Supercars has completed the opening day of its critical week-long VCAT of the new Gen3 cars.

The new-look Ford Mustang and Chevrolet Camaro took to the tarmac at Wellcamp Airport near Toowoomba today to begin five days of Vehicle Control Aerodynamic Testing.

The VCAT is taking place for Supercars to ensure aerodynamic parity between the two models that will debut at the Newcastle 500 in March next year and kick off a new era for the category.

The five-day program involves the cars doing a number of straight-line runs with sensors measuring the aerodynamic efficiency, performance and drag of the competing cars across a range of different speeds, ride heights and set-ups.

The first Gen3 VCAT was held back in June last year, but this will be the first time the Camaro and the recently released Seventh Generation Mustang have tested alongside one another.

Staff from Supercars, Triple Eight Race Engineering and Dick Johnson Racing are working big hours with staff arriving as early as 4:00am to get the cars on track two hours later.

Once the VCAT is complete on Friday, the numbers and data will be analysed and Supercars will approve the final specifications to get teams ready for 2023.
