The verdict

What's good

Nettuno engine was co-developed with Ferrari using F1-derived pre-chamber combustion
Long fastback roofline gives genuine rear headroom rare for a grand tourer
Folgore EV variant available on the same platform for buyers exploring electrification
Italian coachwork proportions remain among the most visually striking in the GT segment

What's not

Maserati's reliability record carries historical baggage that suppresses resale values
Infotainment system lags behind German grand tourers of the same era
Dealer network is thin in North America creating real service access concerns
Trunk space is noticeably compromised by the long sloping tailgate design

The engine

Nettuno

Twin-Turbo V6

A ferocious, high-revving V6 that pulls cleanly past 7,500 rpm with a hard, exotic edge, marking Maserati's return to building its own engines after years of Ferrari-sourced units.

Designed and built entirely by Maserati in Modena, near Maserati Corse's historic base, and named Nettuno (Neptune) after the trident-wielding god of the brand's logo.

Its Maserati Twin Combustion system borrows Formula 1 pre-chamber 'turbulent jet ignition' for road use, firing a small charge in a pre-chamber to ignite the main mixture.
It uses a dual spark-plug-per-cylinder layout: one in the pre-chamber, one in the combustion chamber.
Its roughly 210 hp per liter is an unusually high specific output for a road-car engine.
