The Holden Dealer Team (HDT) was Holden's semi-official racing team from 1969 until 1986, primarily contesting Australian Touring Car events but also rallying, rallycross and Sports Sedan races during the 1970s. From 1980 the Holden Dealer Team, by then under the ownership of Peter Brock, diversified into producing modified road-going Commodores and other Holden cars for selected dealers via HDT Special Vehicles.

Rallycross is a form of sprint style automobile racing, held on a closed mixed-surface racing circuit, with modified production or specially built road cars, similar to the World Rally Cars. It is mainly popular in the Nordic countries, the Netherlands, Belgium, France and Great Britain. An inexpensive, entry level type of rallycross is the Swedish folkrace or its Norwegian counterpart, the so-called bilcross. The folkrace is most popular in Finland where it was founded back in the late 1960s. In Europe, rallycross can also refer to racing 1:8 scale off-road radio-controlled buggies.
