Performax International recently achieved Australian Design Rule compliance for the United States-built Silverado after completing design, engineering and conversion work in-house at its Sunshine Coast, Queensland, factory.

The main model offered will be the Silverado 2500HD crew-cab four-wheel drive, priced at $123,000 plus on-road costs for a brand-new vehicle with exclusive four-year/120,000 km warranty and four year' roadside assistance.

Other models from the extensive Silverado and sister GMC Sierra range are available on order.

The 2500HD features crew-cab utility bodywork, GM Duramax 6.6 litre V8 turbodiesel power, Allison six-speed automatic transmission with high and low ranges and dashboard-selected four-wheel drive engagement.

Towing capacity with a braked trailer of 4.5 tonnes plus mountainous power puts the Silverado in a class alone for owners with large boats, horse floats and caravans.

Peak engine outputs are 272 kiloWatts at 3,200 rpm and 895 Newtonmetres of torque at 1,600 rpm.

The Allison Adaptive Shift Control gearbox with manual over-ride includes a Tow/Haul mode, which alters shift patterns to maximise engine efficiency in pulling and braking. Tow/Haul mode also engages Grade Braking, which selects a lower gear to assist hill descents even when cruise control is operating.

Performax International General Manager Nick Vandenberg says the 2008 Chevrolet Silverado 2500HD is the answer to the dreams of many heavy-duty and long-distance haulers in Australia.

"The 2008 Silverado is a big step forward in performance, refinement, styling and comfort for this type of ute," Mr Vandenberg said.

"With towing capacity at 4.5 tonnes, it's the big ute many people have been waiting for. We had orders for almost 20 even before the ADR compliance process was completed and now we expect many more from both recreational and business buyers."

"There is no other new vehicle like it on the Australian market, especially at a price within the range of many less capable 4WD wagons."

"The new exterior and interior styling looks great and the cabin provides real comfort, with a spacious rear bench for three large adults, leather upholstery and the comfort and safety items usually found on passenger cars."

The 2008 Chevrolet Silverado is available for purchase directly from Performax International in Gympie, Queensland.

Performax International, formerly Corvette Queensland, has been importing and converting American vehicles for almost 20 years, developing an unequalled reputation for the quality of its engineering work and customer service.

It employs more than 40 people at its Sunshine Coast, Queensland, factory and produces around 200 vehicles a year for Australian roads.
