Holden HR

The Holden HR range was released in April 1966, replacing the Holden HD series which had been in production since 1965.^[2] In addition to a revised grille, the HR featured a reworked roofline and larger rear window (on the sedans), revised rear lights (on sedans and wagons) and changes to almost all exterior body panels.^[3]Other changes included revised ball joint front suspension,^[4] widened track, improved interior trim and woodgrain interior finish for the Premier models.^[3] Six months after the launch of the HR, all models were given a safety upgrade with the addition of front safety belts, windscreen washers, reversing lights, padded sun visors and a shatterproof interior rearview mirror.^[3]

The Holden HR passenger vehicle range offered four-door sedan and five-door station wagon body styles in three trim levels with the six models marketed as follows:

• Holden Standard Sedan^[5]             (HR 215)^[6]

The two versions of the inline, six-cylinder Holden Red motor were carried across from the HD series, both with increased engine capacity and a higher compression ratio of 9.2:1.^[3][6] The 114 bhp, 161 cu in (2.6 L) six was standard in all models except the Premiers.^[5][7] A 126 bhp 186 cu in (3.0 L) six was standard on Premiers and optional on all other models.^[5][7] The 145 bhp twin carburettor "X2" version of the "186" was initially available as an option on all models.^[5][7] The "X2" was replaced by the 145 bhp "186S" in June 1967 after Holden exhausted the remaining X2 intake manifolds; the new version was fitted with a single, two-barrel carburettor.^[3]

A lower compression (8.2:1) version of the 161 cu in (2.6 L) six was also available.^[6]

The 194 cu in (3.2 L) and later 230 cu in (3.8 L) Chevrolet six-cylinder engine was fitted for the South African market.^[1] This longer engine required the firewall to be scalloped out. This availability began partway through the HR's existence, with the 194 introduced for the 1967 model year.^[8] This was coupled to a fully synchronized, column-shifted, three-speed manual transmission sourced from Opel in West Germany.^[9] The Premier Automatic sold in South Africa retained the Australian engine, at least until 1969. The South African Holden Special had power disc brakes in front as standard from 1967.^[10]

A three-speed manual gearbox with column change and synchronization on the top two gears was standard on the HR, with a two-speed "Powerglide" automatic transmission available as an option.^[11] An Opel^[11] four-speed manual gearbox was offered from June 1967.^[12]

A total of 252,352 vehicles were produced up to January 1968 when the HR was replaced by the Holden HK series.^[13]
The price at release was A$2286 for the 161 cu in (2.6 L) Special Sedan manual and A$2856 for the Premier Station Sedan manual.^[6]
