With testing of the Gen 3 Australian Supercars package well underway ahead of the cars’ competitive debut in 2022, the championship has released a series of videos giving an overview of the new engine packages that will be used by Ford and GM teams.
With a focus on cost cutting across the board, the new engines – based on GM’s small block and Ford’s Coyote platform – are far closer to production units than the outgoing 5-liter motors, which are almost entirely bespoke.
Notably, due to the performance balanced nature of Supercars, the GM engine will displace 5.7 liters while the Ford will be 5.4 liters, on account of the fact the former is a two-valve unit and the latter a four-valve DOHC design.
The engines will have a lower power output than their predecessors, in the region of 600bhp compared with the 659bhp they currently have. Running life will also be extended, currently engines need a tear down every 4,000km; the initial target for the new units is 5,000km intervals which will eventually be extended to 10,000km.
