The Subaru Forester II 2.5i Automatic, produced between 2005 and 2008, represented a significant evolution of Subaru’s popular compact SUV. Positioned as a mid-range offering within the second-generation Forester (designated chassis code SF5), this variant combined a 2.5-liter naturally aspirated boxer engine with a four-speed automatic transmission, targeting buyers seeking a blend of practicality, all-wheel-drive capability, and relative ease of use. It served as a key model in the North American market, where Subaru had established a strong reputation for reliability and all-weather performance. This model year bridged the gap between the first and third generation Forester, offering improvements in refinement and interior space over its predecessor.

Powertrain & Engine Architecture
The heart of the 2.5i Automatic Forester is the EJ253 engine, a 2.5-liter horizontally-opposed (boxer) four-cylinder. This engine design, a Subaru hallmark, contributes to a lower center of gravity, enhancing stability. The EJ253 utilizes a single overhead camshaft (SOHC) design for each cylinder bank, operating 16 valves in total. Fuel delivery is managed by a multi-point fuel injection system, providing precise fuel metering for optimal combustion. The engine’s 173 horsepower and 168.9 lb-ft of torque are respectable for its displacement, but it’s the torque curve that defines its usability. The four-speed automatic transmission, while not as sophisticated as modern continuously variable transmissions (CVTs), was chosen for its reliability and smooth operation. It features typical torque converter lock-up for improved fuel efficiency at cruising speeds. The transmission’s gear ratios are tuned for everyday driving, prioritizing comfort over outright performance.
Driving Characteristics
The 2.5i Automatic Forester delivers a comfortable and predictable driving experience. Acceleration is adequate for merging onto highways and passing slower traffic, but it’s not particularly brisk. The automatic transmission shifts smoothly, though it can sometimes feel hesitant when downshifting for quicker acceleration. Compared to the five-speed manual version of the same engine, the automatic sacrifices some responsiveness. The manual transmission allows for more driver control and slightly improved fuel economy. The all-wheel-drive system provides excellent traction in various weather conditions, making the Forester a capable vehicle for those living in areas with snow or rain. The steering is light and precise, contributing to easy maneuverability.
Equipment & Trim Levels
The 2.5i Automatic trim typically included standard features such as air conditioning, power windows and locks, a CD player, and alloy wheels. Safety features like anti-lock brakes (ABS) were also standard. Optional extras included a sunroof, premium audio system, and leather upholstery. Interior materials were generally durable and functional, though not particularly luxurious. The dashboard layout is straightforward and user-friendly, with clearly labeled controls. The rear seats offer ample legroom for passengers, and the cargo area is spacious and versatile, thanks to the folding rear seats.
Chassis & Braking
The Forester II utilizes a MacPherson strut front suspension and a double-wishbone rear suspension, providing a comfortable ride and good handling characteristics. The suspension is tuned for a balance between comfort and control, absorbing bumps and irregularities in the road surface effectively. Braking duties are handled by ventilated discs at the front and solid discs at the rear. ABS is standard, enhancing braking performance and stability in emergency situations. The chassis is robust and well-built, contributing to the Forester’s overall durability.
Market Reception & Comparison
The Subaru Forester II 2.5i Automatic was generally well-received by automotive critics. It was praised for its practicality, all-wheel-drive capability, and comfortable ride. However, some critics noted that the engine could feel underpowered, especially when fully loaded. Compared to other compact SUVs of the time, such as the Honda CR-V and Toyota RAV4, the Forester offered a more rugged and adventurous character. Fuel economy was average for its class, typically around 20-24 mpg combined. Reliability was generally good, though some owners reported minor issues with the automatic transmission over time.
Legacy
The Subaru Forester II 2.5i Automatic remains a popular choice in the used car market today. Its reputation for reliability, combined with its all-wheel-drive capability, makes it a desirable vehicle for those seeking a practical and dependable SUV. The EJ253 engine is known for its longevity, provided it has been properly maintained. While the four-speed automatic transmission is not as efficient as more modern transmissions, it is generally reliable and relatively inexpensive to repair. The Forester II 2.5i Automatic represents a sweet spot in the Forester lineage, offering a good balance of features, performance, and affordability.
