Williams technical chief Paddy Lowe has branded the aerodynamic overhau🐓l for 2019 as Formula 1’s most signi🔜ficant rule change since 2009.

Next season front wings will be 200mm wider and 25mm deeper and feature fewer complicated elements as F1 bids to improve t🌜he 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 dಞevices during the post-Hungarian Grand Prix test at the Hungaroring ahead of their iওntroduction next year.

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

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

Lowe sees the regulation changes as an opportunity for Williams to make up some ground on i🐠ts 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 opp🌸ortunity 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 s♉hake-up - could occur again.

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

"Somet🌊hing that teams have said in the past is we'll get back to where we were, but that 🥃feels completely arbitrary in itself.

"You try to pick a sensible level based 🙈on where you start. How accurate is that, and what difference does it make anyway, are two questions I don't rea💞lly 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5最新开奖结果:change their approach.
