Full 1990 Mitsubishi Sigma Review
What's New for 1990
Mitsubishi's answer to the Accord and Camry is the updated Sigma. For 1990 it receives a 3.0-liter V6 engine as standard equipment. Antilock brakes are available as a standalone option on the Sigma for the first time. Delayed accessory power allows the driver to close windows and the sunroof for up to 30 seconds after the ignition is turned off.
