The Subaru Legacy VI 3.6R, produced between 2014 and 2017, represented the pinnacle of performance for the sixth generation of Subaru’s mid-size sedan. Positioned as the range-topping trim, it offered a significant step up in power and refinement compared to the more economical 2.5i models. This variant was primarily marketed in North America and select international markets, leveraging Subaru’s reputation for all-wheel drive capability and durability. The 3.6R distinguished itself with a naturally aspirated 3.6-liter boxer engine paired exclusively with a continuously variable transmission (CVT) and Subaru’s symmetrical all-wheel drive system.

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, prioritizes smoothness and a low center of gravity. The EZ36D utilizes a multi-port fuel injection system and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The boxer configuration inherently reduces vibrations, contributing to a refined driving experience. The engine produces 256 horsepower at 6000 rpm and 247 lb-ft of torque at 4000 rpm. This power is then channeled through Subaru’s Lineartronic CVT, a continuously variable transmission designed for smooth, efficient power delivery. Unlike traditional stepped automatic transmissions, the Lineartronic CVT offers an infinite number of gear ratios within its range, optimizing engine speed for either fuel economy or performance. The engine’s longitudinal mounting and the symmetrical all-wheel-drive system contribute to balanced handling.
Driving Characteristics
The 3.6R offered a noticeably more spirited driving experience than the base 2.5i models. While the CVT doesn’t provide the traditional gear shifts of an automatic transmission, it allows the engine to remain in its optimal power band. Acceleration is brisk, and the all-wheel-drive system provides excellent traction in various weather conditions. Compared to a manual transmission equipped Legacy, the CVT prioritizes smoothness and ease of use over outright performance. The CVT’s programming allows for simulated “shifts” in Sport mode, providing a more engaging driving feel. However, some drivers found the CVT’s operation to be less responsive than a traditional automatic. The weight distribution, thanks to the boxer engine, contributes to predictable handling and a stable feel, especially during cornering.
Equipment & Trim Levels
As the top-tier trim, the 3.6R came standard with a comprehensive list of features. Interior appointments included leather upholstery, heated front seats, a power-adjustable driver’s seat, and a premium audio system. Standard technology included a touchscreen infotainment system with navigation, Bluetooth connectivity, and a rearview camera. Optional extras included a moonroof, premium Harman Kardon audio, and advanced safety features like adaptive cruise control and lane departure warning. The exterior typically featured unique alloy wheel designs and chrome accents to differentiate it from lower trims.
Chassis & Braking
The Legacy 3.6R utilized a McPherson strut front suspension and a double-wishbone rear suspension, providing a comfortable ride and responsive handling. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering. Braking duties were handled by ventilated disc brakes on all four wheels, providing ample stopping power. The anti-lock braking system (ABS) was standard, enhancing safety and control during emergency braking situations. The suspension tuning was geared towards a balance between comfort and handling, making it suitable for both daily commuting and longer road trips.
Market Reception & Comparison
Critics generally praised the Legacy 3.6R for its smooth engine, comfortable ride, and standard all-wheel drive. However, the CVT transmission received mixed reviews, with some finding it less engaging than traditional automatics. Compared to the 2.5i models, the 3.6R offered a significant performance upgrade, but at a higher price point and with slightly lower fuel economy. Against competitors like the Toyota Camry and Honda Accord, the Legacy 3.6R stood out with its standard all-wheel drive and unique boxer engine configuration. Fuel economy was rated at 23.1 US mpg combined, which was typical for a V6-powered mid-size sedan of that era.
Legacy
The EZ36D engine, while robust, is known to require regular maintenance, particularly oil changes. The CVT transmission, while generally reliable, can be susceptible to issues if not properly maintained. Today, the Legacy 3.6R represents a compelling option in the used car market for buyers seeking a comfortable, capable, and well-equipped mid-size sedan with all-wheel drive. Its unique engine and transmission combination, while not universally loved, offer a distinctive driving experience. Well-maintained examples continue to provide reliable transportation, and the Legacy’s reputation for durability ensures a continued demand in the used car market.
