The 2018 Commodore Supercar shape is based around the new series Commodore model set for release next year. The new model will be the first-ever fully imported Commodore model .

The Supercars race version, currently under development by Holden and its official factory racing team, Triple Eight Race Engineering, will by homologated with the current 5.0-litre V8 engine for the 2018 season only.

From 2019 all Commodore Supercars will be powered by the new twin-turbocharged V6 engine currently being developed for Supercars’ Gen 2 regulations in General Motors Performance and Racing Centre in Michigan.

But the new V6 engine could be seen in action next year, as Triple Eight Race Engineering will seek approval from Supercars to run a V6-powered Commodore as a wild card entry at selected rounds next season before a full rollout in 2019.
