MITSUBISHI Sigma 1991-1996 Photos, engines & full specs

Mitsubishi gathered all the Japanese technology and stuffed it into one vehicle, and tried to compete with the much more acclaimed BMW 5-Series on the European market.

The result was named Sigma, and it was, basically, an over-engineered Mitsubishi Diamante. But the carmaker didn't add unnecessary features to the vehicle. It tried to add things that, in 1991, looked more suitable for the Enterprise star-ship than for an executive sedan.

But Mitsubishi forgot to pay a big chunk of money to the design department, and the car's shape was under its engineering abilities. At the front, it featured dual-headlights and a vertical slot in the middle that sported Mitsubishi's three-diamonds badge. The third window behind the rear doors enhanced the interior lightness for the back-seat passengers.

Inside, the car sported a leather-clad interior with comfortable seats and tons of features. Its Clarion sound system featured a 6-CD changer in the trunk and a radio-cassette player in the dash. Moreover, Mitsubishi offered a few extra features such as cruise control and innovative safety features. The carmaker installed a traction-control and electronic stability control for the Sigma. Moreover, it added a variable ground clearance button that allowed the driver to raise or lower the car, depending on the road conditions.

Under the hood, the 3.0-liter V-6 was carried over from the 3000 GT sports-car and provided over 200 hp. It was paired to either an electronically controlled four-speed automatic transmission or to a five-speed manual. The only two technical features that were not available for the Sigma were the all-wheel-drive and the all-wheel-steering systems, which Mitsubishi installed on other models.
