Maserati engine adopts F1 technology
The new engine for Maserati’s MC20 sportscar 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. The new production line and new paint shop are being modified to host the much-anticipated MC20.
The new power unit is a V90° architecture, with a 3-litre, 6-cylinder twin-turbo, and features a dry sump. It delivers 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.
The engine features an innovative pre-chamber combustion system with 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.
