The Britcar Endurance Championship has unveiled it’s proposed new class structure for the 2027 season. Over the 10 years since the Championship was revitalised under the current management, Britcar has proactively developed it’s categories to reflect the changing appetites in endurance racing, and new for 2027 are discrete classes for the Porsche Cayman and Ginetta G55, so there will be five classes for the coming season, based around power-to-weight ratio and specific car homologation.
Challenge (351 – 475 bhp/tonne)
Lamborghini Super Trofeo, Porsche 991 and 992 Cup, Ferrari 458 and 488 Challenge, balanced using different-length pitstops. Also included are cars not built to the above specification but not exceeding 475 bhp/tonne.
GT (311- 350 bhp/tonne)
Cars originally built to GT4 regulations, plus cars not built to the above specifications but not exceeding 350 bhp/tonne, including Ginetta GTP8, BMW E46, McLaren 570s Trophy, etc.
Cayman – New class for 2027
The regulations will follow a simplified and sanitised version of the original Porsche Sprint Challenge technical regulations to minimise costs, while performance will be regulated to ensure a level playing field.
Ginetta – New class for 2027
Ginetta G55 cars running to the published technical regulations. Varying specifications of G55 wil be balanced using weight, bhp and pitstop lengths to ensure close and competitive endurance racing.
Trophy (Up to 310 bhp/tonne)
Cars meeting a maximum power-to-weight ratio of 310 bhp/tonne, plus Ginetta GTA cars running to the published technical regulations
All cars will be checked for power using onboard dataloggers to ensure compliance with the regulations. BHP measured at the flywheel. Goodyear Racing slick or wet tyres are mandatory.
