Ferrari handed key warning over radical F1 rear wing

Oliver Bearman has warned Ferrari that its radical F1 rear wing design could be too "heavy" - hence why rivals didn't follow the design.

On Thursday, Lewis Hamilton showed off an 'upside down' design when the active aerodynamics were being used, with the flap rotating through 270 degrees when opening and closing. 

With the exception of Alpine, which has opted for a collapsed design, the other nine teams have all gone for a DRS-style opening when straight line mode is active.

Ferrari only used the design during the morning session on Thursday, with Hamilton reverting to a standard design for the rest of his running, with the FIA determining the design to be legal and within the rules.

Team boss Fred Vasseur remained coy when questioned about the design, which could be on the car for some grands prix. 

However, Haas driver Bearman has warned that the design, although "super innovative", could have drawbacks.

"Yeah, I saw it, and it looks cool, but it is heavy as well," Bearman told media, including RacingNews365. 

"I think everyone has considered it, including ourselves, but there is always a compromise to be made on these things.

"I was actually behind Lewis, and I saw it, and I was like: 'What happened?' 

"I thought it was broken, but honestly, it is super innovative, and it looks pretty slick as well.

"So if it works on track, then they've done something right, that's for sure."
