The 2004 Subaru Impreza WRX Wagon represents a peak in the evolution of the original hatchback design, offering a blend of capability, efficiency, and daily usability that remains compelling even two decades later. This specific model year solidified the legacy of the "Duratec" powered WRX, moving away from the older "EJ" engine architecture that had defined the platform for years. For enthusiasts and practical buyers alike, the wagon body style provided a smarter alternative to the coupe, expanding the appeal beyond pure performance into the realm of genuine, weather-beaten utility. Understanding this model requires looking at how Subaru balanced the aggressive demands of the turbocharged boxer engine with the need for a livable family hauler.
The Heart of the Machine: Engine and Drivetrain
At the core of the 2004 model is the 2.5-liter turbocharged and intercooled flat-four engine, a significant upgrade from the non-turbo "Duratec" found in the base model. This powerplant, often referred to as the "EJ255" in this specific configuration, delivers a robust 266 horsepower and 250 lb-ft of torque, providing a thrilling yet manageable surge of power. The inclusion of the Active Torque Split (ATS) system is a defining characteristic, dynamically distributing power between the front and rear wheels based on driving conditions. This system, combined with the symmetrical all-wheel-drive layout, is the primary reason the WRX Wagon feels planted and confident in rain, snow, or on tight mountain roads.
Shifting Gears and Managing Power
Transmitting this power is the option of either a five-speed manual or a four-speed automatic transmission, both paired with a symmetrical limited-slip center differential. The manual gearbox, while not the most refined of its era, offers precise engagement and a direct connection that enthusiasts cherish. The automatic, while slower to respond, was highly praised for its smooth operation and effective use of the available power, making it a practical choice for those who wanted the performance without the constant clutch work. The chassis tuning strikes a balance between sporty responsiveness and comfort, absorbing road imperfections without sacrificing the driver's feel for the road.
Design, Utility, and the Wagon Advantage
The decision to offer the WRX powertrain in a wagon body style was a masterstroke, providing a level of versatility that sedans and coupes could not match. The interior space is generous, with rear seats that can fold flat to create a cavernous cargo area, perfect for hauling groceries, luggage, or outdoor equipment. The tall roof line ensures excellent visibility for the driver, a significant safety and convenience benefit in daily driving. The exterior design retains the aggressive stance and functional aesthetic of the WRX, with large wheels, a subtle rear spoiler, and signature blue accents available, all while maintaining a more subdued profile than its coupe counterparts.
Spacious and flexible cargo area with rear seats folded.
Superior all-weather capability thanks to standard AWD.
Engaging and driver-focused handling dynamics.
High-quality, durable interior materials for the era.
Strong aftermarket support and modification community.
Reliability, Maintenance, and the Long-Term View
Owning a 2004 Subaru Impreza WRX Wagon is an exercise in understanding the trade-offs that come with performance motoring. The turbocharged engine, while robust, requires diligent maintenance, including regular oil changes with high-quality synthetic oil and attention to the cooling system. Timing belt replacement is a critical, non-negotiable service item that must be performed at the recommended intervals to prevent catastrophic engine failure. While not without its common issues, which include potential head gasket concerns and wear on the automatic transmission, the wagon's mechanical simplicity compared to modern cars means that many problems are well understood and repairable by independent mechanics.
