2008-2011 Subaru Impreza III Sedan 2.0R (150 Hp) AWD Automatic

The Subaru Impreza III Sedan 2.0R, produced between 2008 and 2011, represented a significant evolution in Subaru’s popular compact car lineup. Positioned as a mid-range offering within the third-generation Impreza (GE/GH/GR/GV chassis codes), the 2.0R variant combined a naturally aspirated 2.0-liter boxer engine with a four-speed automatic transmission and Subaru’s renowned symmetrical all-wheel drive system. This configuration aimed to provide a balance of performance, practicality, and all-weather capability for the North American market, where the Impreza competed with vehicles like the Honda Civic, Toyota Corolla, and Mazda3.

INTRODUCTION

The 2008-2011 Subaru Impreza III Sedan 2.0R Automatic was a key component of Subaru’s strategy to broaden the Impreza’s appeal. Built on the versatile 1HX0/A3 platform (shared with other Subaru models and, in some iterations, with Toyota), the Impreza aimed to deliver a compelling package of safety, reliability, and all-weather performance. The 2.0R trim, when paired with the four-speed automatic, represented a comfortable and convenient option for buyers prioritizing ease of use over outright performance. It sat in the middle of the Impreza lineup, offering more power and features than the base 2.5i models, but falling short of the more performance-oriented WRX and STI variants.

Powertrain & Engine Architecture

At the heart of the 2.0R was the EJ20 2.0-liter horizontally opposed (boxer) four-cylinder engine. This engine was a hallmark of Subaru engineering, known for its smooth operation and low center of gravity, contributing to the car’s balanced handling. The EJ20 featured a single overhead camshaft (SOHC) design and multi-point fuel injection. The engine produced 150 horsepower at 6,400 rpm and 196 Nm (144.56 lb-ft) of torque at 3,200 rpm. The four-speed automatic transmission, while providing convenience, was a somewhat dated design by the late 2000s. It featured conventional hydraulic control and lacked the efficiency and responsiveness of more modern transmissions with more gears. The transmission was specifically tuned to work with the symmetrical all-wheel-drive system, distributing power to all four wheels for enhanced traction.

Driving Characteristics

The Impreza 2.0R Automatic offered a comfortable and predictable driving experience. Acceleration from 0-60 mph took around 11 seconds, which was adequate for everyday driving but noticeably slower than the manual transmission versions or the turbocharged WRX. The automatic transmission’s gear ratios were optimized for fuel economy and smooth cruising rather than aggressive acceleration. The all-wheel-drive system provided excellent grip in various weather conditions, making it a particularly appealing choice for drivers in regions with snow or rain. However, the automatic transmission could sometimes feel hesitant during quick overtaking maneuvers, requiring a deliberate kickdown to access the engine’s power. The steering was light and precise, contributing to a confident feel on the road.

Equipment & Trim Levels

The 2.0R trim level included a number of standard features designed to enhance comfort and convenience. These typically included air conditioning, power windows and locks, keyless entry, a CD player with auxiliary input, and alloy wheels. Higher-spec 2.0R models could be equipped with optional features such as a sunroof, upgraded audio system, and leather upholstery. Interior materials were generally of good quality for the price point, with a focus on durability and practicality. The dashboard layout was functional and straightforward, with easy-to-read gauges and intuitive controls.

Chassis & Braking

The Impreza III Sedan utilized a McPherson strut front suspension and a multi-link rear suspension. This setup provided a good balance of ride comfort and handling precision. The 2.0R models typically featured ventilated front disc brakes and solid rear disc brakes. Anti-lock braking system (ABS) was standard, enhancing safety by preventing wheel lockup during hard braking. The suspension was tuned to provide a comfortable ride without sacrificing too much handling capability. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.

Market Reception & Comparison

The Impreza 2.0R Automatic received generally positive reviews from automotive critics. It was praised for its all-wheel-drive system, comfortable ride, and reputation for reliability. However, the four-speed automatic transmission was often criticized for its lack of responsiveness and fuel efficiency compared to newer transmissions. Compared to the base 2.5i models, the 2.0R offered a noticeable performance boost. Compared to the WRX, it lacked the turbocharged power and sporty handling, but it was more affordable and fuel-efficient. Fuel economy was rated at around 28 mpg combined, which was competitive for its class but not exceptional.

Legacy

The Subaru Impreza III Sedan 2.0R Automatic has proven to be a relatively reliable vehicle in the used car market. The EJ20 engine, while not without its potential issues (such as head gasket concerns common to some Subaru engines), is generally durable when properly maintained. The four-speed automatic transmission is known to be robust, but regular fluid changes are essential to ensure its longevity. Today, these Imprezas represent an affordable and practical option for buyers seeking a reliable all-wheel-drive sedan. Their relatively simple mechanical design makes them easier and less expensive to maintain than more complex modern vehicles. While not a performance icon like the WRX or STI, the 2.0R Automatic remains a capable and dependable choice for everyday transportation.
