Maserati is in the midst of a redo. The brand is reshaping its image, starting with its allegiance to its home country of Italy. For months, the automaker, a division of FCA, has been pushing has on the message that its future is fully Italian, despite the looming merger between its American-Italian owner and the French PSA Groupe.

The next step in its product plans was to shift development and production of its engines to Italy. The Maserati Nettuno is the result of a team of Maserati technicians and engineers working at the Maserati Innovation Lab on Via Emilia Ovest and the workshops on Via Delle Nazioni to design the engine. It was developed at the Engine Hub, located at the Viale Ciro Menotti address where it will be built.

Maserati's new engine is a twin-turbocharged 3.0-liter six-cylinder unit with V90-degree architecture. It's capable of delivering 621 horsepower at 7500 rpm and 538 pound-feet of torque from 3000 rpm.

The engine features a dry sump pump and has an 11:1 compression ratio. The stroke is 82 mm and the bore 88 mm.

The Italian automaker says the that "soul of the engine" its its pre-chamber combustion system that features twin-spark plugs. The chamber is set between the central electrode and traditional combustion chamber and connected by a series of specially-designed holes. The lateral spark plug is traditional in its action.

This technology is derived from Formula One use and will make its debut in a passenger car this autumn.

The twin-injection system is linked to the fuel supply pressure at 350 bar, working to reduce noise in the low rev range, which lowers emissions.

Maserati has lowered the traditional development time of an engine by utilizing virtual analysis via the Innovation Lab.

The engine will be employed first in the Maserati MC20, which is set to bring Maserati back to the world of racing. It is expected to debut in September.
