"When we started looking at the 2021 auto, the primary objective was to enable the cars to race well together", Brawn said.
The next major regulation change is set to be implemented in 2021, with a working group from F1 itself being headed up by managing director of motorsports Ross Brawn.
"What our research showed early on is that the current cars are very bad at following each other".
Formula 1's owners have stated they want the cars to be "more raceable to increase overtaking opportunities" and for driver's skill to be "the predominant factor in the performance of the vehicle".
"The current cars lose up to 50 per cent of their performance once they get to within one or two auto lengths. which means they struggle to race each other", added the Briton.
"We can't eliminate that completely but we can reduce it, so the time differential for one vehicle to attack another can be much less".
"The primary thing we're doing is trying to reduce the amount of performance lost to a following vehicle", Brawn said. So the cars out there at the moment, on our assessment, lose 50 percent when they get right behind. So we set about understanding why that was and how we can improve it. Fairings have also been introduced in front of the rear wheels in order to help tidy up airflow around the tyres. We've had a designer working with the aerodynamic group, so as we've progressed. Previous regulation changes have resulted in unexpected and ugly design elements, and Brawn admits the first season of cars may not look exactly like the concepts. "Next year is an important barometer to see how much impact it has on the ability for the cars to follow".
Zlatan Ibrahimovic scores to reach 500 goals for club and country
However, it wasn't to be for the Californian side, who shipped two more goals in the final 15 minutes to lose the game 5-3. Ibrahimovic was PSG's top goalscorer with 156 goals before Edinson Cavani broke his record in January.
"But there is no guarantee and I think the key thing is to be able to respond quickly when we see things that happen that are unintended".
However, whatever look the sport decides on, Brawn admits that the powers-that-be are hoping it encourages new teams into the sport, while ensuring the current teams remain.
"The encouraging thing is that the teams are now involved with us. They look better but there are a lot of technical reasons why we want them".
"And so there are regular reviews with all of the teams".
"The teams have a limitation on the amount of aero testing they can do, but the FIA has granted them some extra time to work on this project, so there is a great incentive to find the best solution. I'm pleased to say we're at about 80 percent", Brawn said.
Lewis Hamilton is a fan of the proposed new look.
