The Mitsubishi Diamante is an automobile that was manufactured by Mitsubishi Motors from 1990 to 2005.
The first series was a hardtop introduced to the public at the Tokyo Motor Show in 1989. It went on sale in Japan exclusively in May 1990 and won that year's Japan Car of the Year award. It was created by splicing an extra 6.6 cm (2.6 in) right down the middle of the Mitsubishi Galant, which itself had won the Japan Car of the Year award in 1987. The Diamante's platform was also used for the sporty Mitsubishi 3000GT.
The name Diamante was derived from the Spanish, Portuguese, and Italian word for "diamond" and was adopted also as homage to the Mitsubishi badge which is composed of three diamonds. In Japan, this vehicle was sold at a specific retail chain called Car Plaza.
