The Mitsubishi Sigma Diamante is a full-size luxury sedan that was produced by Mitsubishi Motors from 1990 to 2005. The name "Diamante" is Italian for "diamond," chosen to evoke a sense of luxury and refinement. The first generation (1990-1995) of the Diamante was introduced in 1989 (as the Sigma in Japan) and was a departure from Mitsubishi's previous conservative designs. It featured a more aerodynamic and modern styling, with a spacious and luxurious interior that aimed to compete with European luxury sedans. The Sigma Diamante was available with a range of powerful engines, including a 2.5-liter V6 and a 3.0-liter V6, paired with either a 4-speed automatic or a 5-speed manual transmission. Notably, the Diamante was one of the first Japanese cars to offer advanced features like ABS, traction control, and an optional driver's airbag.

The Diamante's success was not only due to its stylish appearance and advanced features, but also its reputation for reliability and durability. It garnered critical acclaim for its smooth ride, comfortable cabin, and responsive handling. The Diamante also featured a well-equipped interior with standard amenities such as power windows, locks, and mirrors, as well as luxurious options like leather upholstery, heated seats, and a premium sound system. Although sales were modest compared to its Japanese rivals, the Diamante still managed to establish itself as a strong contender in the luxury sedan segment. The second-generation (1995-2005) Diamante continued to refine the formula, incorporating newer engines, improved technology, and a refreshed design. Ultimately, the Sigma Diamante served as a flagship model for Mitsubishi, showcasing its engineering prowess and its commitment to building cars that could stand toe-to-toe with the best in the world.
