All five V8 Supercars marques will have the opportunity to re-homologate their aerodynamic packages prior to the 2015 season, the category has announced.

The move follows an aerodynamic process evaluation test at Oakey, Queensland, in August overseen by recently appointed V8 Supercars technical director David Stuart.

V8 Supercars’ aero testing procedures have been under the microscope since January when a troubled homologation test between the new Volvo S60, revised Nissan Altima and baseline Ford Falcon created significant doubts over parity.

A statement from V8 Supercars says that the Oakey test “ratified the existing homologation process but also led to advances that will be applied in future aerodynamic testing”.

Despite the revisions to the process the re-homologation remains optional, as it was for Nissan and Mercedes-Benz in January, 2014.

“After consultation with the Commission appointed Aerodynamic Committee, the VCAT (V8 Supercars Aerodynamic Testing) is now conducted with additional equipment to strengthen the process,” V8 Supercars Director of Sport Damien White said.

“After re-testing, and validating what we applied as aero parity this year, we considered it appropriate to allow the homologation teams the chance to understand what additional information is used now in that process.

“At the end of the day they will have to remain within the same parity window, however sometimes manufacturers have different agendas in terms of how their race variant looks, and this is an opportunity to accommodate that through the homologation teams.”

V8 Supercars says that the homologation teams, which consist of Ford Performance Racing, the Holden Racing Team, Volvo Polestar Racing, Erebus Motorsport and Nissan Motorsport, must officially inform the category of their intentions by October 3.

It remains unclear whether there will be any new models to homologate for next season, with Ford Performance Racing still waiting for the green light on its FG X program.
