A concept idea created by F1's managing director of motorsport Ross Brawn has been leaked across social media platforms ahead of this weekend's Singapore race weekend.Brawn's vision for the new look cars, set for 2021, was delivered in a 'tech talk' seminar held by race organisers in Singapore on Wednesday night.An overhaul of car rules set to be introduced in three years time has led to ideas of changes to the aesthetics of recent Formula One cars.Despite Wednesday's seminar being behind close doors, images of the concept car were soon doing the rounds across popular social media sites, allowing fans a glimpse into what may be on their screens come 2021.The changes, which are designed to make the sport more entertaining and attractive to fans, were shown on a mock Ferrari car and included many differences to this years' cars.Perhaps most notably, the concept featured the new 18-inch wheels which form part of the future F1 tyre tender contract.Other changes include less complicated bodywork around the sidepods and the coming together of the engine cover and rear wing which appear joined.Perhaps for safety, integration between the rear wing endplates around the rear wheel are evident, designed to stop cars being launched on top of each other after a collision.

Changes to the front wings can also be seen, with their design seemingly made simpler, with more aggressive sculpted endplates, extending higher.

Around the sidepods, bodywork appears less complicated, and the joining of the engine cover and rear wing could suggest an extension to the DRS system, despite Brawn's desire to remove the overtaking tool.

However, with new Formula One owner Liberty Media continuing to work with teams on the plans for 2021, it is unclear how much of this concept will be seen on tracks in three years time.
