Overview

The 1990 Mitsubishi Eclipse is a sporty 2-door compact coupe/hatchback that launched the first-generation Eclipse (1990–1994). It was positioned as an affordable alternative to pricier sport coupes, offering sharp styling, available turbo performance, and practical hatchback utility. It’s ideal for drivers who want a lightweight, driver-focused ‘90s car that’s easy to modify and still usable as a daily driver with the right upkeep. Today it’s a popular enthusiast platform, but condition and maintenance history matter more than mileage alone.

Key Features

- First-year, first-generation Eclipse (DSM platform), available as a 3-door hatchback and 2-door coupe depending on trim/market, with a low-slung sporty profile. - Engine options typically include a 1.8L inline-4 (base models) and a 2.0L inline-4; performance trims used the 2.0L turbocharged 4G63T, a major draw for tuners and performance buyers. - Available 5-speed manual transmission for a more engaging drive; some trims offered an automatic, but manuals are often preferred for longevity and performance feel. - Independent suspension tuning aimed at agile handling for the era, plus a relatively light curb weight that helps acceleration and fuel economy. - Sport-focused cabin layout with supportive front seating and a practical hatch area that makes it more usable than many coupes from the same period.
