Aston Martin Racing boss David Richards says his team will resist switching to diesels in a bid to beat the dominant oil-burners from Peugeot and Audi at the Le Mans 24 Hours.
Aston’s LMP1 was the top petrol-powered car at the enduro classic last year - but it finished fourth, a full nine laps behind the winning Peugeot 908 HDi.
Le Mans’ rules are being modified over the next 12 months in a bid to create a more level playing field between diesels, petrols and hybrids.
But Richards told Autocar that Aston would remain focused on further developing its car’s DB9-derived V12 petrol powerplant.
“I cannot envisage Aston Martin building a diesel sports car,” he said. “We have been promised a more level playing field next year by the ACO [the race organiser] and we are seeking further assurances on that.
“Will we need to adopt hybrid technology in the future? We’d rather see a scenario where there is greater variety. If Aston Martin chooses to build a lighter car that is powered by petrol, then we’d like that to be accepted and reflected in the rules.”
