Wil­liams suf­fers Drsre­lated stalls

Autosport (UK) - - RACE CENTRE | BRITISH GP -

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.
