HOLDEN Special Vehicles has teased it is about to reveal a tyre-shredding, 476kW GTS-R badged tribute to the rear-drive V8 formula that has shaped it for the last three decades.

The specialist carmaker teased on Twitter it would reveal its 2017 model line-up – the last to be based on the locally built Commodore – tomorrow. The post, which read “Stop EVERYTHING! Our 2017 range is coming”, included a tightly cropped image of a red brake calliper and two spokes of a rim.

Wheels believes the return of the GTS-R badge will be a big part of the announcement, which should include a range-topping variant called the GTS-R W1, expected to be powered by the 6.2-litre supercharged LS9 V8 found in the Chevrolet Corvette and Camaro.

What we understand is the GTS-R W1 was spied without any camouflage earlier this year shortly after separate images of what appeared to be the 2017 range were snapped.

Judging by the camouflaging, there will be visual tweaks to the front, side and rear of the cars, as well as new colours, and rims.

Wheels has covered the top-secret development of the GTS-R W1 extensively since HSV first approved the project. We previously reported that the W1 will be powered by the Chevrolet Corvette ZR1’s LS9 engine, with a power output in the region of 476kW and a massive peak torque number of 820Nm. The cost? It’s rumoured to be as high as $170,000, which would make the GTS-R W1 the most expensive and powerful Holden Commodore ever made.

Just a reminder: HSV’s tweet states the range will be unveiled just after midnight tonight. Make sure you check back at WheelsMag.com.au for all the news and details of the updated HSV range.
