There are a few Formula 1 derived technology made it into the new Maserati engine such as the innovative pre-chamber combustion system featuring twin-spark plugs. There are 3 main feature that makes this powerful.

The three main features of the engine are: 

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.

The new “Made in Modena” engine, a traditional 90° V6, has been taken to unheard of power and torque levels and will be used for the first time on the MC20 super sportscar. The MC20 will take Maserati back to the world of racing.
