The 1971 Holden HQ Monaro, owned and built by Dr Don Hudson and co-driven by himself and Dr Justin Clarke, both from NSW, reached speeds of up to 259km/h at this year's Australian Dry Lakes Racers Speedweek at Lake Gairdner, South Australia.
Dr Hudson and Dr Clarke are the only drivers running an LPG-powered vehicle for land speed racing. Both drivers aimed to break 320km/h, although wet weather conditions and track changes restricted them to 259km/h.
