History

Introduced in February 1965, the Holden HD had a completely new body, which was wider and longer than that of the EH but did not look so different from its predecessor but Body styling exhibited more of the GM Opel Vauxhall range. Finally, this really had room for six seats. The wheelbase had increased by 1 " with coupe utility and panel van body styles following later of that year. The engines of the predecessor were taken over; for the larger there was a high-performance version X2 with 140 bhp (103 kW).

The Holden HD range offered the normal 4 door sedan and 5 door station wagon body styles in three trim levels with the six models. The HR Standard and HR Special got square chrome frame for the headlights and other bumpers and taillights compared to its predecessor. The HD commercial vehicle range came as a 2-door coupe utility and 2 door panel van.The distribution of weight was 49.8% to the front axle,and  50.2% at rear axle.

 The most noticeable change, however, were the new engines, all bigger and stronger than their predecessors. Three versions of the inline six-cylinder Holden Red motor were available. From 2.45 l-V6, a motor with 2,638 cc and 108 hp (79 kW) at compression 8.2: 1, or 114 hp (84 kW) at compression 9.2: 1.
