Holden launched the new HQ series in 1971. At this time, the company was producing all of its passenger cars in Australia, and every model was of Australian design; however, by the end of the decade, Holden was producing cars based on overseas designs. The HQ was thoroughly re-engineered, featuring a perimeter frame and semimonocoque (unibody) construction. Other firsts included an all-coil suspension and an extended wheelbase for station wagons, while the utilities and panel vans retained the traditional coil/leaf suspension configuration. The series included the new prestige Statesman brand, which also had a longer wheelbase, replacing the Brougham. The Statesman remains noteworthy because it was not marketed as a "Holden", but rather a "Statesman".
