The Subaru Impreza IV Sedan 2.0i, produced between 2011 and 2015, represented a significant evolution in Subaru’s compact car lineup. Part of the fourth generation (GE/GH/GR/GV) Impreza, this variant aimed to balance fuel efficiency, practicality, and Subaru’s signature symmetrical all-wheel drive system. Positioned as a mid-range offering within the Impreza sedan range, the 2.0i model served as a step up from the base 1.6L engine, offering increased performance without the higher price tag of the more powerful WRX models. It was primarily marketed towards buyers seeking a reliable, all-weather capable sedan for daily commuting and family use, particularly in regions with inclement weather.

Powertrain & Engine Architecture
The heart of the Impreza 2.0i is the FB20 2.0-liter naturally aspirated boxer engine. This engine, a hallmark of Subaru engineering, features a horizontally opposed configuration, which contributes to a lower center of gravity and improved balance. The FB20 utilizes multi-point fuel injection and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. This configuration allows for efficient combustion and a relatively broad powerband. The engine produces 150 horsepower at 6,200 rpm and 196 Nm (144.56 lb-ft) of torque at 4,200 rpm. The engine’s longitudinal mounting, coupled with Subaru’s symmetrical all-wheel drive system, provides excellent traction and handling characteristics. The 2.0i was exclusively offered with a 6-speed manual transmission during these production years, providing drivers with direct control over the engine’s power.
Driving Characteristics
The 6-speed manual transmission in the Impreza 2.0i provides a reasonably engaging driving experience. While not a performance-oriented vehicle, the engine delivers adequate power for everyday driving situations. Acceleration from 0 to 60 mph takes approximately 10 seconds, and the car has a top speed of 122.41 mph. The gear ratios are well-spaced, allowing the engine to remain within its optimal powerband during typical driving conditions. The symmetrical all-wheel drive system provides confident handling in various weather conditions, making it a particularly appealing choice for drivers in regions prone to snow or rain. Compared to the base 1.6L Impreza, the 2.0i offers noticeably improved acceleration and overall responsiveness. However, it doesn’t possess the outright performance of the turbocharged WRX models.
Equipment & Trim Levels
The Impreza 2.0i typically came standard with features such as air conditioning, power windows and locks, a basic audio system with CD player, and ABS brakes. Higher trim levels, often denoted by designations like “Premium,” added features like alloy wheels, a sunroof, upgraded audio systems, and keyless entry. Interior upholstery was typically cloth, with options for leather in higher trims. The dashboard layout was functional and straightforward, prioritizing usability over luxury. Optional extras included a navigation system, Bluetooth connectivity, and a rear-view camera.
Chassis & Braking
The Impreza 2.0i utilizes an independent McPherson strut suspension in the front and a double wishbone suspension in the rear. This setup provides a comfortable ride quality while maintaining reasonable handling characteristics. The car is equipped with ventilated disc brakes in the front and solid disc brakes in the rear. ABS (Anti-lock Braking System) is standard, enhancing braking performance and stability. The chassis is relatively lightweight, contributing to the car’s agility and fuel efficiency. Stabilizer bars are present on both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The Impreza 2.0i was generally well-received by automotive critics as a practical and reliable compact sedan. It was praised for its standard all-wheel drive, comfortable ride, and fuel efficiency. However, some critics noted that the interior design was somewhat dated and that the engine lacked the excitement of its turbocharged counterparts. Compared to other compact sedans in its class, the Impreza 2.0i offered a unique combination of features, particularly its standard all-wheel drive. Fuel economy was competitive, averaging around 29.8 US mpg in combined driving. Reliability was generally good, with the FB20 engine proving to be a durable and long-lasting powerplant.
Legacy
The FB20 engine, found in the Impreza 2.0i, has proven to be a reliable and durable powerplant. While not without its minor issues (such as potential oil consumption in some early models), it generally requires minimal maintenance and offers good longevity. Today, used Impreza 2.0i models are considered a good value for buyers seeking a dependable and all-weather capable compact sedan. The symmetrical all-wheel drive system remains a key selling point, and the car’s relatively simple mechanical design makes it relatively affordable to maintain. The Impreza 2.0i represents a solid and practical choice in the used car market, offering a blend of reliability, functionality, and Subaru’s signature driving experience.
