FactNew Zealand's Trentham plant kept building HQs into 1975, a year after Australia moved on, just to use up leftover parts.
The Holden HQ series is a range of automobiles produced by Holden in Australia from July 1971 to October 1974, released on 15 July 1971 to replace the HG series. It was the first ground-up redesign of the Holden line since its original release in 1948, with an all-new body, chassis and suspension, designed by Phillip Zmood, and developed into a series of successor models that finally ended production when the WB series was discontinued in 1985. The mainstream range consisted of four-door sedan and five-door station wagon models (Belmont, Kingswood and Premier, the Premier topping the range with woodgrain interior and full-length armrests and the XV8 GTS350 sedan of 1973), with the Monaro coupé range (LS and GTS), the limited-edition SS variant of the Belmont V8 sedan (253 or 308 cubic-inch V8, Aussie four-speed, 3.36:1 Salisbury differential), the One Tonner cab-chassis and coupé utility, panel van and Sandman variants; the long-wheelbase Statesman HQ was sold separately, and the car was also assembled in Wellington, New Zealand, and sold in South Africa as the Chevrolet Kommando, El Camino and El Toro (the Kommando only with the Chevrolet 4.1-litre six). Engines were the 2.83-litre (173 cu in) and 3.3-litre (202) "Red" sixes, the 4.1-litre (253) and 5.0-litre (308) Holden V8s and the imported 5.7-litre Chevrolet 350 V8, in low- and high-compression forms for the smaller engines, with 3-speed manual, Aussie 4-speed manual, 3-speed Tri-Matic automatic and Turbo-Hydramatic transmissions. HQ production totalled 485,650 vehicles at Holden's Acacia Ridge, Dandenong, Elizabeth and Pagewood plants, and HQ production in New Zealand at Trentham ran until 1975 to use up parts not needed for the following HJ series.

It briefly served as senior sibling to Marquette, a GM companion brand cancelled after just one year.
Nissan hired former BMW engineers to help develop the 510's suspension, which is why period reviewers frequently compared its handling to the BMW 1600/2002.
A Trabant 601 won its class at the 1970 Monte Carlo Rally, with a second 601 right behind it in second.
The 600 was a stopgap: the P50's body over the 601's mechanicals, and for a while its estate was built alongside the new 601 saloon.
The G80 Sport brought a 370 PS twin-turbo 3.3 V6, a mesh grille and copper-tinted chrome with copper stitching to match.
The Vigor was sold only with a five-cylinder engine, an unusual configuration Honda used to fit a longer engine transversely under a short hood.
The GS/E coupe earned the nickname "German Charger" for its long hood, short deck stance borrowed from Detroit muscle cars.
This DeVille/Fleetwood was the first production car anywhere to mount its V8 sideways, Cadillac's front-drive gamble on the new C-body.
