Russell locked up and crashed during the virtual safety car period on lap 27, while Kubica was called to return to the pits only a lap later. Williams’ Senior Race Engineer Dave Robson has now explained the reason behind Russell’s lockup.
“We found an issue with the wheel nut retainer on George’s car, which led to the front-right wheel not sitting perfectly,” said Robson.
“This caused a lock-up under braking.
“The design is very mature and well-proven. The remaining inventory will be inspected thoroughly, and we do not anticipate a repeat of the issue.”
Meanwhile, Kubica’s retirement was entirely the team’s decision. After the race Williams explained the Pole was retired “to conserve parts ahead of the upcoming races”. Robson now gives more details on the decision.
“Unfortunately, we were forced to retire Robert’s car due to the amount of accident damage we sustained in the Singapore-Russia back-to-back races in order to protect ourselves going into the next events.
“The team has worked extremely hard to ensure race quantities have improved ahead of Japan and the final races,” concluded Robson.
