sump engines developed by Maserati engineers to ensure smooth ride and unbeatable performance.
The technical features incorporated in this unit, with speeds rising to 7,200 rpm, have further upgraded the impressive qualities of the latest Maserati engines, i.e. the high specific power output and the capacity for rapid rise and fall in rpm, for an even more thrilling driving experience.
Fully responsive in all driving conditions, the 4.7 litre V8 reveals astonishing acceleration even in high gears, particularly useful during motorway journeys. This plus-factor is achieved through the skilful harmonisation of the shapes of the intake and exhaust ducts, combined with the use of continuous-actuation timing advance processors on the intake camshafts, optimisation of the combustion chamber and the way the engine itself is calibrated to deliver 82% of torque at just 2,500 rpm.
Exhaust/evap emissions and fuel consumption fully comply with the planned Euro 5 regulations for European and LEV2 for the US, thanks to the introduction of an innovative perforated metal sheet catalytic converter that combines permeability and reliability.
The new engine performance figures represent the pinnacle of the Quattroporte range:
- Maximum power output: 317 kW (430 CV) at 7,000 rpm
- Maximum torque: 490 Nm (358 lbft) at 4,750 rpm
- Top speed: 280 km/h (174 mph)
- Acceleration 0-100 km/h (0-62 mph): 5.4 s
THE AUTOMATIC TRANSMISSION
Quick changes for immediate response, fluid and progressive, for the greatest driving comfort.
The automatic transmission of the Quattroporte, featuring a hydraulic torque converter, is the result of a state-of-the-art collaboration between Maserati and ZF which enhances the V8’s progressive delivery at low-medium revs without limiting its power, allowing changes at engine speeds up to 7,200 rpm.
Besides the Normal driving mode, there are two additional automatic gear change modes, ICE and Sport, so the driver can choose the most suitable one according to the road conditions and his/her personal driving style.
Like the true sports saloon that it is, the Quattroporte can also be driven manually using the gear lever on the central tunnel, or the optional gearshift paddles behind the steering wheel. The sixth gear has been optimised to reduce fuel consumption and noise even further during motorway use at high speeds.
In the Quattroporte S, the new, more aggressive power delivery of the 4.7 litre engine is combined with a specific gearbox software, developed to optimise the acceleration and the sporty feel of the automatic transmission.
WEIGHT DISTRIBUTION
Safe and easy to handle on any road condition, the secret behind the balanced behaviour of the Quattroporte lies in its weight distribution, a real one-of-a-kind in this segment, with slightly more weight on the rear axle (49% on the front and 51% on the rear). This configuration, obtained by placing the engine behind the front axle, maximises traction and acceleration.
THE BRAKING SYSTEM
DUAL-CAST BRAKES FOR THE NEW QUATTROPORTE S
The new Maserati Quattroporte S is equipped with a high performance braking system featuring dual-cast front discs, developed together with Brembo, first used with excellent results on the Quattroporte Sport GT S. Thanks to the co-fusion of materials, this technology conjugates the benefits coming from the high-temperature performance of cast iron to the light weight of aluminium.
Monobloc aluminium brake callipers with six pistons of different diameters (30/34/36 mm) are used for the front dual-cast discs, as they are more resistant to deformation than ordinary two-piece callipers. The greater efficiency at any working pressure leads to a shorter brake pedal stroke.
NEW LIGHTING SOLUTIONS
NEW LED LIGHTS
The technical evolution of the new Quattroporte is obvious at a glance thanks to the lighting system, redesigned to optimise every individual function. The LED technology adopted on both the front and rear lights represents a visually strong impact innovation for the new Quattroporte, and is one of the main elements of continuity with the Maserati GranTurismo stylistic elements.
The evolution in the lighting system is not limited to LEDs. The main component of the front headlights is a bi-xenon lamp providing full-beam and dipped functions, complete with the new Adaptive Light Control system.
For the first time the new Quattroporte is equipped with a Daytime Running Light function, which uses the side lights.
