Maserati Quattroporte: Executive GT And Sport GT

Maserati Quattroporte

Maserati Quattroporte

Perfect balance of elegance and sportiness

The Maserati Quattroporte effortlessly combines the two different souls of a luxury saloon and a thoroughbred sports car. A stunning mix of avant-garde technical solutions guaranteeing performance, road-holding and safety, Pininfarina design and a sophisticated cabin make it an authentic Italian flagship car.

The engine - 400 hp V8

The Quattroporte’s 4,244cc 90° V8 engine is light and compact, weighing in at just 183 kg. Its architecture is worthy of the most advanced racing engines, punching out a specific power of 95.2 hp/litre. Chain-driven twin overhead camshafts per cylinder bank command four valves per cylinder with hydraulic tappets. The intake cams feature continuously variable phase timing, and also have a new profile expressly designed for the Quattroporte engine, which optimises its responsiveness. There is also an electronic drive-by-wire accelerator.

The Quattroporte’s V8 engine has a specific and fluid power delivery curve for top class ride comfort and smooth driving: the revs increase gradually and smoothly and the engine delivers a massive 400 hp (295 kW) at 7,000 rpm. Over 75% of the maximum torque (360 Nm out of a maximum 451 Nm at 4,500 rpm) is available at just 2,500 rpm. Combined with the MDS (Maserati DuoSelect) transmission, it offers maximum pleasure in day-to-day driving as well as in more press-on situations. The Quattroporte offers performance parameters that simply cannot be beaten in the luxury saloon segment: it comfortably delivers a 171 mph top speed and sprints from 0 to 62 mph in just 5.2 seconds.

MDS transmission - one gearbox, two souls

The six-speed electro-hydraulic Maserati DuoSelect (MDS) transmission system is one of the Quattroporte’s finest innovative features. On ignition, the system selects the automatic driving mode which offers smooth, rapid gear changing combined with top class responsiveness. This means that the driver can relax and appreciate the comfort of the car without having to worry about manually shifting the gears. There are none of the usual disadvantages associated with a normal torque converter either: the engine is wonderfully responsive and starts every time from cold with incredibly smooth upward gear changing.

The MDS gearbox also offers a much sportier kind of drive. Using the paddles mounted on the steering column, the driver can override the automatic mode without actually deactivating it. If he wants to disable it, however, all he has to do is push a button on the central console. This gives the kind of responsiveness required by a sportier driving style. There is no clutch pedal, of course, and the hill holder function makes hill-starts very easy too.
