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. 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.
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.
