Supra to join Camaro, Mustang for wind tunnel testing in USA

Supercars can confirm all three Gen3 Supercars — the Chevrolet Camaro, Ford Mustang and incoming Toyota GR Supra — will be shipped to the United States for aerodynamic testing at the Windshear wind tunnel facility in early December.

It marks the first time in the sport’s history that all three manufacturers will be tested together in a wind tunnel environment, ahead of Toyota’s full-time Supercars debut in 2026.

The test is being coordinated by Supercars’ technical department, in partnership with the category’s three 2026 homologation teams: Walkinshaw Andretti United (Toyota), Team 18 (Chevrolet), Triple Eight Race Engineering (Ford).

The confirmation of the wind tunnel program for all three manufacturers follows a thrilling start to the 2025 Repco Supercars Championship, which has already delivered eight different race winners, 15 different podium finishers, and nine different pole sitters from 22 races.

Two of the three closest finishes in ATCC/Supercars history have also occurred this year, highlighting the competitive health of the sport.

Supercars Chief Motorsport Officer Tim Edwards said: “We’re incredibly proud of how competitive the racing has been this year. We’ve seen an exceptional spread of winners from across the field and some of the closest finishes in our history,” Edwards said.

“Wind tunnel testing all three cars together will give us additional data to add to what we will have already collected and help further validate and fine-tune our aerodynamic parity processes.

“Ahead of this exciting new chapter for the sport, this testing will only strengthen our knowledge base ahead of Toyota’s debut in 2026.”

Windshear, located in North Carolina, is one of the world’s most advanced motorsport testing facilities. Its full-scale rolling road and temperature-controlled environment allow teams to measure downforce and drag in conditions that can’t be replicated on track or at an airfield.

The testing will provide parity data for all three models ahead of the 2026 season, with each car built to a “race-ready” standard and verified by Supercars before and after the test.

“This process gives us complete confidence in the technical foundations of the Championship heading into next year,” Edwards said.

“The teams are working together, the cars will be scanned and checked before and after the tunnel runs, and the data we collect will help deliver the close, hard racing our fans expect.”

Supercars previously used the Windshear facility in December 2023 to test the Gen3 Mustang and Camaro ahead of their second season. This next phase will be the most comprehensive aerodynamic parity test the sport has undertaken.

The cars will return to Australia in early 2026, with final specifications derived from the wind tunnel testing implemented before the opening round of the new Repco Supercars Championship.
