Supercars, homologation teams hail collaborative test efforts

Supercars and the three homologation teams have hailed the collaborative efforts that helped deliver aerodynamic parity across the three cars in the United States.

Aerodynamic parity has been achieved between the new Toyota GR Supra, Ford Mustang and Chevrolet Camaro following a mammoth testing program at the Windshear facility in North Carolina.

Representatives from Supercars, Walkinshaw Andretti United (Toyota), Triple Eight Race Engineering (Ford) and Team 18 (General Motors) jetted out for the US shortly after the 2025 season concluded in Adelaide.

There, all parties worked 18-plus hour days at Windshear in the effort to remove any discrepancies between the three cars. On Sunday (AEST), Supercars and the homologation teams celebrated parity between the three cars.

“There were some stressful moments, and they're particularly amplified when you're here 18 hours a day,” Supercars Chief Motorsport Officer Tim Edwards said.

“You can imagine when you're getting to hours 17 and 18, everybody’s a little bit more on edge. And to pull off what we did and have everybody working collaboratively.

“Everybody mucked in, and that's one of the real positives that comes out of a test like this.”

Much of the focus was getting the new Supra up to speed, but such was the combined effort, that the Camaro and Ford were also adjusted throughout the testing to ensure no stones were left unturned.

“I’m actually a little bit overwhelmed by it, to be honest. It's been a been a huge few days, with targets moving and car changes and stuff like that,” WAU Team Principal Carl Faux said.

“We had 18 hours in the tunnel for the Ford, 12 and a half hours in the tunnel for the GM, and [the Toyota] managed to do it in 24 hours and that's with a target change at 12 hours in.

“I'm stoked for the team. I'm glad that this is over and can't wait to get to the race track.”

It was a second trip to Windshear for Triple Eight, although this time, the championship-winning team was charged with overseeing development of the Ford.

Triple Eight Team Manager Mark Dutton insisted the common goal between all parties was achieving parity, so the talking can be done on track.

“Everyone had to burn the midnight oil,” Dutton said.

“But the really cool thing is everyone worked together really well. You can work together here because everyone has a common goal.

“The common goal is having parity — we don't want that to be a dirty word. We want to put it behind us and then do our racing on the race track.”

It was a point echoed by Team 18 Team Principal Adrian Burgess, who reiterated that the homologation teams are working together to deliver a product that is for the betterment of the sport.

“I think it's been a really encouraging collaborative approach,” Burgess said.

“It’s a testament to the collaborative effort of all the engineers, all the mechanics, and the tremendous support from the guys at Windshear.

“We've all been looking at each other's cars, inspecting them, looking at the gaps, pushing here, pushing there, making sure that the preparation of the cars is all the same.

“I think when you are the HT for any of the three brands, you know that you wear the Supercars badge as well and you've got a responsibility.

“We all kept everybody under control and accountable for everything we're doing. So, very happy with the effort, very happy how everyone worked together.

“When we're here, we're not individual teams, we're working for the series. Very happy with how it's gone, now just looking forward to going racing now.”

Attention now turns to the 2026 Repco Supercars Championship, which commences in Sydney on February 20-22.
