MC20 super sportscar to be first Maserati to adopt new engine later this year

Maserati unveils new ‘Nettuno’ engine

Maserati has revealed the technical specifications of its new Nettuno engine, a three-litre, six-cylinder, twin-turbo powertrain featuring a dry sump and taking the form of a traditional 90° V6.

The unit was designed at Maserati’s Modena facilities and developed at the ‘engine hub’, situated at the famous Viale Ciro Menotti address where it will be built.

Currently the new production line and new paint shop are being modified to host the much-anticipated MC20.

After twenty years, Maserati has once again enthusiastically taken on the challenge of returning to its Modena HQ with the development and production of a new, highly-technological, high-performance engine.

The operation is a strategic one for Maserati, a brand that, today, is preparing to launch the new MC20, a project that is ‘100 per cent Made in Modena’.

Nettuno engine specifications

The new power unit is a V90° architecture, with a three-litre, six-cylinder twin-turbo, and features a dry sump – a classic solution on super sportscars.

It delivers 630CV at 7500rpm and 730 Nm of torque from 3000rpm with a specific power output of 210CV/litre.

The compression ratio is 11:1, the stroke is 82 mm and the bore 88 mm.

The soul of the engine is the innovative pre-chamber combustion system featuring twin-spark plugs.

This technology is derived from Formula 1 and is now available, for the first time, on an engine destined for the road.

A ‘pre-chamber’ combustion chamber is set between the central electrode and the traditional combustion chamber and connected by a series of specially-designed holes.

A traditional sparkplug 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.

Twin injection system, direct and indirect, is linked to the fuel supply pressure at 350bar.

The system reduces noise low down on the rev range, lowering emissions and improving consumption.
