The Mitsubishi Diamante was first introduced to the public at the Tokyo Motor Show in 1989, and went on sale in Japan in May 1990. It became the second generation Magna, replacing the widened 1983 Galant Sigma-based Magna. The luxury version of the Magna, Mitsubishi Verada was the Australian equivalent of the Diamante.

There have been rumors that the Diamante was either not intended for a Japanese launch, or it might have been planned as a low-volume model. The reason for this argument is that until 1989, the width of vehicles was a vital indication of taxation class. The Diamante, being wider than the 1700 mm break, would have suffered a large tax penalty against most of its rivals, which were designed to be just under limit. At the time, Mitsubishi’s image was also considered less than ideal for the marketing of a luxury car—its most expensive offering that the time, the Debonair, was largely seen as a company car project for Mitsubishi conglomerate executives.

However, the tax situation had changed in 1989, and the Diamante became the surprise hit of 1990. Amidst Japan’s bubble economy, many private car owners sought an executive car in a market that had very few new offerings that year.

The Japanese market Diamante was a four-door hardtop with no window sashes. Five months after the Diamante’s launch, Mitsubishi also introduced the Sigma, which was different from the Diamante with its slightly taller roofline, six-windows as opposed to four-window glasshouse, window sashes, and front/rear treatment.

In Japan, the Diamante was available with three V6 engines (2.0, 2.5 and 3.0 Liter) of the 6G7 family; all wheel drive was available on most models. Perhaps contrary to its overseas image, Mitsubishi at the time fully emphasized the use of electronic gadgets in its cars, and the Diamante is notable for a long list of such features. This generation won the Japan Car of the Year award in 1990. The Diamante was first sold in 1992 in the United States, replacing the Sigma, which was based on previous generation Mitsubishi Galants.

In Australia, the Sigma was manufactured locally as the Mitsubishi Verada, with a cheaper mainstream version known as the Magna. The Magna/Verada station wagon was designed locally in Australia, and was exported to Japan and the United States as the Diamante wagon, and to Europe as the Sigma wagon.
