Introduced in January 1968, the HK range progressively replaced the Holden HR series which had been in production since 1966.
HK models were both larger and heavier than their predecessors and the range would ultimately include thirteen different models against the eight of the HR range. The Holden HK was marketed under Belmont, Kingswood, Premier, Brougham and Monaro model names.
The HK series was initially offered in three trim levels, each available in four door sedan and five door station wagon body styles. Sedans and wagons were marketed as Sedans and Station Sedans respectively.
Belmont Station Sedan
Kingswood Station Sedan
Premier Station Sedan
The Belmont and Kingswood model names were new for the HK series, replacing the Standard and Special names which had been used by Holden since 1953. The Premier nameplate was retained for the top of the line model which now featured four headlights and a unique roofline to differentiate it further from its lesser siblings. 161 cubic inch (2.6 litre) and 186 cubic inch (3.0 litre) in line six cylinder engines were carried over from the HR series, however a 307 cubic inch (5.0 litre) Chevrolet V8 was now offered as an option on all models, this being the first time that any Holden had been available with a V8 engine.
In March 1968 the HK range was expanded with the release of two coupe utilities and a panel van variant replacing the existing HR series commercial models.
Belmont Panel Van
Prior to the introduction of the HK models, Holden’s commercial vehicles had been marketed simply as the Holden Utility and the Holden Panel Van.
July 1968 saw the release of an additional HK sedan and three coupe models:
Monaro GTS 327
The Brougham featured a greater level of luxury than the Premier, which had been the top of the range Holden since the introduction of the nameplate in 1962. The Brougham also featured an overall length 200 millimetres (8 in) greater than the other HK sedans, although this extra length was added to the body only, while the wheelbase remained unchanged at 111 inches. It was equipped with the 307 cubic inch V8 engine as standard. The Monaro models were 2 door coupes, the first such vehicles to be offered by Holden and the Monaro GTS 327 featured a 327 cu in (5.4 L) Chevrolet V8 engine which was not available in any other Holden model.
