[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: The HR commercial vehicle range was offered in two-door coupe utility and two-door panel van variants, marketed as follows: 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.

[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.

[8] This was coupled to a fully synchronized, column-shifted, three-speed manual transmission sourced from Opel in West Germany.

[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.

[12] A total of 252,352 vehicles were produced up to January 1968 when the HR was replaced by the Holden HK series.
