Wow I hope they plan on running a better motor than the current
Sludgetech!!!!!! I feel extremely dirty saying it but holden v6 leaves alot to be desired to point where most critics say if you want a 6 buy a f*** if you want an 8 buy a holden!!!!!!
One does have to wonder Greg id actually like to see production racing as it raises bar and promotes need for r&d just think of type of gm's which would be available to use if they where competing with mercedes c63 in std form .....
Unfortunately everyone would cry poor me poor me and the restrictions would come into play? I think this killed the sport to begin with. Just my 20c worth
On the other hand im partial to other gm cars

ie corvette camaro Cadillac lol
