Overview
- Maserati revealed the Project GT4 prototype at the Goodwood Festival of Speed on Thursday as the start of a multi-year development aimed at fielding a GT4‑compliant GranTurismo racer in the 2028 season.
- The prototype uses a 3.0‑litre Nettuno V6 with Formula‑1 derived pre‑chamber combustion that can produce very high peak outputs in prototype form but will be detuned to meet GT4 rules and Balance of Performance.
- Maserati says the racer trims roughly 400 kg from the road car and gains race hardware such as a splitter, dive planes, a large rear wing, dedicated brakes with cooling, a roll cage, and 18‑inch GT4 wheels.
- Andrea Bertolini has been named lead test driver and Maserati Corse will run the programme from Modena with the stated goal of delivering a competitive, reliable and customer‑accessible car for teams.
- The project ties into Maserati’s centenary livery and its recent motorsport push, building on the marque’s early 2000s GT4 pedigree with the Trofeo Light and later GranTurismo GT4 models while homologation and race detune targets are still to be achieved.
