When Maserati decided to retire its legendary twin-turbocharged V8 engine, it didn't just quietly phase it out of production. The Italian manufacturer engineered a definitive swan song that shattered performance benchmarks for four-door luxury cars. The Maserati Ghibli 334 Ultima arrived not merely as an appearance package, but as a calculated engineering push to claim a specific crown: the fastest internal-combustion production sedan in the world.
With a top speed of 334 kilometers per hour (208 miles per hour), this limited run of 103 units marks the absolute closing chapter for Maserati's iconic eight-cylinder architecture, which traces its modern lineage back decades. For enthusiasts tracking the intersection of Italian design and unadulterated displacement, understanding what makes this final iteration special requires looking past the marketing badges and examining the mechanical updates that set it apart from a standard Ghibli Trofeo.
Engineering the Final V8 Swan Song
The core of the Maserati Ghibli 334 Ultima is the familiar Ferrari-built 3.8-liter twin-turbocharged V8 (designated internally as the F154). In its final tune, this powerplant generates 572 horsepower (580 PS) and 538 lb-ft (730 Nm) of torque. While those output figures mirror the outgoing Ghibli Trofeo, straight-line speed required tackling aerodynamic drag and rolling resistance rather than simply adding raw power.
Reaching 334 km/h in a four-door sedan meant optimizing every millimeter of the car's profile. Engineers introduced a bespoke carbon fiber rear spoiler that cleans up high-speed airflow without upsetting the balanced silhouette of the body. Furthermore, Maserati fitted newly developed tires paired with lightweight 21-inch Orione alloy wheels. These changes reduced unsprung mass and lowered rolling resistance, allowing the sedan to punch through the air at velocities typically reserved for exotic two-seaters. To see the complete picture, we recommend the excellent report by The New York Times.
Power travels through an 8-speed ZF automatic transmission to the rear wheels, propelling the 4,300-pound saloon from zero to 60 mph in a blistering 3.7 seconds. It's a violent, theatrical acceleration curve accompanied by the deep, guttural exhaust note that enthusiasts have associated with Modena's eight-cylinder motors for generations.
Exterior Design and Interior Craftsmanship
A car bearing the Ultima moniker needs to announce its exclusivity without descending into pure tackiness. Maserati achieved this by offering the car in a signature exterior paint color known as Scià di Persia—a nuanced, pale blue hue accented by subtle carbon fiber exterior trim pieces on the bumpers and side skirts.
Inside, the cabin shifts away from cold, clinical carbon fiber toward tactile luxury. The seats are wrapped in a combination of premium leather and breathable Pale Terracotta Alcantara, accented by specific badging on the center console denoting the car's build number out of the 103 total units produced for global markets. Every touchpoint feels intentional, reminding the driver that this interior architecture will never be replicated in a modern Maserati sedan again.

Why the End of the V8 Matters
The retirement of the twin-turbo V8 marks a profound cultural shift inside the walls of the Modena factory. Strict emissions regulations and the industry-wide pivot toward electrification mean that high-displacement, forced-induction fuel burners are rapidly becoming collector items.
The Ghibli nameplate itself has phased out to make room for newer EV architectures and V6-powered GranTurismo platforms, making the Maserati Ghibli 334 Ultima a double-ended era. It closes the book on both the Ghibli sedan line and Maserati's standalone V8 era. Collectors recognize this duality, which explains why these final 103 units command intense interest on the secondary market compared to standard production variants from earlier model years.
Common Misconceptions About the Ultima
- It is not just a badge and paint job: While the engine output numbers match the Trofeo, the aerodynamic tuning, custom carbon fiber rear wing, and bespoke tire compound are unique to hitting the 334 km/h target.
- It is not a hybrid: Unlike newer sports sedans adopting heavy hybrid assist systems, the Ultima relies entirely on pure internal combustion, representing the final unfiltered mechanical expression of its lineage.
- Production was strictly limited: Maserati capped the run globally at 103 examples to honor the historic 1959 debut of the company's first V8 road car, the Maserati 5000 GT.
