Alpine: Flexi-wing push motivated by weight saving
With new more durable pull again assessments being launched from the French Grand Prix later this month, F1 groups may have a remaining likelihood to run with their earlier versatile designs for this weekend’s race in Baku.
Nevertheless, there stays the specter of a protest for those who do, and it isn’t not possible that the FIA might take unilateral motion itself if it feels that groups are pushing the boundaries an excessive amount of.
Alpine is certainly one of many outfits that must make modifications to its rear wing for the French Grand Prix, and it says the push by groups on this space was not merely concerning the wings flexing again to scale back drag on the straights.
“The deflections of wings are largely linked to weight saving actually,” he mentioned. “I imply we’re all preventing the burden restrict and particularly on the rear of the automobile.
“There may be an incentive not solely to have the automobile as mild as doable and put as a lot ballast on the backside as doable for centre of gravity, but additionally to run extra ballast on the entrance of the automobile, and the entrance being within the entrance of the ground, for weight distribution functions.
“The worst place on a automobile to have weight is within the rear wing as a result of it’s excessive up and it’s in the back of the automobile. So it’s one of many areas we’re pushing the toughest for weight saving. And once you save weight you make a automobile that may be a bit lighter and a bit much less immune to load.”
Whereas Aston Martin prompt lately that flexi-wings might be price as a lot as half a second per lap of efficiency, different groups usually are not so satisfied.

Crimson Bull crew boss Christian Horner reckons that the wings solely ship a achieve of round one tenth of a second.
“It is marginal since you compromise different elements,” he mentioned. “I feel in a simulated world, you are speaking between half a tenth and three quarters of a tenth of a second right here. So it is extraordinarily marginal.
“I’ve heard numbers of half a second being quoted, however I feel you’ll be able to see right here that our wings arguably are flexing lower than a Mercedes rear wing. So it actually wasn’t half a second of lap time delta.
“I feel it is all been a bit of bit overhyped within the media. Like all this stuff there may be by no means a silver bullet. And I feel that it’s good to have a automobile working effectively, you want every part: engine, chassis; automobile dynamics, and aerodynamics all working in concord. And it is by no means one single issue.”

Budkowski concurred that the shift to stiffer wings for Paul Ricard wouldn’t serve to shake up the F1 order.
“We’ll adapt to it,” he mentioned. “It can price a little bit of efficiency, it can price us some weight for certain, and the centre of gravity, weight distribution. And doubtlessly perhaps a little bit of aero efficiency if there was some drag-saving associated to it. However that may be very small on the finish of the day.”
