The HX arrived in July 1976 as the Australian automotive
industry concentrated on meeting new anti-pollution requirements.
There was no Monaro coupe in the new HX line-up, but the
name was emblazoned on a single, extroverted GTS four
door.
Its bright colours, large GTS decals, colour-keyed mirror
and bumpers, integrated body-coloured spoiler options
and optional bonnet black-out made it the most distinctive
of all four door Monaros.
A substantial, long distance grand tourer, it retained
the longevity and built-in toughness of the HQ series
while adding greater comfort and extra appointments.
These included a new multi-function column stalk that
replaced the floor-mounted dipswitch, controlling headlight
high/low beam as well as windscreen wipers and washers.
