Toyota Gazoo Racing will race at Silverstone with a further weight increase from the Equivalence of Technology values applied at last month’s Prologue test at Circuit de Catalunya as the FIA and ACO work to establish the baseline for the coming season’s EoT and LMP1 success ballast systems.

A further 14kg has been added to both Toyota TS050s ahead of Sunday’s four hour Silverstone opening round of the 2019/20 FIA World Endurance Championship.

That sees the minimum weight of the Toyota TS050 Hybrid sit at 932kg for Silverstone, 14 kilos up from Barcelona, which was itself 14 kilos up from the final round of last season.

The latest change sees the TS050s running at 108 kg heavier than the pair of Rebellion Racing R13 Gibsons, and 99kg heavier than the Team LNT Ginetta G60-LT-P1s, the non-turbo and turbo-powered non-hybrids still featuring different EoT values.

The weight change is in addition to the further major shift, away from both fuel stint and pitstop advantages for the Toyotas. A statement from the FIA and ACO also today explained the further weight change:

“In light of data gathered in July in Barcelona, particularly regarding the hybrid cars, we decided to rework the EoT to ensure that we are leaning towards this broader target.”

“We also introduced an LMP1 success ballast which is based on championship points and has been designed to create a thrilling championship, race after race. However, to implement work, we need a good EoT baseline.

“After careful examination, we decided that an adjustment of the baseline established for Barcelona was needed.”
