Williams is running the high downforce rear wing specification which it was forced to remove during the British Grand Prix weekend after it caused a series of spins.

Both the team’s drivers suffered high-speed spins when they closed DRS due to the airflow stalling. It chose to the rear wing for an older specification after qualifying, which meant both drivers had to start the race from the pits.

Following other changes to its car in Hockenheim it has now reintroduced the high-downforce rear wing for this weekend’s race in Hungary.

Sergey Sirotkin confirmed the wing is now working as it should. “We don’t see so far any single issue of what we had in Silverstone,” he said.

The team has been able to solve the problem with only minor changes, Sirotkin told RaceFans. “A little bit around the floor. A little bit of set-up of the wing itself. A few very little things but altogether seems like it makes the job.”

Chief technical officer Paddy Lowe said the problem which occurred while using DRS at Silverstone was a “side effect” of changes the team had made elsewhere on the car to improve the performance of its FW41.

“The problem we had in Silverstone was primarily a result of some change we made to the floor in the diffuser area, some fences,” he explained.

“In the position we’re in we were very aggressively, let’s say, with our attempts to improve performance. We used Fridays intensively to test parts and work with new parts.

“In Silverstone we made a step on Friday with modifications to the diffuser which were actually an improvement in cornering, took them forward to the race, but they had a side-effect of putting the car intermittently into stall in relation to use of DRS. It was effectively a side-effect of a step we’d introduced for cornering performance.

“So very unfortunate, very visible consequences to have to correct that for the race starting with cars in the pit lane. but we had no choice. It was something that had been entirely unexpected as a side-effect.”
