The Holden Torana is a mid-sized car that was manufactured by Holden from 1967 to 1980. The name apparently comes from a word meaning "to fly" in an unconfirmed Aboriginal Australian language. ^{[citation needed]} The original HB series Torana was released in 1967 and was a four-cylinder compact vehicle closely based on the British Vauxhall Viva HB series of 1966–1970.

Whilst the 1969–1973 (LC and LJ series) cars included more popular, longer-wheelbase six-cylinder versions, and with the 1974–1977 (LH and LX series) cars adding eight-cylinder versions to the mix, a range of four-cylinder versions continued for the entire production life of the Torana (with later four-cylinder versions being marketed as the Holden Sunbird from November 1976).

In South Korea, the LJ Torana was produced locally as the Chevrolet 1700 (시보레 1700, 1972–1976) and Saehan Camina (새한 카미나, 1976–1978).

Changing tack in Australian motor sport, Holden released the LC Torana GTR XU-1 in 1970, with performance-enhanced drivetrain and handling. From this time through to the release of the Holden Commodore, the Torana remained Holden's most successful sports/performance vehicle, with many victories garnered in rallying and circuit racing.

The introduction of the VB Commodore in 1978 was preceded by the arrival of the updated UC Torana/Sunbird twins, but with no sports versions or V8 engine options. The Torana was subsequently discontinued in 1979, followed by the four-cylinder Sunbird in 1980.

Introduced in May 1967 to replace the HA series Vauxhall Viva in the Australian market, the first Torana model was a mildly facelifted HB series Vauxhall Viva. It featured a two-door body, 12-inch (305-mm) wheels, and a 56-bhp 1.2-litre four-cylinder engine mated to a four-speed gearbox. A Borg-Warner Model 35 three-speed automatic transmission was optional. Drum brakes were fitted front and rear, with power-assisted front disc brakes optional. In terms of styling, the only points of visual difference between Viva and Torana were in the grille and headlamps, the rear tail panel (no registration plate recess), the deletion of the Viva's dashboard air vents, the wheel trims, and the badging—otherwise it was very much a straightforward exercise in badge engineering. Holden's HB Torana sedan was retailed in three model specifications: Torana, Torana S, and Torana SL ... these models effectively mirrored the concurrent larger HR Holden sedans with their three-tiered specification of Standard, Special, and Premier.

A 'sports' option package was released in October 1967, called the 'Brabham' Torana, named in honour of the well-respected Australian race-car driver, Sir Jack Brabham, who at the time was the reigning F1 World Champion and Australian of the Year for 1966. The Brabham Torana's engine featured twin CD Zenith-Stromberg carburettors fitted with individual sports air cleaners. Together with a low-restriction exhaust system, power was boosted to 79 bhp (59 kW; 80 PS). The Brabham option (available only with manual transmission on Torana S or Torana SL) also included wider wheel rims and red-wall tyres, power-assisted front disc brakes, black body accents, and subtle 'Brabham' identification badges attached to the leading edges of the front fenders and to the rear boot lid.

In early 1968, a "Series 70" engine option—equivalent to the '90' option for the British Vauxhall Viva—was added. This engine had a higher compression ratio and higher-lift camshaft (adapted from the Brabham option engine) and a single CD Zenith-Stromberg carburettor, which boosted output to 69 bhp (51 kW; 70 PS). Power-assisted front disc brakes were standardised with this engine, whilst availability of the automatic transmission option shifted exclusively to the "Series 70" engine option (no longer available with the standard 56 bhp (42 kW; 57 PS) engine).
