Maserati’s new 621bhp twin-turbocharged V6 – the primary engine it has produced in-house for greater than 20 years – can be provided solely within the MC20 supercar, however know-how from it should seem elsewhere.
Named in reference to the Roman god who impressed the Italian agency’s trident brand, the Nettuno is being developed and hand-built on the new Maserati Engine Lab in Modena.
Producing 583lb ft of torque together with 621bhp of energy, the three.0-litre engine is solely freed from electrification, as an alternative utilizing a twin-combustion ignition system to enhance response.
Derived from Method 1 know-how, every of the 90deg-mounted cylinders options an additional pre-chamber containing a second spark plug, together with a dual-direct-injection system. Gas could be fed into each chambers, with the dual sparkplugs permitting every to be fired individually. Maserati says this improves the engine’s response whereas additionally decreasing gasoline comsumption and decreasing emissions.
The Nettuno has been developed for the MC20 – which may even be provided in future with an electrical powertrain – however Matteo Valentini, Maserati’s chief engineer for high-performance petrol engines, stated that it will not be constructed elsewhere.
“The Nettuno is constructed just for the MC20, so you will notice it solely on that automotive,” he stated. “However the plan is that the know-how from it, notably the twin-combustion system, can be used on many different engines sooner or later.”
Maserati is presently growing a brand new vary of automobiles, together with the Grecale small SUV and new variations of the Granturismo and Grancabrio, which can be provided with a variety of petrol and electrified engines. It is seemingly that the twin-combustion know-how can be provided on higher-end efficiency variations of these fashions.
Maserati did not specify whether or not powertrains that includes its know-how will solely be provided on solely its fashions or is also utilized by different Stellantis manufacturers.
Whereas pre-chamber know-how has been utilized in engined beforehand, Maserati claims the Nettuno is the primary manufacturing highway engine to function it and has patented key components of its know-how.
Numerous rival supercar corporations have turned to electrified hybrid know-how to extend energy and cut back turbo lag, however Valentini stated the pre-chamber know-how enabled Maserati to retain a pure-petrol unit.
“After we set the efficiency parameters of the engine, our first selection was to extend the scale of the turbocharger and introduce some e-booster to eliminate the lag,” he stated. “After we analysed it, we determined that was costly, not very dependable and really difficult.
“With the pre-chamber know-how, we may generate the efficiency and effectivity we needed however hold the identical dimension of standard turbocharger.”
