Toyota Gazoo Racing said Silverstone’s new curbs caused enough damage to its two TS050 HYBRIDs to cause both cars to fail post-race technical inspection, and with it, exclusion from the 6 Hours of Silverstone results.
“TOYOTA Gazoo Racing has lost its one-two victory in the 6 Hours of Silverstone following a post-race technical inspection,” Toyota Gazoo Racing said in a statement.
“The No.8 TS050 HYBRID of Sébastien Buemi, Kazuki Nakajima and Fernando Alonso crossed the line to win the third round of the FIA World Endurance Championship from Mike Conway, Kamui Kobayashi and Jose Maria Lopez in the second-placed No.7 TS050 HYBRID.
“Both cars suffered damage to their respective front floor areas during the race due to impacts against the new curbs at Silverstone. Regrettably, this also caused both cars to fail deflection tests in post-race scrutineering. As a result, race stewards disqualified both cars.
“The design and construction of the part concerned has not changed since its introduction at the beginning of the 2017 season. Since then it has successfully passed similar tests, most recently at Spa this season.
“The team is now evaluating its next course of action.”
If the team decides not to appeal, Rebellion Racing’s Gustavo Menezes, Thomas Laurent and Mathias Beche can be confirmed as Rebellion’s first overall race winners in WEC competition, and the first privateer overall victory in championship history.
Menezes will also be the first American driver to claim the outright win a WEC race.
The two Toyotas dominated the six-hour race, at the time earning a 1-2 finish by more than four laps. Heading into the final hour it looked like the No.7 car would take its first victory of the season, but the issue with the floor left Kobayashi with no option but to relinquish the position to Buemi, who took the checkered flag.
A stewards statement indicated that the race-winning No. 8 “deflected 6mm on the right hand side and 8mm on the left hand side under the specified 200 N load at the front of the skid block.”
For the No. 7 car, “The front part of the skid block deflected 9mm under the specified 2500 N load on both sides of the skid block.”
