Maserati has used the Goodwood Festival of Speed 2026 to show where its modern GT racing ambitions are heading.
The new Project GT4 takes the GranTurismo as its starting point, then strips it back, sharpens the hardware and gives the Nettuno V6 a competition-focused edge.
It’s not simply a road car with numbers on the doors, either. Maserati is positioning it as a future GT4 racer, with competition plans set for 2028.
At a glance
- Maserati has unveiled the GranTurismo-derived Project GT4 at the Goodwood Festival of Speed 2026.
- Its 3.0-litre Nettuno V6 produces more than 700 hp and uses Formula 1-derived pre-chamber combustion.
- The car is being developed for GT4 racing from 2028, with rear-wheel drive, adjustable dampers and 18-inch wheels.
A GranTurismo with a harder racing brief
The Project GT4 keeps the GranTurismo connection visible, but the brief is far more focused than grand touring.
Maserati has removed around 400 kg compared with the road-going GranTurismo, a major change for a car intended to spend its life chasing lap time rather than motorway comfort.
That weight reduction should reshape the character of the platform, giving the Project GT4 the lighter, more direct feel expected of a customer racing machine.
The visual treatment makes the point quickly, with a dedicated livery and a large Trident graphic placed prominently across the hood.
Nettuno V6 power with Formula 1 combustion thinking
At the centre of the Project GT4 is Maserati’s 3.0-litre Nettuno V6, here pushed beyond 700 hp.
The headline output is only part of the story, because the engine also uses Formula 1-derived pre-chamber combustion technology.
That system is designed to improve combustion efficiency and support cleaner, stronger power delivery, both of which matter when an engine is being developed for the demands of circuit racing.
Power goes to the rear wheels, keeping the car aligned with the traditional layout expected from a serious GT racer.
Chassis hardware aimed at circuit setup work
The Project GT4 uses a race-focused suspension package evolved from the Trofeo, with adjustable dampers that allow setup changes for different tracks.
That adjustability is crucial in GT4 racing, where a car needs to work across circuits with very different surfaces, kerbs and braking zones.
The car also rides on 18-inch wheels, in keeping with its GT4 positioning.
Maserati hasn’t presented the Project GT4 as a styling exercise. The specification points to a machine being shaped around regulation racing, not just demonstration laps.

The Project GT4 arrives as a clear statement that Maserati wants the GranTurismo’s performance story to extend well beyond the road.
If the finished race car retains this mix of reduced weight, serious power and competition-ready chassis tuning, it could give the Trident a compelling presence on future GT4 grids.
