The Mitsubishi Sigma: A History and Evolution

The Mitsubishi Sigma, a luxury sedan, was introduced in 1980 and looked to be a contender in the growing luxury car market of Japan. Over the years, the Sigma underwent a series of evolutions and became known for its well-rounded driving experience, comfort, and style.

The First-Generation Mitsubishi Sigma (1980-1987)

The first-generation Sigma, which replaced the venerable Galant Lambda, was released in 1980. It stood out for its aerodynamic design that was both sleek and aggressive. The original Sigma was launched with a 2.0-liter inline-four engine that produced 100 horsepower and came with either a manual or automatic transmission.

In 1982, the first significant update came with the introduction of a 2.6-liter four-cylinder engine that produced 110 horsepower. The Sigma also received premium upgrades, including leather seats, power windows, and a sunroof, making it an attractive option for luxury car buyers.

In 1984, Mitsubishi launched the GSR variant, which boasted a turbocharged engine that put out 170 horsepower and a four-speed automatic transmission. It was the first turbocharged engine offered by Mitsubishi and set the stage for more high-performance versions of the Sigma down the line.

The Second-Generation Mitsubishi Sigma (1988-1996)

Mitsubishi treated the Sigma to a complete redesign in 1988 with the introduction of the second-generation model. The new Sigma embraced a more angular design and featured updated mechanics to match.

The second-generation Sigma was equipped with a 3.0-liter V6 engine that produced 165 horsepower and featured a four-speed automatic transmission. Additionally, the Sigma now had four-wheel steering, which enhanced the sedan’s handling and made it easier to maneuver tight corners.

In 1992, to add more power to the Sigma lineup, Mitsubishi released the Sigma GT. It was powered by a 3.5-liter V6 engine that produced 230 horsepower and was paired with a four-speed automatic transmission. The Sigma GT also featured revised suspension, a sport-tuned exhaust system, and 16-inch alloy wheels.

The Third-Generation Mitsubishi Sigma (1996-2007)

The third-generation of the Mitsubishi Sigma debuted in 1996 and included a wholly redesigned exterior and interior compared to previous generations. The new styling was more angular and aggressive, making the Sigma stand out in the crowded luxury sedan market.

The third-generation Sigma featured a 3.0-liter V6 engine with a five-speed manual or four-speed automatic transmission. The new model saw much-improved driving dynamics, including a stiffer and more rigid chassis, improved suspension, and greater body control.

In 2003, Mitsubishi added another option to the Sigma lineup with the introduction of the Sigma Eterna. It was a variant that broke away from the conventional sedan style and offered coupe-like lines. The Eterna was equipped with a 2.5-liter V6 engine that produced 160 horsepower, mated to a four-speed automatic transmission.

The Fourth-Generation Mitsubishi Sigma (2007-2012)

The fourth-generation Mitsubishi Sigma, which debuted in 2007, marked a shift toward a more conservative design approach. The Sigma now featured softer, rounded lines, giving it a more dignified look. However, the engine options remained unchanged from the previous generation, with a 3.0-liter V6 engine as the standard offering.

The fourth generation Sigma continued to boast excellent driving comfort and handling, and its four-wheel-drive made it a standout in slippery road conditions. The car also received visual upgrades with more refined color and material options.
