Overview and Summary
The 2006 Mitsubishi Eclipse GT coupe is a midgeneration refresh of the third-generation Eclipse, offering a blend of sporty styling, available all-season capability, and a more refined interior while retaining the platform strengths that defined the model. As a performance-oriented variant within the Eclipse lineup, the GT combines a turbocharged inline-four, a firmer suspension, and distinctive exterior treatments with everyday usability. This profile outlines key specifications, standard equipment, common updates across model years, and typical ownership considerations to help readers evaluate the 2006 Eclipse GT as a used vehicle.
Model Generation and Positioning
The 2006 Eclipse belongs to the third generation of the Eclipse (1999–2006 model years) and arrived mid-cycle with updates to appearance, features, and mechanical refinements. Within the range, the GT sits above the base and ES trims and below the high-performance Ralliart, positioning it as a performance-focused yet practical daily driver. The underlying platform shares components with the Lancer and Galant, contributing to efficient packaging, a low center of gravity, and balanced weight distribution.
Trim Hierarchy and Market Position
Within the 2006 Eclipse lineup, trim levels typically included Base, ES, GT, and Ralliart, each adding stages of performance, comfort, and technology. The GT targets buyers who want turbocharged responsiveness, firm handling, and aggressive styling without moving up to the top-tier Ralliart. Compared with contemporaneous sport coupes, the Eclipse GT offers a more compact profile, available AWD, and distinctive Mitsubishi styling cues.
Engine and Performance
Power for the 2006 Eclipse GT comes from a 2.4-liter turbocharged inline-four (4G69) mated to a four-speed automatic or a five-speed manual, with all-wheel drive available. This powertrain produces around 160–175 hp and approximately 170 lb-ft of torque, delivering responsive acceleration and confident highway merging. Road test data typically places 0–60 mph times in the low to mid-10-second range for the automatic, with the manual variant often a half-second or so quicker. The suspension is tuned for firm, controlled handling, providing responsive turn-in and minimal body roll for the class.
Drivetrain and Drivability
The optional S-AWC (Super All-Wheel Control) system, available on the GT, apportions torque between front and rear wheels and can independently send power to the left and right rear wheels through an electronically controlled clutch pack. This setup enhances traction in various conditions and contributes to nimble, confidence-inspiring cornering. Drivers can choose different modes—auto, snow, and locked—tailoring feel and response to road surfaces. The manual transmission appeals to enthusiasts who prefer direct control, while the automatic offers smoother daily driving.
Interior, Comfort, and Usability
Inside, the 2006 Eclipse GT combines sporty aesthetics with practical usability. Bucket seats with bolstered sides and available leather inserts provide lateral support during spirited driving while remaining comfortable on longer trips. The center console layout groups climate controls, a six-speaker audio system, and available navigation within easy reach. Rear seating is best suited for occasional use, with upright seating angles and limited headroom due to the fastback profile. Trunk capacity measures roughly 13 cubic feet, aided by a low, accessible opening and foldable rear seats for expanded cargo needs.
Standard Features and Options
Standard equipment on the GT typically includes power windows and locks, air conditioning, a tilt-telescoping steering wheel, cruise control, a four-speaker audio system, and keyless entry. Options often expand this with leather-wrapped steering wheel and shift knob, power moonroof, premium audio with subwoofer, and advanced safety features such as traction control, stability control, and side-curtain airbags. Availability of specific options can vary by model year and market, so verifying build sheets for individual vehicles is recommended.
Fuel Economy and Efficiency
Fuel efficiency for the 2006 Eclipse GT reflects its sport-oriented tuning and optional AWD. EPA estimates for the automatic, all-wheel-drive version are approximately 21 mpg city and 29 mpg highway, with the manual AWD typically rated at 22 city and 30 highway. Front-wheel-drive variants, when equipped, may show slightly higher numbers. These figures position the Eclipse GT in the midrange of its class for combined efficiency, better than some high-performance rivals but lower than compact sedans optimized for economy.
Safety and Driver-Assistance Features
For its model year, the 2006 Eclipse GT includes stability and traction control, dual front airbags, side-curtain airbags, and anti-lock brakes. Some trims add tire-pressure monitoring and available advanced cruise control with following distance control. While these systems meet or exceed contemporary safety norms, they are less comprehensive than modern suites that include pedestrian detection, automatic emergency braking, and blind-spot monitoring. Owners should confirm which safety packages their specific vehicle includes, as offerings vary by market and model year.
Common Issues and Maintenance
Owners of the 2006 Eclipse GT typically report a reliable powertrain when maintenance intervals are followed, though some concerns have emerged over time. Potential issues include wear in the turbocharger wastegate actuator, carbon buildup on the throttle body and intake valves, and premature failure of certain vacuum lines and hoses. The automatic transmission can show signs of harsh shifting or torque converter problems if not serviced with the correct fluid and intervals. Regular oil changes with the proper viscosity, timely spark plug replacement, and inspections of the cooling system help mitigate these risks. Checking for recalls and known technical service bulletins is advisable for any used purchase.
Routine Maintenance Highlights
- Engine oil and filter: every 5,000–7,500 miles with full-synthetic oil
- Air filter: inspect and replace at least annually or as needed
- Spark plugs: typically every 30,000–60,000 miles, depending on type
- Coolant and hoses: inspect for wear and leaks every 15,000–30,000 miles
- Transmission fluid and filter: service per manufacturer recommendations
- Brake pads and rotors: inspect every 12,000–15,000 miles
Ownership Costs and Value Retention
Ownership costs for the 2006 Eclipse GT align with its class, with scheduled maintenance running similarly to other mid-size sport coupes. Parts are generally available through Mitsubishi dealers and aftermarket channels, though some interior trim pieces and specific turbo components may carry higher replacement costs. Insurance premiums tend to be moderate, reflecting the vehicle’s age, performance capabilities, and parts availability. Resale value is mixed; well-maintained examples with low mileage and service records typically retain decent value, while high-mileage vehicles face steeper depreciation. Market prices for 2006 Eclipse GT models vary by condition and location, but ranges commonly fall between moderate-to-competitive within the used sporty coupe segment.
Buying Checklist and Comparison
When considering a 2006 Eclipse GT, verify maintenance history, confirm installed options, and inspect for signs of turbocharger stress or cooling-system wear. Comparing the GT to contemporaries such as the Honda Civic Si, Mazda3 Sport, and Volkswagen GTI highlights tradeoffs in size, tuning character, and availability of AWD. The Eclipse GT offers a more relaxed rear-seat environment than some rivals, compact exterior dimensions for urban maneuvering, and a distinctive design language that stands out in certain markets.
