Gen3 Gen3 made its debut, replacing the Car of the Future regulations that débuted in
2013, with regulations designed to lower costs of a standard Supercar. It was due to debut midway through 2022, but due to ongoing challenges with international supply chains and domestic disruptions caused by the
COVID-19 pandemic, it was delayed to 2023. The regulations introduced more
controlled components into the cars to address the rising costs of maintaining a car. The pedal kit, brake kit and wheels became control components, with tenders needing the rims to be 'finger friendly' for pit crew during a pit stop. The roll cage lowered by 100mm to be suited to coupes, after the controversy surrounding the
Ford Mustang GT, which required the roof to be stretched beyond the dimensions of its road-going counterpart to fit the Car of the Future chassis. Supercars manufactured the roll cage in
kit form for teams that do not have the budget to build one themselves. The engines on Gen3 were overhauled, with pushrod engines replaced with fuel-injected, V8 engines, with the Camaro running a 5.7 Litre
LTR V8, while the Mustang will run a 5.4 Litre
Coyote V8. This is intended to modernise the engine and significantly reduce costs of building and maintaining them. Aerodynamic downforce was cut by 67% to encourage closer racing and easier overtaking after complaints from drivers about dirty air and aerowash from current Gen2 cars. Minimum weight was decreased from 1,400 kg to 1,335 kg, with a 95 kg minimum of driver and seat weight combination. Later, it was increased to 1,340 kg from the
Sandown 500.
Triple Eight Race Engineering oversaw the development of the
Chevrolet Camaro ZL1 as a replacement for the
Holden ZB Commodore. The Camaro ZL1 was chosen after parent company
General Motors decided to discontinue the Holden brand and shut down production of the Commodore.
Dick Johnson Racing oversaw the development of the
S650 Mustang.
Other changes A new E75 fuel blend was introduced, down from E85 that was used from 2009, while utilising more renewable bio fuels to lower carbon emissions. Ahead of the
Perth SuperSprint an LED display was added to the windscreen to show information such as a driver's position in the race, practice, or qualifying session to spectators. Ahead of the
Gold Coast 500 a Full Course Yellow system was implemented, although the system saw no use during the event itself. == Results and standings ==
