Maserati has built a reputation for its bold identity. This trait has always been accentuated by the potent turbocharged engines sourced from Ferrari—a 3.0-liter V6 and a 3.8-liter V8. However, with the impending conclusion of their contract with Ferrari, Maserati is embarking on a new path. The company has decided not to extend the partnership, as it focuses on not only its electrification strategies but also on developing two in-house engines for its future vehicle lineup, as per information from Automotive News Europe.
The new engines are a 3.0-liter V6 and a 2.0-liter inline-four, designed to enhance efficiency and reduce emissions. Additionally, these engines signify the end of the era of V8 powerplants in Maserati vehicles. The next-generation GranCabrio, GranTurismo, a mysterious mid-size SUV, and the anticipated mid-engine supercar, MC20, will all be equipped with the 3.0-liter twin-turbo V6. The V6 will generate between 523 to 542 horsepower in the sports cars and SUV models, whereas the power output for the MC20 is yet to be disclosed.
Maserati also plans to introduce an electrified variant of the V6 with even more power, although the specifics of this electrification remain undisclosed. This could involve a mild-hybrid setup similar to what Mercedes employs on its 3.0-liter inline-six, possibly incorporating an electric supercharger, or a plug-in hybrid system where electric motors power one of the axles, akin to Volvo’s hybridized T8 models.
An interesting fact about this V6 engine is the F1-inspired technology incorporated. Departing from a conventional cylinder head layout, the new engine features a pre-ignition chamber for utilizing Turbulent Jet Ignition. This innovation aims to match, or even surpass, the 572 horsepower output of the current Ferrari-supplied 3.8-liter V8.
For the curious minds, Turbulent Jet Ignition essentially is a compact combustion chamber atop the cylinder equipped with its fuel injector and spark plug. This chamber, mostly isolated from the rest of the cylinder, has tiny apertures for injecting hot fuel-air jets, creating turbulence that aids in better filling the cylinder space. This approach allows for leaner mixtures with higher compression ratios, promoting a cleaner and more efficient combustion cycle.
This technology marks its debut in a mass-produced street car. Notably, this technology contributes significantly to the efficiency achievements of Mercedes’ Formula 1 powertrains, reaching an impressive 50% efficiency, a rarity in the realm of internal combustion engines.
The introduction of a four-cylinder engine brings a less thrilling narrative. This engine, a 2.0-liter powerplant seen in models such as the Jeep Cherokee and Wrangler, has been slightly modified by Maserati. Alfa Romeo also leverages this engine, known as the GME, as the base offering in the Stelvio SUV and Giulia sedan, delivering up to 275 horsepower in the Stelvio’s top trim.
The four-cylinder engine is slated for initial use in the Ghibli, accompanied by a 48-volt hybrid mechanism for added power and efficiency. This hybridized four-cylinder Ghibli is scheduled for a grand unveiling on July 15th.
Maserati’s success hinges on the reception of these new engines and upcoming models. While the brand previously experienced a surge in revenue with the economical Ghibli, its sales took a hit during the pandemic, plummeting by 46% in the initial quarter of 2020. Thus, bidding farewell to Maserati’s V8 legacy stands as a necessary financial measure that, though not musically desirable, aims to secure the brand’s future prosperity.
