The Mitsubishi Eclipse first generation (1G), produced from 1989 to 1994, represented Mitsubishi’s entry into the competitive American compact coupe market. The 2.0i 16V variant, available from 1990-1992, was a significant offering within the lineup, positioned as a step up from the base 1.6L engine while remaining more accessible than the turbocharged and all-wheel-drive models. This version, typically paired with a four-speed automatic transmission, aimed to provide a balance of performance and convenience for buyers seeking a stylish and relatively affordable sports coupe. The 1G Eclipse shared its platform with the Eagle Talon and Plymouth Laser, a result of the Diamond-Star Motors joint venture with Chrysler.

Powertrain & Engine Architecture
The 2.0-liter 4G63 inline-four engine powering the Eclipse 2.0i 16V was a key component of the Diamond-Star Motors collaboration. This engine featured a double overhead camshaft (DOHC) valvetrain operating four valves per cylinder, contributing to its relatively high specific output for a naturally aspirated engine of the time. Fuel delivery was managed by a multi-point fuel injection system, enhancing efficiency and responsiveness. The 9:1 compression ratio was a compromise between performance and the fuel quality available in the US market. The engine’s block was cast iron, while the cylinder head was aluminum, a common construction for balancing durability and weight. Paired with this engine was a four-speed automatic transmission, designed for smooth operation and ease of use. This transmission wasn’t known for its sportiness, prioritizing comfort over aggressive shifting.
Driving Characteristics
The 135 horsepower and 170 Nm (125 lb-ft) of torque delivered by the 2.0-liter engine, when coupled with the four-speed automatic, resulted in a 0-60 mph time of around 9-10 seconds. While not blistering, this was adequate for the era and positioned the Eclipse as a reasonably quick coupe. The automatic transmission’s gear ratios were geared towards fuel economy and smooth cruising, rather than maximizing acceleration. Compared to the five-speed manual version, the automatic noticeably diminished the car’s responsiveness. The automatic also lacked the engine braking benefits of a manual transmission. The front-wheel-drive configuration provided predictable handling, but could exhibit torque steer under hard acceleration.
Equipment & Trim Levels
The 2.0i 16V Automatic typically came standard with features like power steering, air conditioning, and an AM/FM stereo. Interior upholstery was usually cloth, with a relatively simple dashboard layout. Optional extras included a sunroof, upgraded stereo systems (often with a cassette player), and alloy wheels. The trim level often dictated the availability of these options, with higher trims offering more standard features. The base model was fairly spartan, while the higher-spec versions offered a more comfortable and refined experience. Power windows and locks were often optional, depending on the specific package.
Chassis & Braking
The Eclipse 1G utilized an independent coil spring suspension at the front and an independent multi-link suspension at the rear, providing a comfortable ride and reasonably good handling. The front and rear brakes were both disc brakes, a relatively advanced feature for a car in this price range. However, the braking system wasn’t particularly powerful, and fade could be an issue under sustained hard use. Stabilizer bars were included at both the front and rear, helping to reduce body roll during cornering. The suspension tuning was geared towards a balance between comfort and handling, leaning more towards the former.
Market Reception & Comparison
The Eclipse 2.0i 16V Automatic was generally well-received as an affordable and stylish coupe. Critics praised its attractive design and comfortable interior, but noted that the automatic transmission detracted from the driving experience compared to the manual. Compared to the turbocharged Eclipse GSX and GS-T models, the 2.0i offered significantly less performance, but at a lower price point. It also offered better fuel economy than the turbocharged variants. Against competitors like the Honda Civic Coupe and Toyota Celica, the Eclipse offered a more aggressive styling and a slightly more sporty feel, but often lacked the refinement and reliability of its Japanese rivals.
Legacy
The 1G Mitsubishi Eclipse, particularly the 2.0i 16V variant, has developed a cult following among enthusiasts. The 4G63 engine is renowned for its durability and potential for modification. While the automatic transmission isn’t highly sought after by performance enthusiasts, it provides a comfortable and reliable option for those seeking a classic coupe. Today, well-maintained examples of the 2.0i 16V are becoming increasingly rare and collectible. The powertrain, while not exceptionally powerful by modern standards, is generally considered reliable if properly maintained. Common issues include oil leaks and wear on suspension components, typical for a vehicle of this age. The Eclipse 1G remains a popular choice for restoration projects and a nostalgic reminder of the 1990s sports coupe era.
