Williams suffers Drsrelated stalls
The high-speed spins suffered by both Williams Formula 1 drivers in British Grand Prix qualifying were caused by an aerodynamic stall and led to both drivers starting from the pitlane after switching to an older-specification rear wing. The cause has been traced to a stall developing at the floor of the FW41 after DRS has been used and then deactivated. Williams chief technical officer Paddy Lowe admitted this problem has an impact on the development process. “It’s a very unwanted… not delay, but it’s not quite on the track we intended,”said Lowe. “This rear wing was part of our wider programme to get back to where we wanted to be. “I’m not convinced that it’s the rear wing itself – it’s a matter of how it’s functioning together with the floor.” Lowe admitted it had first emerged in Fp1“on one car”, but“we diagnosed something else to be the cause of it – that’s obviously a mistake”. Stroll and Sirotkin went on to finish 13th and 14th, last of the runners, in the race.
