Chronology
Predecessor Holden HG
Successor Holden HJ

The Holden HQ series is a range of automobiles that was produced by General Motors-Holden’s in Australia from 1971 to 1974. The HQ was released on 15 July 1971, replacing the Holden HG series.[1] It was the first ground up redesign of the Holden line since its original release in 1948,[2] and included an all new body, chassis, and suspension.[1] The HQ was later developed into a series of successor models, finally ending production after the WB series was discontinued in 1984.

Model range[edit]

The mainstream passenger car range consisted of 4-door sedan and 5-door station wagon models in three trim levels.[1]

The long wheelbase luxury model, "Statesman by GMH" consisted of one body style [4-door sedan] and was available in two trim levels.

  • Statesman
  • Statesman Deville

A Holden SS Sedan was released in August 1972.[2] Although marketed as a separate model[3] in reality it was a Belmont V8 Sedan fitted with the XV2 option package.[4]

The Monaro range initially consisted only of 2-door coupes.[5]

  • Holden Monaro
  • Holden Monaro V8
  • Holden Monaro GTS
  • Holden Monaro GTS 350
  • Holden Monaro LS
  • Holden Monaro LS V8

Two 4-door sedan variants of the Monaro GTS were released in March 1973[2] and similarly to the SS the new sports sedans were a special vehicle package optioned on a lesser model, in this case on a V8 Kingswood sedan. Option XV4 was the HQ GTS sedan. Option XW8 was the HQ GTS350 sedan.

The commercial vehicle range included coupe utility, panel van and cab chassis truck models.

  • Holden Belmont Utility
  • Holden Kingswood Utility
  • Holden Belmont Panel Van
  • Holden One Tonner

The One Tonner, which was new for the HQ series, was a cab chassis truck.[2] A Sandman option, which was offered on Utility and Panel Van models from January 1974,[6] included various "sports" items from the Monaro GTS.[4]

Engines[edit]

The two inline six cylinder engines from the HG range were carried over to the HQ, but were enlarged[2] to 173 cu in (2.8 L) and 202 cu in (3.3 L).[7] The 253 cu in (4.1 L), 308 cu in (5.0 L) and 350 cu in (5.7 L) V8s were also carried over.[7]

Production[edit]

Production of the HQ range totalled 485.650 vehicles[6] prior to its replacement by the Holden HJ series in October 1974.[8]

South Africa[edit]

For the South African market, the Holden HQ sedan was marketed as the Chevrolet Kommando, the HQ utility as the Chevrolet El Camino and the HQ One Tonner as the Chevrolet El Toro.[9]

Motorsport[edit]

The "Group 3H" Holden HQ of Sarah Mitchell

From the late 1980s, the Holden HQ was used in Australia as the basis of a one-make motor racing category with an emphasis on cost. The category began in Tasmania but very quickly expanded to every state to become the entry-level motor racing category nation-wide. The cars are built to comply with CAMS Group 3H Technical Regulations.[10]

The HQ motor racing category also had an effect on spare parts in wrecking yards around Australia, with parts and body panels becoming scarce as many of the teams would 'raid' the yards for cheap spares. This led to a shortage of spares for the HQ model for anyone who owned a road-going version.

Statesman HQ[edit]

Statesman HQ de Ville

The Statesman HQ range of long wheelbase luxury sedans, based on the Holden HQ series,[11] was also released in July 1971.[12] The Statesman models replaced the Holden Brougham from the HG range [12] however they were marketed as Statesmans rather than as Holdens.[13]
Available in two trim levels, the entry car was called the "Statesman" and the premium car was the "Statesman Deville".
