March of 1965 saw Australia’s conservative car buyers shaking their heads as the most radical design in Holden history appeared on our roads.
The HD model took proven mechanicals and enclosed them in a USA-inspired shape, with more shoulder room and boot space than the record-setting EH, but controversial aspects to its styling as well.
Up front were aggressively curved mudguards with edges extending well past the headlights. Further back, the tail-lights could be seen from side-on and doors curved outwards to make fitting three adults across each seat an easier task
Under the bonnet there were changes too, including a switch from three-speed automatic to the two-speed Powerglide and availability of a twin carburetor X2 engine with 18.5kW more power than the single-carburetor ‘179’. For those wanting a basic version of the new Holden, the entry-level 149 cubic inch engine remained available.
Holden’s very successful Premier continued, as a sedan or station wagon with the stock 179 motor or X2. Most Premiers were automatic but manual cars do exist. Anyone who tells you that the HD was the worst car in Holden history is lying.
Initial response to the new release was frantic, with the new model selling faster than the EH and buyers needing to wait weeks for special orders.
Despite sales that topped 178,000 cars, Holden still replaced its HD range after 14 months with the restyled and less controversial HR model.
It was launched in April 1966 with two slightly enlarged Red Six engines – a 2.6-litre 161 cubic inch and 3048cc 186.
Transmission choices were three-speed manual or two-speed Powerglide, followed in 1967 by a four-speed all-synchromesh manual.
Premiers in HR form remained the best-equipped Holdens, with revamped seats and extra woodgrain (plastic) trim.
Power steering, front disc brakes, the X2 or later single carburetor 186S engines were optional, as was a four-speed manual.
From late 1966, anticipating new rules being implemented the following year, front seat belts, reversing lights, improved door locks and padded sun visors were fitted to all HR Holdens.
Premiers with the high-performance engines and four-speed gearbox have been seen at auction a few times since 2023 and a couple of cars have topped $80,000.
Powerglide Premiers in excellent condition will sell at half the price of four-speed cars with the Special and the now scarce Standard in good condition at around $20,000. An excellent Powerglide Special can reach $35,000 with HDs of similar quality around 20 per cent less expensive.
