The Subaru Legacy VI (facelift, introduced in 2017) 3.6R, equipped with a 256 horsepower engine and a continuously variable transmission (CVT), represented the top-tier performance offering within the sixth generation Legacy lineup. Produced from 2017 through 2019, this variant aimed to provide a blend of spaciousness, all-weather capability, and refined power for the North American market, where the Legacy traditionally competed with mid-size sedans like the Toyota Camry and Honda Accord. The facelift brought updated styling and enhanced features to the already well-regarded Legacy platform.

Powertrain & Engine Architecture
The heart of the 3.6R Legacy was the EZ36 3.6-liter horizontally-opposed (boxer) six-cylinder engine. This engine was a hallmark of Subaru’s engineering, known for its smooth operation and inherent balance. The EZ36 featured a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder, and utilized multi-port fuel injection. The boxer configuration, with its pistons moving horizontally, contributed to a lower center of gravity, enhancing handling characteristics. The engine produced 256 horsepower at 6000 rpm and 247 lb-ft of torque at 4400 rpm. Paired exclusively with Subaru’s Lineartronic CVT, the 3.6R eschewed traditional gear ratios for a continuously variable system designed to optimize fuel efficiency and provide smooth acceleration. The Lineartronic CVT allowed the engine to operate within its optimal power band more consistently.
Driving Characteristics
The 3.6R’s driving experience was markedly different from the lower-trim Legacy models. While the CVT aimed for efficiency, the 3.6-liter engine provided ample power for confident passing and merging. The CVT, while smooth, lacked the direct feel of a traditional automatic transmission, and some drivers found its simulated “shift points” to be less engaging. The all-wheel-drive system, standard on all Legacy models, provided excellent traction in various weather conditions. Compared to the 2.5-liter four-cylinder engine offered in other Legacy trims, the 3.6R offered significantly more power and a more refined driving experience, albeit at the cost of slightly reduced fuel economy.
Equipment & Trim Levels
The 3.6R typically represented the highest trim level available on the Legacy. Standard features included leather upholstery, heated front seats, a premium audio system, automatic climate control, and Subaru’s EyeSight driver-assist technology, which incorporated adaptive cruise control, lane departure warning, and automatic emergency braking. Optional extras often included a power moonroof, navigation system, and upgraded interior trim. The interior design focused on comfort and functionality, with a user-friendly infotainment system and ample space for passengers and cargo.
Chassis & Braking
The Legacy VI utilized a McPherson strut front suspension and a double-wishbone rear suspension, providing a comfortable ride and predictable handling. The 3.6R models typically featured larger diameter wheels and tires (225/50R18) compared to lower trims. Braking duties were handled by ventilated disc brakes on all four wheels, providing ample stopping power. The standard all-wheel-drive system employed a symmetrical design, distributing power to all four wheels for optimal traction and stability. Anti-lock brakes (ABS) were standard equipment.
Market Reception & Comparison
Critics generally praised the Legacy 3.6R for its spacious interior, comfortable ride, and standard all-wheel drive. The 3.6-liter engine was lauded for its smooth power delivery, but the CVT transmission received mixed reviews. Some reviewers found it to be a good match for the engine’s characteristics, while others preferred the more engaging feel of a traditional automatic. 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. The 3.6R competed directly with other V6-powered mid-size sedans, such as the Toyota Camry XLE V6 and the Honda Accord V6.
Legacy
The EZ36 engine, while reliable, is known to require regular maintenance, including oil changes and coolant flushes. The Lineartronic CVT, while generally durable, can be susceptible to issues if not properly maintained. Today, the 2017-2019 Legacy 3.6R models hold reasonable value in the used car market, appealing to buyers seeking a spacious, comfortable, and all-weather capable sedan with a powerful engine. The combination of Subaru’s renowned reliability and the 3.6R’s performance makes it a desirable option for those seeking a well-rounded mid-size vehicle.
