Maserati's clever 621hp Nettuno V6 will only ever make it into one car

Suddenly, the MC20 looks even more special

The new Maserati MC20 marks a new chapter and direction for the Italian marque, and goes far beyond being their only true 'supercar' as it is the genesis of a new range of vehicles, designed to turn around the brand and bring it back to its full glory.

Like many brands, Maserati are embracing electrification, but the hand-built V6 in the MC20 makes use of top-shelf F1 technology, in order to avoid electrification to meet emissions guidelines - clever stuff.

However, the engine will only ever be used in the MC20. Speaking to Autocar Magazine, Matteo Valentini - Chief engineer for high-performance engines for Maserati, said "the Nettuno is built only for the MC20, so you will see it only on that car." However, he did say that technology used in developing the Nettuno engine would be used on other future projects, so this may not be the last un-electrified car we see from Maserati.

Named after the Roman god Neptune, the Nettuno engine produces 621hp and 583 lb/ft of torque, and makes its impressive power output thanks to its unique pre-chamber technology. In essence, this is an extra air-fuel mixture chamber with a second spark plug in the engine above the combustion chamber, igniting the air-fuel mixture at multiple points, rather than the single point in the combustion chamber.

The result of this technology, the first of its kind in a road car, is increased power and reduced turbo lag, since they managed to avoid using larger turbos to develop higher power output.

The other bonus of this technology is that Maserati can now use this tech on a further line of non-electrified future vehicles, so we look forward to seeing just what Maserati do with this fascinating technology, and whether it will be used by any other supercar manufacturers in the future.

  • I was wrong about this car. I think it'll age tremendously well.

  • Mmm I thought the new SUV from them was supposed to get it too? Not in the same tune I’m sure but, there’s a couple leaked images of a vehicle based on the Alfa Stelvio... maybe stay tuned for that 😏. Hagerty did an article on it I think is where I saw that.
