The Mitsubishi Sigma Diamante, launched in 1991, was a mid-size sedan that marked a significant step forward for the Japanese automaker in the North American market. It represented a departure from the traditionally smaller and less-powerful Mitsubishi offerings, offering a refined and spacious interior, advanced technology, and a level of luxury that challenged established players in the segment. The Diamante was available in a variety of trim levels, ranging from the well-equipped base model to the luxurious LS, each showcasing Mitsubishi's commitment to delivering a premium driving experience. Powering the Diamante was a range of robust 4-cylinder and V6 engines, mated to either a 4-speed automatic or a 5-speed manual transmission, offering a balance of performance and efficiency.

The Sigma Diamante also introduced a range of innovative features that were groundbreaking for its time. Notably, the Diamante LS boasted a sophisticated Electronic Controlled Suspension (ECS) system, which automatically adjusted the suspension settings based on driving conditions and driver input, providing a comfortable ride and enhanced handling. Its aerodynamic styling contributed to a smooth and stable driving experience, while its spacious interior provided ample room for passengers and cargo. The combination of design, performance, and technology solidified the Sigma Diamante's reputation as a compelling alternative to established luxury sedans of the era. Its success paved the way for Mitsubishi's subsequent ventures into the premium car market, laying the foundation for more sophisticated and luxurious offerings to come.
