Welcome to the all new Holden Heaven
  Holden HQ 1971


HQ Realeased in 1971
The HQ was introduced with all the fan-fare it deserved, it was to turn out to be the most popular Holden ever. There would hardly be a household in Australasia that has not had a HQ parked in the drive at some stage. There were new bits everywhere on this model which was the first complete body change since the HK was released in 1968. The rear leaf springs were replaced with coils which was probably it's only major fault, as anyone would have seen, when you have a load in the HQ the back-end looked like it was dragging on the ground. The reason for this was as the release date approached there had not been enough research spent on this area to avoid sagging. The Holden engineers were very happy with this new car as this time they felt they had achieved almost everything that was set for them back in the late 60's when they were told to develope a new style.  Check out the feature on the HQ Decision.  Availabe in a huge array of styles, options, engines, transmissions, wheels, interior and even the Monaro was now available in 4 and 2 door. The Top end of the range was the stretched Statesman De Ville which was 26cm longer than the HQ sedan thanks to the lengthened boot. The Sandman was released late in 1974 but was not sold in many numbers as Holden waited for the new HJ before marketing this model. The HQ became the biggest selling Holden model ever and has not been beaten to this day. With the advent of HQ racing it is still a popular choice of car for racing or customizing into a Street Machine with almost every GM engine dropped into the massive engine bay.  Another popular motor are diesels which the Nissan LD28 would be the most used transplant option.

 Pics
The Kingswwod dash layout as seen by thousands of people who have driven these models over the years and still drive them.


This Kingswood is in good hands with the wide-eyed Brock at the wheel and co-driver Fred Gocentas looking rather bemused with the way Peter was taking this water crossing!  This was taken during the International Don Capasco Rally in March of 1974. Something that must be mentioned, in an interview with brock many years later he recalled, ''I really enjoyed the Don Capasco, though. I drove really hard and we won quite a few stages. I was rapt when one of the reports came out saying, '...and Brock set the forests alight in the Kingswood''.  ''I remember asking Fred if I was going fast enough and he said I was doing alright. But I started going faster and faster and Fred just sat there as cool as could be. Years later, he told someone it had been the fastest he'd ever been in a rally car. I just thought, Thank God for that, because I thought it was awfully fast!"


In the Dulux Rally which ran between Brisbane and Melbourne in 1974.
