The Subaru Legacy V (facelift, 2012-2014) 2.5i, equipped with a 2.5-liter boxer engine producing 173 horsepower and paired with a Lineartronic continuously variable transmission (CVT), represented a significant iteration of Subaru’s mid-size sedan. Introduced as part of the fifth-generation Legacy (BP/BR chassis), the 2012 facelift brought revised styling, enhanced safety features, and refinements to the powertrain. This particular variant occupied a central position within the Legacy lineup, offering a balance of performance, fuel efficiency, and standard features aimed at a broad customer base in North America and other key markets. It was positioned above the base 2.5i models with manual transmissions and below the more performance-oriented trims, if offered in specific regions.

Powertrain & Engine Architecture
The heart of the 2012-2014 Legacy 2.5i was the FB25 2.5-liter horizontally-opposed (boxer) four-cylinder engine. This engine was a key component of Subaru’s strategy to improve fuel efficiency without sacrificing performance. The FB series engines, replacing the older EJ series, featured a square bore and stroke (99.5mm x 79mm) and a relatively high 10:1 compression ratio. The FB25 utilized multi-point fuel injection and a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder. The boxer configuration, with its horizontally opposed pistons, inherently provides a lower center of gravity, contributing to improved handling. Paired with the FB25 was Subaru’s Lineartronic CVT, a chain-driven continuously variable transmission. This CVT was designed to provide smooth, seamless acceleration and optimize fuel economy by keeping the engine operating in its most efficient range. The Lineartronic CVT featured simulated “shift points” to mimic the feel of a traditional automatic transmission, addressing a common complaint about early CVTs.
Driving Characteristics
The 2.5i with the CVT offered a comfortable and predictable driving experience. While not a performance-oriented trim, the 173 horsepower and 168.9 lb-ft of torque provided adequate acceleration for everyday driving situations. The CVT’s programming prioritized fuel efficiency, resulting in a somewhat less responsive feel compared to the manual transmission variants. However, the CVT allowed the engine to remain in its optimal power band, providing consistent and usable power. The all-wheel-drive system, a hallmark of Subaru vehicles, provided excellent traction in various weather conditions. Compared to the higher-output 2.5GT models (if available in certain markets), the 2.5i felt noticeably less powerful, but it offered significantly better fuel economy. The CVT also differed in feel from the six-speed manual transmission, offering smoother acceleration but less driver engagement.
Equipment & Trim Levels
The 2.5i trim typically included standard features such as air conditioning, power windows and locks, a basic audio system with auxiliary input, and keyless entry. Safety features were a strong point, with standard inclusion of anti-lock brakes (ABS), electronic brake-force distribution, and a suite of airbags. Higher trim levels within the 2.5i range, or optional packages, could add features like a premium audio system, leather upholstery, a sunroof, and advanced safety technologies such as Subaru’s EyeSight driver-assist system. Interior upholstery was typically cloth, with higher trims offering leather options. Dashboard configurations were generally straightforward and functional, prioritizing ease of use.
Chassis & Braking
The Legacy 2.5i utilized an independent McPherson strut suspension in the front and a double-wishbone suspension in the rear. This suspension setup provided a comfortable ride quality while maintaining reasonable handling characteristics. The 2.5i typically featured ventilated disc brakes in the front and solid disc brakes in the rear. The braking system was assisted by ABS and electronic brake-force distribution to enhance safety and control. Stabilizer bars were included both front and rear to reduce body roll during cornering. The suspension tuning was geared towards comfort and everyday usability, rather than aggressive performance.
Market Reception & Comparison
The 2012-2014 Subaru Legacy 2.5i CVT was generally well-received by automotive critics. It was praised for its standard all-wheel drive, comfortable ride, and good fuel economy. However, some reviewers noted that the CVT could feel somewhat sluggish and lacked the engagement of a traditional automatic transmission. Compared to competitors like the Toyota Camry and Honda Accord, the Legacy offered a unique combination of standard features and all-wheel-drive capability. Fuel economy was competitive within its class, and reliability ratings were generally positive. The 2.5i offered a more affordable entry point into the Legacy lineup compared to the higher-trim models, making it an attractive option for budget-conscious buyers.
Legacy
The FB25 engine and Lineartronic CVT proved to be relatively reliable powertrains. While some early CVTs experienced issues, Subaru addressed these concerns with updated software and hardware revisions. Today, well-maintained 2012-2014 Legacy 2.5i models can be found in the used car market at affordable prices. The FB25 engine is known for its longevity, and the CVT, while requiring regular fluid changes, can provide years of trouble-free service. The Legacy’s reputation for safety and all-weather capability continues to make it a popular choice among used car buyers seeking a practical and dependable mid-size sedan.
