Supercars models to undergo further aero analysis

Supercars is set carry out further aero analysis to greater understand the aerodynamic strengths and weaknesses of the current models.

Speedcafe.com understands that Supercars will conduct the test with examples of the Ford Mustang, Holden ZB Commodore and Nissan Altima between the Tyrepower Tasmania SuperSprint (this weekend) and WD-40 Phillip Island SuperSprint (following weekend) rounds.

News of the test arrives amid a parity debate concerning the new-for-2019 Mustang which has triggered claims from rival teams that the car has a centre of gravity (CoG) and aero advantage.

Supercars has already mandated CoG tweaks for the Mustang and ZB Commodore in time for the Symmons Plains round following the results of a two-day test involving 10 Supercars at Kelly Racing.

A redistribution of ballast has been undertaken while the Nissan Altima remains unchanged.

However, calls claiming that the Mustang’s larger rear wing endplates and flat edged front splitter, which are within the rules, offer an aero advantage through corners are believed to be among the reasons leading to Supercars initiating more thorough aero analysis.

This arrives after Supercars signed off the Mustang’s aero package last year after the category’s mandatory VCAT aero testing, which is required to be undertaken by all new models to achieve homologation.

Ford’s new weapon successfully completed the process which included several days of straight line running at Temora airfield.

It has previously been stated that the test produced the closest aero results ever across the Mustang, ZB Commodore and Altima models.
