One of the rarest and most desirable Australian performance cars ever produced has been listed for sale, with the final HSV GTSR W1 Maloo now being offered to buyers for the first time.

The 2017 HSV GTSR W1 Maloo, known as build E005, is one of just six examples produced by Walkinshaw Performance and is believed to be the final W1-specification HSV completed at the company’s former facility.

Offered through Sydney-based automotive specialist Chrome Temple, the ultra-rare ute has had just one owner and remains unregistered, with nothing but delivery kilometres on its odometer and its original factory wrapping and stickers still in place.

The story of the W1 Maloo dates back to 2017, when HSV was preparing to farewell Australian-built Commodore production with its most powerful model yet. The GTSR W1 sedan was powered by a hand-built 6.2-litre supercharged LS9 V8, originally developed for the Chevrolet Corvette ZR1, producing an enormous 474kW of power and 815Nm of torque.

Paired exclusively with a six-speed manual transmission, it also featured SupaShock suspension, AP Racing brakes and wider front guards.

However, while HSV considered producing a W1 version of its Maloo ute, the cost of engineering and certifying such a limited production run ultimately ruled it out. Instead, Walkinshaw Performance privately commissioned six W1-specification Maloos using existing GTSR Maloo donor vehicles, making them considerably rarer than the W1 sedan.

The example now being offered for sale began life as a Heron White GTSR Maloo in April 2017, before being converted to W1 specification by Walkinshaw in 2023. It features the same 474kW supercharged V8 and six-speed manual transmission as the W1 sedan, along with W1 badging, a shadow chrome exhaust surround and a Jet Black interior with Alcantara upholstery.

Its authenticity is supported by a Walkinshaw Certificate of Authentication, engineering approval, build receipts and photographic documentation of the conversion. The vehicle also retains its original documentation, two W1 keys and a specially numbered W1 Maloo car cover.

Chrome Temple hasn’t disclosed an asking price, instead listing the vehicle as price on application. Given that just six examples were completed, and that this particular vehicle remains in virtually untouched condition, it’s likely to attract significant interest from collectors of Australian performance cars.

With Holden and HSV production now firmly in the history books, the opportunity to acquire one of the final expressions of Australia’s homegrown V8 performance era is becoming increasingly rare.
