The next-gen cars will be powered by completely new engines that are more heavily based on production units than the current pushrod V8s. The new Ford is a 5.4-litre version of the quad cam Coyote, while the Chevrolet is a 5.7-litre pushrod motor.

There will also be a philosophy change when it comes to teams accessing motors. Until now there has been complete freedom on engine supply, with some teams running their own in-house engine programmes, while others use specialised builders.

However for Gen3 there are just two homologation engine builders – KRE for Chevrolet and Herrod Performance Engines for Ford.

KRE and HPE will then supply motors directly to Supercars, which will run every single unit on its own dyno before randomly allocating them to teams.

“There are only two engine builders and Supercars is going to randomly pick the engines, allocate them to the teams, and away they go,” explained Supercars Head of Motorsport Adrian Burgess.

“There won’t be anyone accusing either of the two engine homologation teams favouring their factory teams.

“We need to build all these engines, make sure they are all within a tolerance that we’re comfortable with, then we’ll randomly select where they go up and down the pitlane.”

Should teams feel there engine isn’t good enough, there will be an avenue to discuss with the builder and have the unit checked by Supercars.
