Maserati has revealed details of its new Nettuno V6 engine which is set to debut in September powering the incoming MC20 supercar.

 

The new engine is a 3.0-litre six-cylinder twin-turbo with a dry sump. It offers 463kW at 7500rpm and 730Nm of torque from 3000rpm, with a specific power output of 210CV/litre. The compression ratio is 11:1, the stroke is 82mm and the bore 88mm.

 

For context, the Nettuno will be FCA’s most powerful V6 eclipsing the 397kW produced by the 2.9-litre biturbo unit used in the Alfa Romeo Giulia GTAm. It also beats the 338kW/520Nm 4.7-litre naturally-aspirated V8 that powered Maserati’s outgoing GranTurismo.

 

Technology from Formula 1 is brought to the road via three main features of the engine. This includes a pre-chamber which is a combustion chamber set between the central electrode and the traditional combustion chamber and connected by a series of specially-designed holes.

 

There is also a lateral sparkplug which acts as a support to ensure constant combustion when the engine is operating at a level that doesn’t need the pre-chamber to kick in.

 

Additionally, there is a twin injection system utilising direct and indirect injection. This reduces noise low down on the rev range, lowering emissions and improving consumption.

 

The unit was designed at Maserati’s Modena facilities: the Maserati Innovation Lab on Via Emilia Ovest, the workshops on Via Delle Nazioni (Maserati Corse’s historic base) and developed at the Engine Hub, situated at the famous Viale Ciro Menotti address where it will be built as part of Maserati’s ‘100% Made in Modena’ project.

 

A new production line and paint shop are currently being modified at Modena to accommodate the production of the MC20 which will be revealed in September.
