The Holden Commodore (VC) HDT

In late 1979, Holden pulled out of touring car racing after two years of domination by the LX Torana A9X SS hatchback. In 1980, this led to Peter Brock buying the Holden Dealer Team (HDT), though without Holden funding was needed to continue racing and development. This led to the creation of a modified VC Commodore, tuned and styled under the direction of Peter Brock who established HDT Special Vehicles, not only to produce enhanced versions of the Commodore but as a way of funding the race team. The result was a luxury-performance version of the VC Commodore, to be sold through select Holden dealers throughout Australia as the HDT Commodore. The HDT Commodore was powered by an HDT tuned 5.0-litre V8 engine, producing 160 kW (210 hp) at 4500 rpm. The HDT Commodore was a limited edition vehicle, with exactly 500 production models produced. These only sold with a choice of three colours (Palais White, Firethorn Red or Tuxedo Black) to pay homage to Marlboro, HDT’s main sponsor at the time.
