The 2009-2012 Subaru Legacy V 2.5i AWD, powered by the EJ253 engine and equipped with a six-speed manual transmission, was a significant offering in Subaru’s lineup. Built on the fifth-generation Legacy platform (BL/BP chassis), it continued Subaru’s tradition of providing standard all-wheel drive and a horizontally-opposed “boxer” engine. This configuration contributed to a low center of gravity, enhancing handling and stability. The 2.5i trim aimed to provide a balance of affordability and capability, making it a popular choice for families and individuals seeking a reliable and safe all-weather vehicle.
Powertrain & Engine Architecture
The heart of the Legacy 2.5i is the EJ253 2.5-liter naturally aspirated boxer-four engine. This engine utilizes a single overhead camshaft (SOHC) design and multi-point fuel injection. The boxer layout, with its horizontally opposed pistons, inherently reduces vibrations and contributes to a lower center of gravity. The EJ253 produced 170 horsepower at 5600 rpm and 230 Nm (169.64 lb-ft) of torque at 4000 rpm. The six-speed manual transmission offered precise gear changes and allowed drivers to fully utilize the engine’s power band. The transmission’s gear ratios were tuned for a balance of acceleration and fuel efficiency. Compared to the earlier four-speed automatic transmission offered in some Legacy models, the six-speed manual provided more driver control and improved responsiveness.
Driving Characteristics
The 2.5i with the manual transmission offered a more engaging driving experience than its automatic counterpart. While not a performance-oriented vehicle, the engine provided adequate power for everyday driving and highway cruising. The all-wheel-drive system delivered confident traction in various weather conditions, a hallmark of Subaru vehicles. The six-speed manual allowed for precise control over gear selection, enabling drivers to maintain optimal engine speed for acceleration or fuel economy. Compared to the 2.5 GT model with its turbocharged engine, the 2.5i offered less outright power, but it provided a smoother, more linear power delivery. The manual transmission also gave the driver more control than the continuously variable transmission (CVT) available on some trims.
Equipment & Trim Levels
The 2.5i trim level typically included standard features such as air conditioning, power windows and locks, a CD player with auxiliary input, and keyless entry. Higher trim levels, such as the Limited, added features like leather upholstery, a sunroof, and a premium audio system. Safety features were a priority for Subaru, and the 2.5i came standard with anti-lock brakes (ABS), electronic brake-force distribution, and multiple airbags. Optional extras included a navigation system, heated seats, and a rear-view camera.
Chassis & Braking
The Legacy V utilized a McPherson strut front suspension and a double-wishbone rear suspension. This setup provided a comfortable ride while maintaining good handling characteristics. The all-wheel-drive system employed a symmetrical design, distributing power evenly to all four wheels for optimal traction. The braking system consisted of ventilated discs at the front and solid discs at the rear. ABS was standard, enhancing braking performance and stability, particularly on slippery surfaces. The suspension tuning was geared towards comfort and everyday usability, rather than aggressive cornering.
Market Reception & Comparison
The Subaru Legacy V 2.5i was generally well-received by automotive critics. It was praised for its standard all-wheel drive, spacious interior, and comfortable ride. However, some reviewers noted that the engine could feel underpowered when fully loaded or climbing steep hills. Fuel economy was considered average for its class. Compared to the turbocharged 2.5 GT model, the 2.5i offered better fuel efficiency and lower maintenance costs, but it lacked the GT’s performance. Compared to front-wheel-drive competitors like the Honda Accord and Toyota Camry, the Legacy 2.5i’s all-wheel drive provided a significant advantage in inclement weather.
Legacy
The EJ253 engine, while generally reliable, is known to be susceptible to head gasket failures, a common issue with earlier Subaru boxer engines. Regular maintenance, including timely coolant changes, is crucial to prevent this problem. The six-speed manual transmission is considered durable and requires minimal maintenance. Today, the 2009-2012 Subaru Legacy V 2.5i remains a popular choice in the used car market, particularly in regions with harsh winters. Its combination of all-wheel drive, reliability, and affordability makes it a practical and appealing option for budget-conscious buyers seeking a safe and capable sedan. Parts availability is generally good, and the Legacy’s relatively simple mechanical design makes it accessible for DIY repairs.
