Maserati has presented its Project GT4 at the 2026 Goodwood Festival of Speed, previewing a GranTurismo-based customer racing car scheduled to enter competition in 2028.
Developed by Maserati Corse in Modena, the Project GT4 draws on experience gained with the Maserati GT2 and will extend the company’s current racing programme into the more widely contested GT4 category. Maserati says development has begun, although the car’s final homologated specification, price and delivery schedule have not yet been announced.
The Project GT4 retains the road-going GranTurismo’s aluminium architecture, body structure and 3.0-litre twin-turbocharged Nettuno V6. The engine is mounted longitudinally at the front and uses Maserati’s pre-chamber combustion system, although its intended GT4 power output has not been confirmed. Maserati says versions of the Nettuno engine have produced more than 700bhp in other applications. Its eventual output will be governed by the category’s homologation process and Balance of Performance regulations.
Drive is sent to the rear wheels, in contrast to the road car’s four-wheel-drive setup, while the suspension is derived from that of the GranTurismo Trofeo. Adjustable dampers and anti-roll bars allow the chassis to be configured for different circuits and conditions. The removal of road equipment and the use of competition components are expected to reduce weight by approximately 400kg compared with the production GranTurismo. Maserati says retaining the road car’s principal architecture and powertrain should also help control maintenance and operating costs for customer teams.
Its aerodynamic package includes a front splitter, dive planes, vented bonnet and additional components intended to increase downforce. The front end has been revised to incorporate the racing hardware while, while other competition equipment includes a roll cage, homologated racing seat and fuel tank, a dedicated braking system with additional cooling and 18-inch wheels built to GT4 regulations. The cabin retains elements of the production car’s dashboard design, but has been reorganised around the controls and information required by the driver on track.
Maserati chief test driver Andrea Bertolini is involved in the development programme. Bertolini previously raced the Maserati MC12 and won four FIA GT drivers’ titles between 2006 and 2010, as well as the FIA GT1 World Championship in 2010. “Our objective is clear: to develop a car that is competitive, reliable and accessible to the teams and drivers who choose Maserati,” said Maserati Corse head Vincent Biard. “The development process has just begun, but we are already working to reach the 2028 season with a car that can compete at the highest level.”
The prototype shown at Goodwood carries a livery marking the centenary of Maserati’s Trident emblem. A large Trident extends from the roof towards the rear, accompanied by 100 smaller tone-on-tone blue emblems. Its white front section refers to historic Maserati racing cars including the 420M/58 Eldorado, while the blue and yellow sections use the colours of Modena.
The Project GT4 will sit alongside the Maserati GT2, introduced for customer competition in 2023, and the track-only MCXtrema. Maserati returned to international GT racing with the GT2 after previously competing in the category with the MC12. Maserati has also produced GT4 machinery before. The GranSport-based Trofeo Light competed in the GT4 European Cup, while a previous GranTurismo GT4 appeared in the GT4 European Series and related championships.
Further testing and development of the GranTurismo-based Project GT4 will take place before its planned competition debut during the 2028 season. More details can be found here.
