Supercars' next generation of cars have gone back-to-the-future with the new Camaros and Mustangs closely resembling road vehicles.
Set to be rolled out for the 2023 season, the Gen3 cars have been unveiled at Mount Panorama before Sunday's season-ending Bathurst 1000.
The Chevrolet and Ford prototypes bare a closer visual connection between race and road vehicles than the current model cars.
They also come with a signature V8 engine sound in a nod to the category's former name, before it was shortened to simply Supercars.
"These are incredible looking race cars," Supercars boss Sean Seamer said.
"The motorsport and motoring worlds have been watching this announcement very closely as it is a massive opportunity for our sport to step up on several levels and attract a wider audience.
"Both the Mustang and Camaro give a nod to the Supercar of the past, with as much attention given to the design and appearance of the cars as the new technologies.
"The Ford Mustang and GM Camaro are the first chapter of our new era."
After General Motors retired the Holden brand last year, there has been an awkward transition phase from the iconic Commodore to the Camaro.
Teams have been racing Commodores in this year's championship, just without the official Holden-Ford rivalry that has dominated the Australian motor sport landscape for more than 50 years.
"Our company has a proud history of racing in the Australian Touring Car Championship and in Supercars for over five decades," Chevrolet performance and racing boss Jim Campbell said.
"We're excited to announce a new chapter in the history of Australian motor sports with the introduction of Chevrolet Racing and the all-new Gen3 Camaro ZL1 for Supercars."
