LMP1 fuel flow levels for the opening three rounds of the FIA World Endurance Championship have been confirmed, following the latest set of bulletins issued by the FIA Endurance Commission this week.

The FIA has finalized the Equivalence of Technology (EoT) between gasoline and diesel-powered prototypes, based on data gathered by manufacturers in pre-season testing, including last month’s Prologue at Paul Ricard.

The revised table sees changes in the numbers that were originally published in December, with the gasoline-powered Porsches and Toyotas being given slightly more energy per lap, while also with a minor increase in fuel capacity.

The diesel-powered Audis, meanwhile, will face a marginal reduction in both energy and fuel capacity.

Both the Porsche 919 Hybrid and Toyota TS040 Hybrid will run in the 6 megajoules sub class, while Audi’s R18 e-tron quattro will be able to use a maximum of 2MJ per lap of Le Mans.

Teams will be limited to less hybrid power, based on the circuit length, for the opening two rounds of the season. No more than 4.02 MJ will be allowed for the Porsche and Toyotas at Silverstone, while the Audi can max out at 1.34 MJ per lap.

Additionally, the size of the refueling restrictors have been confirmed, with diesel-powered entries facing a slightly smaller opening compared to the gasoline LMP1 cars, which in turn, able to carry more fuel.

The published tables will remain unchanged for the opening three rounds, with a one-time adjustment period allowed following the 24 Hours of Le Mans that would lock in the specifications for a further 12 months.
