While the Chevrolet SS exported to America is actually the Australian Holden Commodore underneath, the muscle sedan down under has tumultuous future – and one bright development might include significant power.
While General Motors has decided to pull the plug on Australian production starting with 2017, a recent report has the Holden Commodore actually gaining an astonishing drivetrain – the one that sparked love affairs in the C6 Corvette ZR1. Actually, the Commodore already has a top performance variant manufactured by HSV that uses the 580-horsepower 6.2-liter LSA V-8 engine sourced from the fifth-gen Camaro ZL1and previous Cadillac CTS-V units. Called the GTS, the model is also the most powerful production car in Australia. Accoridng to company sources cited by Australian publication Drive, the HSV are now working on a remastered Commodore to feature the C6 Corvette ZR1 6.2-liter LS9 V8 engine. The mill, available in crate form, is able to churn out 638 hp and could be easily mated to the Commodore chassis. It also looks more prone to the switch than GM’s newer LT V8s such as the LT-4 that delivers 650 HP in the C7 Corvette Z06.
It also appears HSV wants to deliver the model as a celebration of the Holden Commodore end of production in Australia, with HSV being a semi-official tuner for the brand. Because of the production end, most likely the model’s tuned high-performance offer would also be highly limited, which could render it attractive to Aussie collectors. Details claim the current GTS – which already has a dynamic mode selector, an electronic rear differential and magnetic ride suspension – would also gain ZR1’s carbon-ceramic Brembo brakes and most likely an extraterrestrial body makeover.
