Maserati Reveals Details on First Post-Ferrari Engine: the Nettuno


Maserati has just unveiled their first post-Ferrari engine: the Nettuno. The beating heart of its upcoming MC20 super sportscar, the Nettuno is the Italian carmaker’s first completely in-house developed engine in 20 years.

The Nettuno engine is a dry sump 3.0-liter V6 twin-turbo outputting 630 horsepower and 730 Nm of torque. Its compression ratio is 11:1, while the stroke is 82 mm and the bore, 88 mm.

The engine features Formula 1 derived technology which is made available on a road car for the very first time. The Nettuno 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.
After its application in the MC20 super sportscar, Maserati’s “Made in Modena” engine will take them back to the world of motorsports as well.
