2005 Subaru Impreza: An Overview
The 2005 Subaru Impreza cemented its reputation as a capable and engaging compact car, offering a blend of practical everyday usability with Subaru's signature all-wheel-drive (AWD) prowess and sporty character. This generation, the second of the "GD" chassis, continued to evolve, offering improved refinement and performance across its various models.
Highlights
-
Engine Options:
- 2.5L Boxer-4 (Naturally Aspirated): Found in the base Impreza models (e.g., Outback Sport, 2.5i), this engine delivered a healthy 173 horsepower and 166 lb-ft of torque. Its signature "boxer" configuration (cylinders horizontally opposed) contributes to a lower center of gravity, enhancing handling.
- 2.0L Turbocharged Boxer-4 (WRX Models): The iconic WRX variant received a significant power upgrade for 2005, featuring a larger intercooler and revised ECU mapping. This resulted in 230 horsepower and 235 lb-ft of torque, providing exhilarating acceleration and rally-inspired performance.
- 2.5L Turbocharged Boxer-4 (WRX STI Models): The pinnacle of the Impreza range, the WRX STI, boasted a potent 300 horsepower and 300 lb-ft of torque from its turbocharged 2.5-liter engine. This engine was further enhanced with a Driver-Controlled Center Differential (DCCD) for advanced torque distribution.
-
Safety Features:
- Standard Symmetrical All-Wheel Drive (AWD): Subaru's legendary AWD system is a cornerstone of the Impreza's safety and capability. It continuously monitors road conditions and distributes power to the wheels with the most traction, significantly improving stability and control in adverse weather (rain, snow, ice) and during spirited driving.
- Front-Seat Side Airbags: Providing crucial torso protection in side-impact collisions.
- Front and Rear Crumple Zones: Designed to absorb and dissipate impact energy during a collision, protecting the occupants.
- Anti-lock Braking System (ABS): Helps prevent wheel lock-up during hard braking, allowing the driver to maintain steering control.
- Electronic Brake-force Distribution (EBD): Works with ABS to optimize braking force between the front and rear wheels based on load conditions.
-
Trim Summary:
- Impreza 2.5i: The entry-level sedan, offering a comfortable ride and standard AWD for everyday commuting.
- Outback Sport: Essentially a lifted, more ruggedized version of the Impreza wagon, featuring increased ground clearance and body cladding, making it a practical choice for light off-road excursions or navigating rougher terrain.
- WRX: The enthusiast's darling, delivering a significant performance boost with its turbocharged engine and sport-tuned suspension. It offered a thrilling driving experience without the extreme performance (and cost) of the STI.
- WRX STI: The ultimate expression of the Impreza's performance potential. This model was distinguished by its aggressive styling (hood scoop, rear wing), more powerful engine, advanced AWD system (DCCD), and upgraded braking and suspension components.
-
Other Notable Aspects:
- Boxer Engine Sound: The distinctive burble and rumble of Subaru's boxer engines is a characteristic loved by many enthusiasts.
- Practicality: Available in both sedan and wagon body styles, offering versatility for different needs. The wagon, in particular, provided ample cargo space.
- Rally Heritage: The Impreza's lineage is deeply intertwined with World Rally Championship (WRC) success, and this connection fueled the desirability of the WRX and STI models.
What to Expect
Owning a 2005 Subaru Impreza, particularly the WRX and STI variants, is often an engaging and rewarding experience for those who appreciate its performance and AWD capabilities.
- Driving Experience: Expect a car that feels planted and confident, especially in inclement weather. The steering is generally responsive, and the suspension, particularly on the WRX and STI, provides a good balance between sporty handling and acceptable ride comfort for daily driving. The boxer engine's low center of gravity contributes to excellent cornering stability.
- Maintenance: Like many performance-oriented vehicles, the WRX and STI models can require more attentive maintenance. This includes regular oil changes (with quality oil), timing belt replacements (typically around 100,000 miles), and checks of turbocharger components. The naturally aspirated models are generally more straightforward and less demanding in terms of specialized maintenance. Regular inspections of the AWD system and suspension components are also advisable.
- Insurance: Due to their sporty nature and the higher performance of the WRX and STI models, insurance premiums can be higher than for comparable non-performance compact cars, especially for younger drivers. It's always recommended to get insurance quotes before purchasing.
Potential Considerations
While the 2005 Impreza offers many positives, potential buyers should be aware of a few common considerations:
- Head Gasket Issues: A known issue with earlier Subaru models, including some 2005 examples, is the potential for head gasket leaks. While Subaru improved head gasket design over the years, it's still a point to inspect. Signs can include coolant loss, white smoke from the exhaust, or milky oil.
- Turbocharger Wear (WRX/STI): The turbochargers in the WRX and STI models are put under significant stress. Regular oil changes and allowing the turbo to cool down after spirited driving can prolong its life, but wear and tear are inevitable with age. Turbo failures can be costly to repair.
- Rust: As with any vehicle of this age, rust can be a concern, particularly in areas with harsh winters and road salt. Inspecting the undercarriage, wheel wells, and body panels for corrosion is crucial.
- Interior Noise: While improved over previous generations, some road and engine noise can still penetrate the cabin, especially on the WRX and STI models, which often feature a stiffer suspension.
- Age of Components: Being a 2005 model, various components such as rubber bushings, hoses, and electrical connectors may be nearing the end of their service life and could require replacement.
Overall Summary
The 2005 Subaru Impreza stands as a compelling choice for those seeking a compact car that balances everyday practicality with engaging driving dynamics and the added security of all-wheel drive. The standard Impreza models offer a comfortable and capable commuter, while the WRX and WRX STI variants deliver potent turbocharged performance for the enthusiast. While some potential buyers might need to be mindful of age-related wear and tear, a well-maintained 2005 Impreza remains a rewarding vehicle to own and drive, offering a unique blend of capability and character.
