Australia’s most expensive car, the HRT 427

A Holden HRT-427 has just become the most expensive Australian car ever sold, fetching a price tag of $920,000 - well beyond the previous $750,000 price payed for a Ford Falcon 1971 GTHO Phase III.


One of only two ever made by Holden for testing and touring motor shows, the near million dollar bid was placed by a bloke in shorts and thongs known only as 'Chooka'.

Based on a Corvette C5R race engine, the HRT-427 is powered by a 417kW 7.0-litre V8 engine - hence the namesake.

No expense was spared for the HRT 427, combining a heavy-duty 900Nm clutch mated to a custom T56 six-speed manual gearbox handbuilt by Tremec for HSV, AP Racing six-piston brake package, half rollcage and Sparco Pro 2000 driving seats as used in the British Touring Car Championship.

Along with the deletion of the audio and air-conditioning systems, carbon fibre was used extensively for a 100kg weight reduction over the standard HSV GTS Coupe, tipping the scales at just 1575kg.

After it became apparent to Holden that the high-spec HRT 427 couldn't be built in such limited quanities for the $215,000 asking price, the project was eventually cancelled with deposits returned to eager buyers.

For Chooka at least, the HRT 427 will join his collection of over 20 mint-condition Monaro's dating from 1968 through to 2006.
