Holden’s Final Commodore GTSR W1 Brings Corvette ZR1 Thunder From Down Under

General Motors recently announced that it is killing off its Australian-bred and produced, rear-wheel drive Holden Commodore. For Americans, this means that the Commodore-based, hard-charging Chevrolet SS is also being euthanized.

But Holden isn’t going down without a fight, which is why it is coming out guns blazing with the ultimate version of its four-door hell chariot. Holden Special Vehicles (HSV) has pulled the wraps off the Commodore GTSR W1, which manages to stuff the Corvette ZR1’s epic supercharged LS9 V8 engine under its hood.

For Commodore GTSR W1 duty, the LS9 makes 636 horsepower at 6500 RPM and an earthmoving 601 lb-ft of torque at 3900 RPM. Sending power to the rear wheels is a Tremec TR-6060 6-speed manual transmission (as the petrol gods intended).


HSV has also fitted the Commodore GTSR W1 with high-performance AP Racing steel brakes (sorry, no ceramics here), adjustable SupaShock dampers and Pirelli P Zero Trofeo R tires. Holden says that its swan song will sprint from a standstill to 60 mph in 4.2 seconds and will cover the quarter-mile in 12.1 seconds.

Inside, you’ll find Alcantara covering the steering wheel, gearshift lever and the seating surfaces (with a snazzy diamond pattern). As for the exterior, you’ll find a menacing face, aggressive rocker panels and a carbon fiber-tinged rear deckled spoiler. And you’ll have your choice of colors including Light My Fire Orange, Son of a Gun Grey, Spitfire Green, Phantom Black or Sting Red.

Although we’re sorry to hear that Australians are losing a natural treasure (and by association, Americans with the somewhat unloved Chevrolet SS), the brutish, ham-fisted four-door sedan market is still alive in the U.S. market; even if it has been whittled down to just one entry. The Dodge Charger SRT Hellcat is still available, priced from $65,945. The Charger SRT Hellcat is powered by a 707-horsepower supercharged HEMI V8, covers the quarter-mile in just 11 seconds and can hit a top speed of 204 mph.
