The Subaru Impreza IV Hatchback 2.0i, produced between 2011 and 2015, represented a significant evolution for Subaru’s popular compact model. Part of the fourth generation (GE/GH/GR/GV chassis codes), this variant occupied a middle ground in the Impreza lineup, offering a blend of practicality, Subaru’s signature symmetrical all-wheel drive, and a continuously variable transmission (CVT), marketed as Lineartronic. It aimed to appeal to buyers seeking fuel efficiency and ease of driving without sacrificing the Impreza’s renowned all-weather capability. This model was primarily sold in markets where Subaru had a strong presence, including North America, Europe, and Australia.

Powertrain & Engine Architecture
The heart of the Impreza 2.0i Lineartronic is the FB20 2.0-liter horizontally-opposed (boxer) four-cylinder engine. This engine was a key component of Subaru’s efforts to improve fuel efficiency while maintaining the brand’s performance characteristics. The FB series engines, introduced in 2008, featured a square bore and stroke (84mm x 90mm) and a relatively high 10.5:1 compression ratio. The FB20 utilizes multi-point fuel injection and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The Lineartronic CVT, a key feature of this variant, is a chain-driven unit offering simulated gear ratios for a more natural driving experience. Unlike traditional automatic transmissions, CVTs don’t have fixed gears, instead using a belt and pulley system to provide a seamless range of ratios. This contributes to improved fuel economy and smoother acceleration.
Driving Characteristics
The 150 horsepower and 196 lb-ft of torque produced by the FB20 engine, coupled with the Lineartronic CVT, resulted in a comfortable and predictable driving experience. Acceleration from 0-60 mph took around 10.5 seconds, which was adequate for daily commuting but not particularly sporty. The CVT’s programming prioritized fuel efficiency, meaning the engine often operated at lower RPMs during cruising. While this enhanced fuel economy, it could sometimes feel sluggish when requiring quick bursts of acceleration. Compared to the six-speed manual transmission available on other Impreza models, the CVT offered a more relaxed driving experience, particularly in city traffic. The symmetrical all-wheel drive system provided excellent traction in various weather conditions, a hallmark of the Subaru brand.
Equipment & Trim Levels
The 2.0i Lineartronic 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 also a priority, with standard inclusion of anti-lock brakes (ABS), electronic brake-force distribution (EBD), and multiple airbags. Optional extras included a sunroof, upgraded audio systems with Bluetooth connectivity, and alloy wheels. Interior upholstery was typically cloth, with higher trims offering leather options. The dashboard layout was functional and straightforward, prioritizing ease of use over stylistic flair.
Chassis & Braking
The Impreza IV Hatchback utilized a MacPherson strut front suspension and a double-wishbone rear suspension, providing a comfortable ride and predictable handling. The chassis was designed to balance rigidity with weight reduction. Braking duties were handled by ventilated discs at the front and solid discs at the rear. The ABS system helped to maintain steering control during hard braking. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The Impreza 2.0i Lineartronic was generally well-received by automotive critics as a practical and fuel-efficient option in the compact hatchback segment. However, some reviewers noted that the CVT could feel less engaging than a traditional automatic or manual transmission. Compared to the more powerful 2.5-liter Impreza variants, the 2.0i offered lower performance but better fuel economy. Against competitors like the Honda Civic, Toyota Corolla, and Mazda3, the Impreza distinguished itself with its standard all-wheel drive, a feature not commonly found in this class. Reliability was generally good, although some owners reported minor issues with the CVT over the long term.
Legacy
The FB20 engine and Lineartronic CVT combination proved to be a reliable powertrain in the Impreza IV. While not known for blistering performance, the setup offered a good balance of fuel efficiency, practicality, and all-weather capability. In the used car market, these Imprezas are often sought after by buyers looking for a dependable and affordable compact car with the added security of all-wheel drive. The FB20 engine, in particular, has a reputation for longevity when properly maintained, making these Imprezas a viable option for budget-conscious buyers.
