The Subaru Legacy V 3.6R, produced between 2009 and 2012, represented the fifth generation of Subaru’s mid-size sedan. Positioned as the top-tier trim level within the Legacy V range, the 3.6R distinguished itself with a potent 3.6-liter boxer engine and standard all-wheel drive. This variant aimed to provide a blend of performance, comfort, and all-weather capability, appealing to buyers seeking a more refined and powerful alternative to the base and 2.5i models. It was primarily sold in North America, where Subaru had established a strong reputation for its symmetrical all-wheel drive system and durable vehicles.

Powertrain & Engine Architecture
The heart of the Legacy 3.6R is the EZ36D 3.6-liter horizontally-opposed (boxer) six-cylinder engine. This engine, a hallmark of Subaru engineering, features a 60-degree V-angle. The boxer configuration contributes to a lower center of gravity, enhancing handling and stability. The EZ36D utilizes multi-port fuel injection and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. This design allows for efficient combustion and a broad torque curve. The engine produces 256 horsepower at 6000 rpm and 247 lb-ft of torque at 4400 rpm. The engine is paired with a five-speed automatic transmission, specifically designed to handle the engine’s output and deliver smooth shifts. This transmission features adaptive learning, adjusting shift points based on driving style.
Driving Characteristics
The 3.6R offered a noticeably more spirited driving experience compared to the 2.5i models. The higher horsepower and torque figures translated to quicker acceleration and more confident passing maneuvers. While not a sports sedan, the 3.6R provided ample power for everyday driving and highway cruising. The automatic transmission, while generally smooth, wasn’t as responsive as the available six-speed manual. The all-wheel drive system provided excellent traction in various weather conditions, a key selling point for Subaru. The gear ratios were tuned for a balance between fuel efficiency and performance, prioritizing comfortable cruising over outright acceleration.
Equipment & Trim Levels
The 3.6R trim came standard with a comprehensive list of features. These included leather upholstery, heated front seats, a premium audio system, automatic climate control, and alloy wheels. Optional extras included a power moonroof, navigation system, and a Harman Kardon audio upgrade. The interior design was generally conservative, focusing on functionality and durability rather than flashy aesthetics. The dashboard layout was straightforward and easy to use, with logically placed controls.
Chassis & Braking
The Legacy V 3.6R utilized an independent McPherson strut front suspension and a double-wishbone rear suspension. This setup provided a comfortable ride while maintaining good handling characteristics. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering. The braking system consisted of ventilated discs on all four wheels, providing ample stopping power. Anti-lock brakes (ABS) were standard, enhancing safety and control during emergency braking situations. The steering was a rack-and-pinion system, offering precise and responsive steering feel.
Market Reception & Comparison
Critics generally praised the Legacy 3.6R for its powerful engine, standard all-wheel drive, and comfortable ride. However, some reviewers noted that the automatic transmission could feel sluggish at times and that the interior design was somewhat dated compared to competitors. Compared to the 2.5i models, the 3.6R offered a significant performance upgrade but came at a higher price point and with slightly lower fuel economy. Against rivals like the Toyota Camry and Honda Accord, the Legacy 3.6R stood out with its standard all-wheel drive, offering a unique advantage in regions with inclement weather. Fuel economy was rated at 18 mpg city and 25 mpg highway, which was typical for a V6-powered sedan of that era.
Legacy
The EZ36D engine, while generally reliable, is known to require regular maintenance, particularly regarding oil consumption. Some owners have reported issues with head gasket leaks, a common concern with Subaru boxer engines. However, with proper care and maintenance, the EZ36D can provide many years of reliable service. Today, the Legacy V 3.6R holds a modest position in the used car market. Its appeal lies in its combination of performance, all-wheel drive capability, and relative affordability. It remains a viable option for buyers seeking a durable and capable mid-size sedan, particularly in areas where all-weather traction is a priority. Parts availability is generally good, and the vehicle’s relatively simple mechanical design makes it accessible for DIY repairs.
