The Subaru Legacy IV 2.0R, produced from 2005 to 2006, represented a significant iteration of Subaru’s mid-size sedan. Positioned as a step up from the base model Legacy, the 2.0R variant combined a 2.0-liter naturally aspirated boxer engine with a four-speed automatic transmission and Subaru’s symmetrical all-wheel drive system. This configuration aimed to deliver a balance of performance and practicality for the North American market, where the Legacy competed with vehicles like the Honda Accord and Toyota Camry. The fourth-generation Legacy (BL/BP chassis) introduced a more refined interior and improved ride quality compared to its predecessor, solidifying Subaru’s reputation for building durable and capable vehicles.

Powertrain & Engine Architecture
The heart of the 2.0R was the EJ204 engine, a 1994cc (121.68 cubic inches) 2.0-liter horizontally opposed (boxer) four-cylinder. This engine design, a Subaru hallmark, offered a low center of gravity, contributing to the car’s balanced handling. The EJ204 featured multi-port fuel injection and a single overhead camshaft (SOHC) per cylinder bank, operating with four valves per cylinder. The engine produced 165 horsepower at 6800 rpm and 187 Nm (137.92 lb-ft) of torque at 3200 rpm. Paired with this engine was a four-speed automatic transmission, designed for smooth operation and ease of use. While not offering the sportiness of a manual transmission, the automatic was well-suited for everyday driving and provided a comfortable experience. The powertrain’s longitudinal engine layout and symmetrical all-wheel drive system were key components of Subaru’s engineering philosophy, providing enhanced traction and stability in various weather conditions.
Driving Characteristics
The 2.0R Automatic delivered adequate, though not exhilarating, performance. Acceleration from 0-60 mph took around 10.8 seconds, and the car had a top speed of 124.9 mph. The four-speed automatic transmission, while smooth, lacked the responsiveness of more modern transmissions with a greater number of gears. Gear ratios were tuned for fuel efficiency and comfortable cruising rather than aggressive acceleration. Compared to the five-speed manual version of the 2.0R, the automatic felt noticeably slower. The all-wheel drive system provided confident handling in slippery conditions, but the car’s weight (1455 kg / 3207.73 lbs) contributed to a somewhat ponderous feel in corners. The boxer engine’s unique vibration characteristics were present, but generally well-damped, providing a distinctive driving experience.
Equipment & Trim Levels
The 2.0R trim level typically included features such as air conditioning, power windows and locks, a CD player, and alloy wheels. Higher trim levels, such as the Limited, added features like leather upholstery, a sunroof, and upgraded audio systems. Standard safety equipment included ABS brakes and front airbags. Optional extras available for the 2.0R included a premium sound system, heated seats, and a navigation system. The interior design was functional and relatively spacious, with comfortable seating for five passengers. The dashboard layout was straightforward and easy to use, with logically placed controls.
Chassis & Braking
The Legacy IV utilized a MacPherson strut front suspension and a coil spring rear suspension. The suspension was tuned for a comfortable ride, prioritizing smoothness over sporty handling. The 2.0R featured ventilated disc brakes at the front and solid disc brakes at the rear. ABS (Anti-lock Braking System) was standard, providing enhanced braking performance and stability. The steering was rack and pinion with hydraulic power assistance, offering a reasonable level of feedback and precision. The car’s relatively modest weight and all-wheel drive system contributed to stable and predictable braking performance.
Market Reception & Comparison
The Subaru Legacy IV 2.0R Automatic was generally well-received by automotive critics as a practical and reliable mid-size sedan. However, the four-speed automatic transmission was often criticized for its lack of responsiveness compared to competitors offering five or six-speed automatics. Fuel economy was average for the class, with combined fuel consumption of 8.5 l/100 km (27.7 US mpg). Compared to the more powerful 2.5R variant, the 2.0R offered a lower price point but sacrificed some performance. The 2.0R appealed to buyers seeking a safe, comfortable, and all-weather capable sedan without the need for high-performance acceleration.
Legacy
The EJ204 engine, while generally reliable, is known to be susceptible to head gasket issues, a common problem with earlier Subaru boxer engines. Regular maintenance, including timely coolant changes, is crucial to prevent this issue. The four-speed automatic transmission is also relatively durable, but may exhibit signs of wear and tear at high mileage. Today, the 2005-2006 Subaru Legacy IV 2.0R Automatic can be found on the used car market at affordable prices. Its all-wheel drive system and reputation for reliability continue to make it an attractive option for buyers seeking a practical and dependable vehicle, particularly in regions with inclement weather. However, potential buyers should be aware of the potential for head gasket issues and factor in the cost of preventative maintenance.
