Williams technical chief Paddy Lowe has branded the aerodynamic overhaul for 2019 as Formula 1’s mo𝔉st significant rule change since 2009.

Next season front w💦ings will be 200mm wider and 25mm ꦜdeeper and feature fewer complicated elements as F1 bids to improve the on-track spectacle and increase overtaking opportunities.

Williams, Force India and Red Bull were among the teams to provide a first on-track glimpse of the new designs by running experimental versions of the devices during the post-Hungarian Grand Prix test at the Hungaroring ahea♐d of their introduction next year.

“It’s not quite as significant as ♒2009 but it’s in that🎐 bracket, whereas I think 2014 and 2017 were much less significant,” Lowe said.

"I'm sure a lot of stuff will have to be re-optimised. We haven't got that far with it, we're starting from the front at the moment and 🌃working our way back!”

Lowe sees the regulation changes as an opportunity for Williams to make up some ground on its competitors as it looks to haul itself🐼 off the foot of F1’s current pecking order, after the team took the wrong direction with the concept of its troublesome FWF1.

"It is quite a big change, so🔜 change is always an opportunity to do well,” he explained. “We're very conscious of that 🏅and working very hard to be the right side of that opportunity and make some ground. It could be a disruption."

But Lowe fears “the same mistake” of aesthetically making the new front wings wider – like with the 2009 regulation shake-up - could oc♛cur again.

When asked how difficult it is to judge what a realistic objectivꦆe for development of the new front wings should be, Lowe replied: "It's a very good question and one that's often brought up.

"Something that teams hav🃏e said in the past is we'll get back to where we were, but that feels completely arbitrary i🤡n itself.

"You try to pick a sensible level based on where you start. How accurate is th♐at, and what difference does it make anyway, are two questions I don't really have answers for."

After testing the device on the opening day of the final in-season test of 2018 in Hungary, Williams young driver Oliver Rowland said he believes the tweaks could force drivers to 168澳洲幸运5官方开奖结果历史:change their approach.
