Diamante/Sigma

1990

Diamante/Sigma

The market for Japanese luxury cars took off after a revision to the tax system in April 1989 when commodity tax was abolished and changes made to the vehicle tax, as well as after revisions to the voluntary insurance system for private cars. Accurately pinpointing these market trends the Diamante 4-door hardtop which came to market in May 1990 is notable for having created the 2.5 L segment. With its wide body taking it out of the mid-sized car bracket Diamante's form gave it an imposing road presence and a subtle profundity that would not have been possible in the mid-sized car category. Its sizable living space stemming from the wide body featured wrap around cockpit styling and seats designed to support the occupant's center of gravity. All models in the range were powered by V6 engines with electrically controlled variable inlet valve system. 4-wheel drive models were fitted with Mitsubishi Motors' Active Four system: fulltime 4-wheel drive, 4-wheel steering, 4-wheel ABS and 4-wheel independent suspension. 2-wheel drive models were fitted with the Traction control system as well as the Active Two system: active electronically controlled suspension, 4-wheel steering, 4-wheel ABS and 4-wheel independent suspension. These systems helped deliver confidence-inspiring driving dynamics. Diamante also showcased a number of cutting-edge technologies including the MICS Mitsubishi Integrated Communications System, a world-first, that automatically adjusted seat, steering wheel and other positions to match the driver and his preferences. In November that year, a new Sigma 4-door sedan, derived from the Diamante but giving greater priority to interior comfort, was launched. Three years after the Galant, Diamante and Sigma won the Car of the Year Japan award for 1990-1991.
