There will be no Equivalence of Technology adjustments heading into next month’s FIA World Endurance Championship season-opening Four Hours of Silverstone, with LMP1 cars remaining at their initially declared performance levels from the Prologue.

Confirmed in a technical bulletin issued by the FIA on Thursday, both the Toyota TS050 Hybrid and non-hybrids from Rebellion and Ginetta will race at the same weight and power levels from the official pre-season test in Barcelona.

The maximum petrol per stint and maximum refueling rig restrictor diameters for the LMP1 non-hybrids, however, have been declared, with no change to last season with the exception of a slightly faster refueling times to match the Toyotas.

The normally aspirated Rebellion R13 Gibson will now have a 26.1 mm refueling rig restrictor, while the turbocharged powered AERs in the Ginetta G60-LT-P1s will be at 25.25 mm.

It compares to 24.75 mm (normally aspirated) and 24.2 mm (turbocharged) sized fuel rig restrictors used last year at Silverstone, with the Toyota’s unchanged at 20.40 mm.

ACO sporting director Vincent Beaumesnil told Sportscar365 that they intend to let the new Success Handicap system to “do the job” for LMP1 instead of evolving the EoT on a race-to-race basis this season.

The Success Handicap system will only go into effect beginning with the second round of the season at Fuji, taking into account the results from Silverstone.

Under the revised EoT for the 2019-20 season, Toyota will head into Silverstone 40 kg heavier than it did during last year’s race at the British circuit, with the ORECA-built Rebellion chassis 6 kg lighter year-to-year, along with a now unlimited max petrol energy allocation, which was rolled out during the 2018-19 season.

Fuel Capacities Confirmed for GTE Classes

No major changes have been made to the production-based categories since the Prologue either, with only fuel capacities having been recently confirmed.

The Porsche 911 RSR-19 will run with a 99-liter fuel capacity, while the Aston Martin Vantage GTE has been hit with a 2-liter reduction compared to the configuration it ran in Barcelona.

The GTE-Am class Aston, which is now running to the same generation as its GTE-Pro counterpart, has been impacted with the 2-liter reduction as well.
