Final HSV With ZR1’s 638 HP Engine To Be Dubbed GTS-R W1

The final HSV branded Holden Commodore-based model is set to be dubbed the GTS-R W1, reports Australian publication Motoring.

Based around the soon-to-be-killed 2017 Commodore, the GTS-R W1 will be HSV’s swansong and the most powerful, fast and expensive production car it has ever produced. It will also be the fastest production car ever built in Australia.

Power for the HSV GTS-R W1 will come courtesy of the 6.2-liter supercharged LS9 V8 engine of the previous-generation Chevrolet Corvette ZR1. When installed into the ZR1, this insane powertrain delivers 638 hp and 820 Nm (604 lb-ft) of torque. While the final power figures for the HSV model aren’t yet known, they’re expected to be at least the same as the ZR1 or could be raised slightly.

Whatever the case may be, the model should be able to sprint to 100 km/h (62mph) in around 4 seconds and rocket down the quarter mile in just 12 seconds. These impressive times will come despite the fact the car will only be offered in rear-wheel drive and with a six-speed manual transmission.

Elsewhere, the GTS-R W1 will include a set of bespoke dampers design and manufactured in Adelaide by Supashock. They will include similar technology to the shocks of the current Commodore VF Supercars.

The model will be sold exclusively in Australia and limited to around 250 examples, starting at $170,000 AUD ($128,000 Stateside).
