American Le Mans Series GT1 champion team Corvette Racing will switch their C6.R cars to a 'greener' ethanol fuel this season.
The factory-backed Chevrolet squad had little competition in the class last year after Aston Martin decided not to enter, and marque general manager Ed Peper believes the team's dominance will continue with the E85 (85 per cent ethanol) fuel.
He said:"By showcasing the capability of ethanol to an audience of knowledgeable race fans, we can demonstrate the benefits of renewable fuel in racing."
Chevrolet's decision to run the greener fuel comes on the back of the ALMS announcing partnerships with three environmental bodies in America, which it will use to encourage more teams and manufacturers to make the switch to bio-fuel.
Drayson Barwell Aston Martin will also run a greener fuel in ALMS this year, with Jonthan Cocker and Paul Drayson due to share a bio-fuelled GT2 Vantage from the third round at Long Beach.
