A new Supercars era is about to get underway.
The Gen3 ruleset will debut in the 2023 season, as the touring series undergoes one of the largest changes in its history.
Following Holden’s withdrawal from the competition last year, the Chevrolet Camaro and Ford Mustang will be the two cars of choice for this campaign.
The Sporting News takes a look at the new Gen3 design and ruleset.
Gen3 Supercars design
Both the Camaro and Mustang are noticeably different from the current Gen2 design, with greater similarity to their ‘road-going equivalents’.
The 2023 cars have been crafted “with an eye on increased road relevance and improved racing,” according to Supercars.com.
The design is similar to that of a two-door muscle car, combined with a clean-sheet chassis configuration.
Take a look at the Gen3 Mustang in action at last year’s Bathurst 1000 below:
Gen3 Supercars specifications
Gen3 marks the biggest change to the Australian racing series since the implementation of V8-powered Commodores and Ford Falcons in the 1990s.
To ensure the new cars act more like road cars, Supercars are aiming to reduce downforce by more than 65 per cent.
This will also place more weight on a driver’s skill and lead to more overtaking opportunities.

There is also significant change when it comes to engine capacity – gone are the days of 5.0 litre V8 engines.
The Camaro will run on a single camshaft General Motors engine, with two valves per cylinder.
Ford’s engine, on the other hand, features four camshafts with four valves per cylinder.
The stick shift gear system – which was a popular component of the Gen2 cars – will continue to feature in the new model.
Are Gen3 Supercars faster than Gen 2?
The Gen3 car is expected to reach a top speed similar to its predecessor.
Whilst the significant reduction of downforce suggests the new design would be faster, the engine adjustments will counteract that effect.
In fact, Supercars officials have made a deliberate effort to prevent cars from exceeding 300 km/h.
“We have always worked on the fact that we don’t want the cars going over 300 km/h down Conrod [Straight, at Mount Panorama],” Supercars head of motorsport Adrian Burgess told Speedcafe.com.
“So when we have targeted the downforce number that we believe we can get to and when we’ve worked on our projected minimum weight of the car, you also factor in where you would like to be in terms of manufacturers being able to bring a wider range of engine configurations to us.”
Supercars 2023 calendar and schedule
The 2023 Supercars season will begin in the Hunter, with the Newcastle 500 returning to the calendar after being removed in 2022 due to COVID-19 concerns.
Supercars will then race at the Formula 1 Australian Grand Prix, with a trip to Albert Park scheduled for late March/early April.
Notably, this season features multiple endurance races for the first time since 2019. Sandown has had its race length extended, and will take place in September.
The famous Bathurst 1000 will be held in its traditional early-October slot as the tenth race of the season.
Fresh off a five-year contract extension, the Adelaide 500 will then wrap up the 2023 campaign.
