Nettuno will be a twin-turbocharged 3.0-liter V-6 with double overhead camshafts. The engine is said to produce 621 horsepower at 7500 rpm, which is 500 revs short of the 8000-rpm redline and will be used in the new Maserati Corsa.

It is known that Maserati will finally release its all-new, sleek mid-engine Maserati Corsa 2020, referred to as MC20, in September. However, along with the teased photos of the latest Italian sports coupe, we now have some hard Intel about the engine that will power the MC20.

Nicely tucked between the coupe’s shapely hips, will be a twin-turbocharged 3.0-liter V-6 with double overhead camshafts. The engine has been named “Nettuno” which means Neptune in Italian. The cylinders are over-square with a bore and stroke of 88.0 millimeters and 82.0-millimeters respectively. The engine features an 11.0:1 compression ratio and has its cylinder banks placed at a 90-degree angle. Nettuno is lubricated by a dry-sump oil system that enables the 3.0-liters’ bellytrim to keep a low profile, of just 25.6 inches. The engine is said to produce 621 horsepower at 7500 rpm, which is 500 revs short of the 8000-rpm redline. The peak torque of 538 lb-ft occurs at 3000 rpm and stays constant all the way to 5500 rpm. While the power numbers are more than impressive for a small V-6, the thing that makes the Italian engine more interesting is the way it ignites its fuel.

The Nettuno utilizes two spark plugs per cylinder accompanied with a port and direct fuel injection. One of the spark plugs is conventional and off-center in the combustion chamber, while the latter is dead center, and is featured in a prechamber. When conditions are such that the pre-chamber is required to be used, a spark in the chamber ignites fuel and generates a star-shaped flame. This prechamber combustion is similar to the combustion process that is popularly used in Formula 1 engines, as it makes the operation more efficient.

The pre-chamber combustion, with the aid of advanced computer controls, also allows the setup to fluctuate between efficiency and maximum power. However, for the MC20,  the latter only intrigues us.

Maserati representatives have even assured that further information about the new engine will be released in due time.
