Press Ufficiale Maserati

"The Quattroporte is a high performance sports saloon featuring a light, sensual design that embodies all the most famous stylistic touches of Maserati in a contemporary language".

But the Maserati Quattroporte body design isn't just about looks; it has delivered a 12% improvement in drag (Cx), down to 0.31, and an enormous 24% reduction in lift. These figures reduce fuel consumption and increase high-speed stability.

A large part of the Quattroporte's aerodynamic work is out of sight, beneath the car. It has a flat floor that contains several aerodynamic features with the scope of optimising performance by lowering drag coefficient and keeping the proper cooling of all systems (engines, brakes, and transmission) at speeds over 300 km/h.

ENGINES

At the heart of the new Quattroporte is an entirely new engine grid, which follows recent Maserati tradition as it is designed in-house by Maserati Powertrain and manufactured under contract by Ferrari at Maranello.

V8 TWIN TURBO ENGINE AND PERFORMANCE

The flagship 3.8-litre V8 engine is a perfect representation of Maserati's performance tradition combined with a 20% reduction in emissions.

It is almost a litre smaller in capacity than the 4.7-litre V8 in the Quattroporte Sport GT S, yet this is more than countered through twin turbo charging and direct fuel injection to deliver 18% more power and 39% more torque.

The engine produces 390kW (530 hp) of power at 6800rpm and accompanies this with 650Nm of torque from 2000rpm to 4000rpm.

This maximum normal torque figure can be overboosted to 710 Nm from 2250rpm to 3500rpm.

These figures represent the highest specific power output in the class, with 139hp/l, and the best specific torque as well, with 171Nm per litre.

It also has a considerably more powerful engine than the finely balanced 4.7-litre engine in the Maserati Quattroporte Sport GT S, with a full 59kW (80hp) more power and an astonishing 200Nm more torque (on the overboosted output). The torque peak also arrives at less than half the engine speed of the Sport GT S's V8, too, peaking at 2000rpm versus 4750rpm.

In addition, its combination of a lighter body design and a stronger engine give the Quattroporte the best power-to-weight ratio in class, with just 3.6kg for each horsepower.

These engine figures help the Quattroporte reach 100km/h in just 4.7 seconds, which is 0.3 seconds faster than the previous Sport GT S, making the new Quattroporte the fastest accelerating four-door car in Maserati's history. This also makes it 0.6 seconds faster to 100km/h than the outgoing Maserati Quattroporte S and almost a second faster than the 4.2-litre Quattroporte.

Another ground-breaking figure is the Quattroporte's top speed, comfortably breaking through the 300km/h barrier to reach 307km/h (191 mph). Again, this makes it the fastest four-door Maserati in history and second amongst all Maserati production cars behind the mighty V12-powered MC12.

However, the new engine is not just about big performance numbers or high torque. Maserati engines have always been known for their incredible throttle response and that unique Maserati sound - and this engine is no different.

The new engine generation's smaller capacity does help with the Quattroporte's handling too, but Maserati's engineers concentrated mainly on delivering the brand's traditional crisp pickup and low rotational inertia.

The most technically advanced engine ever fitted to a Maserati, the 3799cc V8, uses a pair of low-inertia, twin-scroll parallel turbos to increase its output.

Its architecture retains the over-square, free-revving nature of the outgoing V8, with a bore of 86.5mm and a stroke length of 80.8mm, and it has a slightly lower compression ratio of 9.5:1.

It has been specifically designed to deliver exceptional performance at all engine speeds, combined with lower consumption and emissions. The engine diagrams show that the V8 engine's torque is very high, even at speeds as low as 1500 rpm.

It uses high-tumble cylinder heads with four cam phasers, (doubling the number of the naturally aspirated V8), in a concept refined by Maserati Powertrain for optimal combustion control to deliver high performance and low consumption.

With hydraulically adjusted roller finger followers and two continuous cam phasers for each cylinder head, it can advance or retard the inlet and exhaust valve timing independently in real time and it also reduces friction losses compared to old valvetrain systems.

Another characteristic feature of the new Maserati engine family is the 200 bar direct fuel-injection system. This very high pressure, coupled with seven holes laser drilled oriented holes injectors and multiple injection, helps atomising the fuel directly in the combustion chamber, thus improving the fuel-air mixture and the combustion process at any engine speed.

The new V8 engine is boosted by two small parallel twin-scroll turbines, (one for each bank of four cylinders), which provide the high performance expected of a Maserati engine while reducing inertia. Maserati Powertrain focused on integrating the turbine housing into the exhaust manifold for a compact, light-weight solution.

Each turbocharger is fed by its own air-to-air intercooler. The Quattroporte has two intercoolers, each mounted low and wide of the main radiators to catch a constant supply of fresh, cool air.

The engine also uses a state-of-the-art ECU, with integral high-speed processors, which handle an array of shifting functions in real time.

Maserati Powertrain has also switched to on-demand ancillaries, with a variable displacement oil pump that works under electrical control for improved consumption and performance.

It also uses an innovative, computer-controlled alternator, which monitors the vehicle's electricity consumption and manages the alternator's workload to suit.

The engine also operates in both Normal and Sport modes, along with Manual versions of either mode, operated by elongated shift paddles fixed to the steering column.

The new Quattroporte also introduces the I.C.E. (Increased Control and Efficiency) strategy, a function aimed at reducing consumption, emissions and noise.

It is a user-select strategy and delivers a softer throttle pedal response for smooth driving, cancels the turbocharger's overboost function and keeps the exhaust's Sport flaps closed until 5000rpm. It also adjusts the gearshifts to make them softer and slower and reduces torque at each gear's take-up point.

Besides delivering the Maserati Quattroporte's peak fuel efficiency figure, the I.C.E. mode is also very useful for driving on low-grip surfaces.

V6 TWIN TURBO ENGINE AND PERFORMANCE

The Quattroporte's all-new V6 twin turbo engine is a close relation of the V8, sharing most of its core components.

With 301kW (410hp) of power at 5500rpm, it still provides a tremendously powerful driving experience, especially with 550Nm of flat torque between 1500rpm and 5000rpm. In Normal mode the torque is smoothed at 500Nm in the lower rpm range, reaching the 550Nm threshold at 5000rpm to guarantee the 301KW of maximum power.

The engine shares the V8's bore and combustion chamber design, the same valves control technology (i.e. roller finger followers and four cam phasers), the same twin turbocharging approach and direct injection-ignition system. The engine auxiliaries are identical (alternator, starter motor and power steering pump) or very similar (variable displacement oil pump).

Nonetheless it has a character of its own, revving to a lower 6500rpm maximum speed and delivering its torque level of 500rpm sooner than the V8.

While its specific power output is slightly lower than that of the V8, at 137hp per litre, its specific torque is actually higher than the larger-engined car's standard specific torque, at 183Nm per litre.

It is also a lighter car, with 1860kg in its rear-wheel drive configuration (+70kg in all-wheel drive).

In rear-wheel drive mode, it accelerates to 100km/h in 5.1 seconds, while the all-wheel drive V6 twin turbo manages the sprint in 4.9 seconds.

Both cars are still as fast as people would expect from the Maserati brand, with the rear-wheel drive's 285km/h (177mph) top speed matching the outgoing Sport GT S and the all-wheel drive V6 twin turbo reaching 284km/h (176mph).

The rear and all-wheel drive models are also very similar in their fuel consumption, with both cars posting 10.5 l/100km on the combined cycle, with the rear-wheel drive car claiming 244 grams of CO2/km and the all-wheel drive 246 grams.

EXHAUST SYSTEM

In the best Maserati tradition, the sound and performance of the Quattroporte's exhaust system is controlled by pneumatic valves in the pipes of each bank in order to maintain the classic and rich sound characteristic of the brand.

In the default Normal mode, the bypass valves are closed up to 4,200 rpm to give a comfortable and discreet engine sound.

In Sport mode, not only does the car adjust a variety of handling parameters, but the exhaust valves are opened, giving the shortest possible high-energy route for the exhaust gases. This gives the Quattroporte its maximum engine performance and the unique Maserati engine sound.

Beneath the rear bumper, the V8 version finishes its exhaust system with trapezoidal tips with two double pipes in polished steel.

Andrò controcorrente ma a me proprio non piace, soprattutto il sedere...

addlightness · 6 Novembre 2012

dietro misto Audi-Peugeot

la nervatura che cambia convessità non mi piace, sporca la linea

sarebbe stata meglio una più corta, dritta, sfumata "d'avanti" () e dietro

Ubriacone · 6 Novembre 2012

Bella. Tanto bella. Elagante e sportiva. Gran macchina, complimenti!

AlexMi · 6 Novembre 2012

A me piace moltissimo, anche e soprattutto dietro.

Quello che non mi piace sono le dimensioni, assurdamente enorme, ma ovviamente vale anche per le concorrenti di quel segmento.

actarus8v · 6 Novembre 2012

troppo grande IMHO......la linea laterale è molto bella, davanti e dietro ci sono alcuni particolari (i fari) che non mi piacciono /emoticons/wink@2x.png 2x" width="20" height="20" />

andrebbe vista dal vivo.......design degli interni non eccezionale, in particolare la zona tunnel/plancia

Ciumaca · 6 Novembre 2012

nn mi sembra un gran che, mi convince poco... beh pazienza cmq nn posso permettermela /emoticons/happy@2x.png 2x" width="20" height="20" />

beckervdo · 6 Novembre 2012

Voci di corridoio siamo sui 5.25 metri

E' una limousine.

Ed è prevista anche la versione a passo Lungo per rompere le palle ad Continental e Ghost

LUPINN · 6 Novembre 2012

Non vedo perchè darle contro per le dimensioni..

se dev'essere una vera ammiraglia e soprattutto un SALOTTO, dev'essere così!

beckervdo · 6 Novembre 2012

Messo anche il sondaggio /emoticons/biggrin@2x.png 2x" width="20" height="20" />

LUPINN · 6 Novembre 2012

Votato

AleArturo · 6 Novembre 2012

E' bella.

E che sia 5.25m non è un problema, nasce per essere un'ammiraglia opulenta.

Il problema è che, credo, nel 2003 la Quattroporte 5a serie fosse più bella. Ha resistito meravigliosamente alle insidie del tempo per quasi 10 anni e non so se questa riuscirà a fare altrettanto.

La precedente era più compatta, ed era una ammiraglia anch'essa.

Il marchio Maserati dovrebbe mettere al primo posto il dinamismo anche sulle ammiraglie.

Diciamo che avevano il mercato americano come target, per quello europeo aspettiamo la Ghibli, che dovrebbe essere favolosa e grande il giusto.

elkine · 6 Novembre 2012

Bah...

ma le frecce arancioni non andavano di moda qualche anno fa? O è la versione usa?
