The Mitsubishi Eclipse IV (4G), specifically the facelifted version produced from 2009 to 2011, represented a significant evolution of the Eclipse lineage. Offered as both a coupe and a liftback, the 2.4-liter (162 hp) automatic variant occupied a middle ground within the fourth-generation Eclipse lineup, positioned between the base 2.0-liter models and the more performance-oriented turbocharged GT variants. This configuration aimed to provide a balance of affordability, reasonable performance, and everyday usability for the North American market, where the Eclipse was primarily sold.

Powertrain & Engine Architecture
The heart of this Eclipse variant was the 4G69 engine, a 2.4-liter inline-four cylinder powerplant. This engine, a member of Mitsubishi’s 4G6 family, featured a single overhead camshaft (SOHC) valvetrain and multi-port fuel injection. The 4G69 was known for its relative simplicity and durability, though it lacked the sophisticated technologies found in some competing engines. The engine produced 162 horsepower at 6000 rpm and 220 Nm (162 lb-ft) of torque at 4000 rpm. Paired with this engine was a four-speed automatic transmission with a “Sportronic” mode, allowing for some degree of manual gear selection. This transmission, while adequate, was criticized for its relatively few gears compared to newer automatic transmissions, impacting both fuel economy and responsiveness.
Driving Characteristics
The 2.4-liter automatic Eclipse offered a comfortable, if not particularly exhilarating, driving experience. Acceleration from 0-60 mph took approximately 8.9 seconds, making it slower than the turbocharged GT models. The four-speed automatic transmission, while smooth, lacked the quick shifts and wider gear ratios of more modern units. This resulted in noticeable engine drone during acceleration and a less engaging driving experience overall. The Sportronic mode offered some control, but the shifts were still relatively slow. The front-wheel-drive configuration provided predictable handling, but limited traction during hard acceleration.
Equipment & Trim Levels
The 2.4-liter automatic Eclipse typically came standard with features such as air conditioning, power windows and locks, a CD player with MP3 compatibility, and basic cloth upholstery. Higher trim levels added features like a sunroof, upgraded audio system, alloy wheels, and keyless entry. Interior materials were generally of average quality for the price point. Optional extras included leather upholstery, a navigation system, and a premium sound system.
Chassis & Braking
The Eclipse IV utilized an independent McPherson strut suspension in the front and an independent multi-link suspension in the rear. This setup provided a reasonably comfortable ride, though it wasn’t particularly sporty. Braking duties were handled by ventilated discs in the front and solid discs in the rear. Anti-lock brakes (ABS) were standard. The suspension tuning was geared towards comfort rather than aggressive handling, reflecting the target audience for this trim level.
Market Reception & Comparison
The 2.4-liter automatic Eclipse was generally viewed as a sensible and affordable option within the fourth-generation Eclipse range. Critics noted its comfortable ride and adequate performance for daily driving, but also pointed out its lack of excitement compared to the turbocharged GT models. Fuel economy was average for its class, and reliability was generally good. Compared to the more powerful GT, the 2.4L offered a lower purchase price and potentially lower maintenance costs, appealing to budget-conscious buyers. However, the 2.0-liter base models offered even greater affordability, while the GT provided a significantly more engaging driving experience.
Legacy
The 2.4-liter 4G69 engine, when paired with the four-speed automatic transmission, proved to be a relatively reliable powertrain. While not known for exceptional performance, it offered years of dependable service for many owners. Today, used examples of this Eclipse variant are relatively affordable and can be found in reasonable condition. However, potential buyers should be aware of the age-related issues common to older vehicles, such as worn suspension components and potential oil leaks. The 4G69 engine itself is generally considered robust, but regular maintenance is crucial to ensure its longevity. The Eclipse IV, in its various forms, represents a final chapter in the Eclipse’s history, a car that once defined the sport compact coupe segment.
