FactIn September 1981 Mitsubishi built 500 Sigma Turbos with Normalair-Garrett -- the first turbocharged production car ever built in Australia.
On 28 April 1980 Chrysler unveiled the GH Sigma in Brisbane, and on 30 April Mitsubishi Corporation and Mitsubishi Motors jointly acquired Chrysler's remaining 65 percent of Chrysler Australia; on 1 October 1980 the GH range was rebadged from Chrysler Sigma to Mitsubishi Sigma with the renaming to Mitsubishi Motors Australia. Released on 12 May, it had a considerable front and rear facelift (which had appeared in Japan and on New Zealand-assembled cars in 1979), the mechanical layout as before except for a five-speed manual for the 2.6-litre model (the automatic moved to the options list), the base model now simply "Sigma", and a GLX between GL and SE advertised as a "sports pack". A limited run of 1,016 "Peter Wherrett" GLX editions (option A05) was built, named after the Australian motoring journalist who was tasked by MMAL with improving the handling after complaining about it: 15-inch Globe "Montego" alloys with Pirelli P6 tyres, Recaro seats, a Momo steering wheel, Sonic extractors, lowered coil springs and Bilstein shocks. A limited-edition GL-based Sigma Satellite followed in about April 1981 (two-tone paint, unique hubcaps, soft-grip sports wheel, cloth upholstery, full tinted glass and laminated windscreen). The GH was discontinued in February 1982. The page gives no power figures for the GH, so none are entered; the 500-car Sigma Turbo is catalogued separately.

Owning one
We don’t estimate running costs for a car like this. What it costs depends on its condition, its specialist and how it is driven, and an average would mislead.

Photographs

This car wore three different badges inside of five years in North America — the Galant Sigma for 1986, then simply the Sigma for 1989 and 1990.

This facelifted Sigma got its own cheeky limited run late in 1984 — the GK Sigma Satellite, with a 2.6-litre engine, five-speed manual, side stripes and its own badge, aimed squarely at Christmas buyers.

The Australian-built GJ Sigma was the only Australian car exported to Europe in the 1980s — sold in the UK, sedan and wagon both, under a marque invented for the job: Lonsdale.

This Sigma Turbo was a genuine first: a limited run of 500, built with Normalair-Garrett, became the first Australian-built turbocharged production car.

Rivals
Same body, same money, other badges — tap any card to flip.

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.
