Camaro ZL1

The Chevrolet Camaro ZL1 is General Motors' current Supercars car, introduced for 2023 under the Gen3 regulations. It replaced the Holden ZB Commodore after the Holden brand was retired — the first time a Chevrolet, rather than a Holden, has carried GM's colours in the category. It races the Ford Mustang S650.

From Holden to Chevrolet

With Holden wound down, GM chose the Camaro, badged as a Chevrolet and homologated by Triple Eight Race Engineering — the same team that had developed the Commodore. In a familiar Supercars twist, the road-going Camaro went out of production not long after the race car arrived.

The Gen3 package

Gen3 lowered downforce, standardised more of the car (including a control brake package) and moved to production-based engines. The Camaro runs a naturally aspirated, pushrod (OHV) V8 derived from Chevrolet's LT/LS architecture, widely reported at around 5.7 litres (approximate — not confirmed here against the Gen3 technical rules), through the control rear-mounted six-speed sequential transaxle, on the Dunlop control tyre and the common Gen3 control chassis.

Body & aero

The ZL1 puts the two-door Camaro coupe on the shared control chassis — part of Gen3's move back to two-door coupes after years of four-door Falcons and Commodores. The low-downforce aero (front splitter, undertray, rear wing) is a controlled package set by the rules for parity between the two marques.
