The 2018 season will see Holden continue using its current naturally-aspirated V8 engine, which has been a huge success for Holden teams.
Work on Holden's twin-turbocharged V6 race engine, which meets Supercars' Gen 2 regulations, is currently being undertaken in Pontiac, Michigan, at the General Motors Performance and Racing Center.
Despite work being undertaken on the engine, Triple Eight Race Engineering will seek approval from Supercars to run a V6 Commodore supercar as a wild card entry next season before the full rollout in 2019.
Other Holden teams will also have access to the V6 engine for the 2019 season as part of a leasing program.
Holden says the staggered introduction means Holden and Triple Eight Race Engineering can assist Supercars' technical department with development of programs to ensure the turbocharged V6 can maintain the same levels of performance as the V8.
Supercars Australia CEO James Warburton applauded Holden on the engine development program for the next-generation Commodore.
“It is a pragmatic and sensible approach by Holden and Triple Eight Race Engineering in introducing the new Commodore and a twin-turbocharged V6 powered engine to the sport,” Warburton said.
“Importantly it is a win for all the current Teams in terms of the simplicity and market relevance for an easy transition to the new Commodore in 2018.
“This phased introduction sets a clear path forward for not only Holden, but existing and new manufacturers in the sport,” said Warburton.
