The Mitsubishi Diamante, produced from 1990 to 2000, was a mid-size luxury sedan that aimed to compete with established players like the Toyota Cressida and Honda Legend. The first-generation Diamante launched in 1990, boasting a sleek and modern design with a focus on comfort and refinement. It came equipped with a range of engine options, including a 2.5-liter V6 and a 3.0-liter V6, offering a balance of power and fuel efficiency. Interior amenities emphasized luxury, with features like leather seating, woodgrain accents, and a well-appointed dashboard. The Diamante's ride quality was lauded for its smooth and controlled nature, providing a comfortable experience for both driver and passengers.

Beyond its core features, the Diamante offered optional upgrades like a sunroof, power seats, and a premium sound system. It also came with advanced safety features for the time, including anti-lock brakes (ABS) and dual front airbags. Despite its ambitious positioning, the Diamante struggled to gain significant traction in the American market. Sales figures remained modest, likely due to factors like its relatively high price point and competition from established luxury brands. Despite its limited commercial success, the Diamante represented Mitsubishi's foray into the premium sedan segment, showcasing their capability to design and engineer vehicles with sophisticated features and styling. Its contributions to the brand's image and technological development further solidified Mitsubishi's position as a reputable and innovative automaker.
