Drivers have long complained about dirty air and aerowash caused by high downforce levels in Supercars.
It is hoped a reduction in downforce will allow cars to follow each other closely and in theory promote overtaking.
Supercars reduced downforce between the 2019 and 2020 seasons by approximately 12 percent, although the dirty air problem persisted.
With the advent of new regulations, Supercars is taking the opportunity to make wholesale changes.
“One of the biggest things our drivers complain about currently, is not being able to follow the car in front closely at mid-corner on high speed corners and then make a pass at the following corner,” a Supercars spokesperson told Speedcafe.com.
“Less passing means less entertaining racing, which is why we are addressing it. With 400-plus kilograms of downforce on our current cars, it creates a lot of disturbed, or “dirty air” for the following car which is what the drivers are complaining about.
“Coming down to mid-100kgs we believe, and this is being backed up by the work being done in CFD [computational fluid dynamics], will significantly reduce the amount of dirty air generated and therefore improve following conditions and then passing, thus improving the racing.”
Until now, little had been said of the aerodynamic matters related to Gen3 and how much of a downforce reduction could be in order.
Speedcafe.com understands those wings will be used primarily as a parity balancing tool.
Those renders also revealed a new-look front splitter with fenders on either side. It remains unclear whether those elements will make it to the final race-ready models.
The Mustang and Camaro silhouette will also bear a closer resemblance to their road-going counterparts.
That would see the successful applicant or applicants supply Mustang and Camaro bodywork including the roof, boot, doors, quarter panels, mirrors, front and rear bars, front splitter, rear diffuser, rear wing elements, A-, B-, and C-pillars.
