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.
