The Subaru Legacy IV (facelift, produced from 2006 to 2007) 2.0R, equipped with a 165 horsepower engine and all-wheel drive, represented a mid-cycle refresh of the fourth-generation Legacy. Introduced as part of the BL/BP series, this variant aimed to balance performance with practicality, appealing to buyers seeking a capable and comfortable family sedan. The facelift brought subtle styling changes and refinements to the existing platform, solidifying the Legacy’s position as a key competitor in the mid-size segment, particularly for those prioritizing all-weather capability. This specific configuration, with its naturally aspirated 2.0-liter boxer engine, was positioned as a step up from the base models, offering more power without the added cost and complexity of the turbocharged options.

Powertrain & Engine Architecture
The heart of the 2006-2007 Subaru Legacy 2.0R was the EJ204 engine, a 1994cc (121.68 cubic inches) naturally aspirated 2.0-liter boxer-four. Subaru’s horizontally opposed “boxer” configuration, where pistons move horizontally rather than vertically, provides inherent balance, reducing vibrations and contributing to a smoother driving experience. The EJ204 featured a single overhead camshaft (SOHC) design per cylinder bank, operating four valves per cylinder. Fuel delivery was handled by a multi-point fuel injection system. The engine produced 165 horsepower at 6800 rpm and 187 Nm (137.92 lb-ft) of torque at 3200 rpm. This engine was paired with a five-speed manual transmission as standard. The all-wheel-drive system was symmetrical, utilizing a viscous limited-slip center differential to distribute power between the front and rear axles.
Driving Characteristics
The 2.0R offered a noticeable step up in performance compared to the base 2.5i models, but it wasn’t a sports car. Acceleration from 0-60 mph took around 9 seconds, and the car had a top speed of 133 mph. The boxer engine provided a unique engine note and a relatively low center of gravity, enhancing handling. The all-wheel-drive system provided excellent traction in various weather conditions, a hallmark of Subaru vehicles. The five-speed manual transmission offered precise shifts, but the gear ratios were tuned for fuel efficiency and everyday drivability rather than outright performance. Compared to the turbocharged Legacy GT, the 2.0R felt less powerful, but it offered a more linear power delivery and better fuel economy.
Equipment & Trim Levels
The 2.0R trim typically included standard features such as air conditioning, power windows and locks, a CD player with auxiliary input, and keyless entry. Higher trim levels, often denoted with an “Limited” designation, added features like leather upholstery, a sunroof, heated front seats, and upgraded audio systems. Alloy wheels were standard on the 2.0R, typically 17-inch in diameter. Optional extras included a navigation system and premium sound systems.
Chassis & Braking
The Legacy IV utilized a MacPherson strut front suspension and a double-wishbone rear suspension. The suspension was tuned for a comfortable ride, prioritizing smoothness over sporty handling. The 2.0R models were equipped with ventilated disc brakes at the front and solid disc brakes at the rear. Anti-lock brakes (ABS) were standard. The steering was a rack-and-pinion system with hydraulic power assistance, providing a responsive and predictable feel.
Market Reception & Comparison
The 2006-2007 Subaru Legacy 2.0R was generally well-received by automotive critics. It was praised for its standard all-wheel drive, comfortable ride, and spacious interior. However, some reviewers noted that the engine lacked the punch of the turbocharged models and that the interior materials weren’t as upscale as some competitors. Fuel economy was considered average for its class. Compared to rivals like the Honda Accord and Toyota Camry, the Legacy offered a unique driving experience thanks to its boxer engine and all-wheel-drive system. The 2.0R offered a compelling alternative for buyers who prioritized all-weather capability and a comfortable ride over outright performance.
Legacy
The EJ204 engine, while generally reliable, is known to be susceptible to head gasket failures, a common issue with early 2000s Subaru engines. Regular maintenance, including timely coolant changes, is crucial to prevent this issue. The Legacy IV, as a whole, has proven to be a durable and long-lasting vehicle. Today, well-maintained examples of the 2.0R can still be found on the used car market, offering a relatively affordable and capable all-wheel-drive sedan. Its reputation for reliability and practicality continues to make it a popular choice among budget-conscious buyers seeking a dependable vehicle.
