"motoring.com.au has been told HSV is plotting "something big" based on its GTS flagship, which is already Australia's most powerful locally-built car at 430kW/740Nm, and potentially powered by the 476kW/819Nm supercharged 6.2-litre LS9 V8 from the discontinued Chevrolet Corvette ZR1. It's understood HSV won't be reviving the GTS-R name."
