Maserati presents Nettuno: 100% new engine that adopts F1 technology for a road car

0

Maserati’s new era begins with a new engine. This new engine is the beating heart of the MC20 super sportscar that will make its world premiere in September. 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. Currently the new production line and new paint shop are being modified to host the much-anticipated MC20.

The new engine is the result of a technical revolution, one protected by international patents. The operation is a strategic one for Maserati, a brand that, today, is preparing to launch the new MC20, a project that is ‘100% Made in Modena’ starting right from it’s engine, the heart of the new car.

An ambitious design, which represents a historic moment for the company, a new era that will officially begin on September 9 and 10 in Modena during the event, “MMXX: The time to be audacious”. At the launch, new models will be revealed, which will go into production in the coming years, and innovative propulsion systems as well as ambitious programmes developed by the Casa del Tridente  will be announced.

The new power unit is a V90° architecture, with a 3-litre, 6-cylinder twin-turbo, and features a dry sump (a classic solution on super sportscars). It delivers 630 CV (620 bhp) at 7,500 rpm and 730 Nm of torque from 3,000 rpm with a specific power output of 210 CV/litre (207 bhp/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.

The engine has three main features: 

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

Lateral sparkplug: 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: linked to the fuel supply pressure at 350bar, the system reduces noise low down on the rev range, lowering emissions and improving consumption.
