The Subaru Impreza IV Sedan (facelift 2015) 2.0i with the Lineartronic continuously variable transmission (CVT) represents a significant iteration of Subaru’s popular compact car. Produced from 2015 to 2016, this variant occupied a middle ground within the Impreza lineup, offering a balance between affordability, fuel efficiency, and Subaru’s signature symmetrical all-wheel drive. It was part of the fourth-generation Impreza (GE/GH/GR/GV), which saw a substantial refresh in 2015, including revised styling and improved interior materials. This model aimed to appeal to buyers seeking a practical, reliable, and all-weather capable sedan.

Powertrain & Engine Architecture
The 2.0i Lineartronic Impreza utilizes Subaru’s FB20 2.0-liter naturally aspirated boxer engine. This engine is characterized by its horizontally opposed pistons, which contribute to a lower center of gravity and reduced vibration. The FB20 features multi-point fuel injection and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The Lineartronic CVT, a key component of this variant, is a continuously variable transmission designed to optimize fuel efficiency and provide smooth acceleration. Unlike traditional automatic transmissions with fixed gear ratios, the Lineartronic uses a belt and pulley system to offer an infinite number of ratios within its operating range. This allows the engine to operate at its most efficient RPM regardless of vehicle speed. The FB20 engine produces 150 horsepower at 6,200 rpm and 196 Nm (144.56 lb-ft) of torque at 4,200 rpm.
Driving Characteristics
The 2.0i Lineartronic Impreza delivers a comfortable and predictable driving experience. The CVT, while prioritizing efficiency, can feel less responsive than a traditional automatic or manual transmission. Acceleration from 0-60 mph takes approximately 10.5 seconds, which is slower than Impreza models equipped with a manual transmission or the more powerful 2.5-liter engine. The CVT’s programming often holds the engine at a consistent RPM during acceleration, which can result in a “rubber band” feel. However, the symmetrical all-wheel drive system provides excellent traction and stability in various weather conditions. The Lineartronic transmission is programmed with simulated “shift points” to mimic the feel of a conventional automatic, which some drivers find preferable.
Equipment & Trim Levels
The 2.0i Lineartronic trim typically included standard features such as air conditioning, power windows and locks, a rearview camera, a 6.2-inch touchscreen infotainment system with Bluetooth connectivity, and Subaru’s EyeSight driver-assist technology (depending on package). Interior upholstery was typically cloth, with options for upgraded materials available. Available options included a sunroof, heated front seats, and a premium audio system. The facelifted 2015 model benefited from improved interior materials and a more refined dashboard layout compared to earlier Impreza generations.
Chassis & Braking
The Impreza IV Sedan features a MacPherson strut front suspension and a double-wishbone rear suspension, providing a comfortable ride and predictable handling. The 2.0i Lineartronic model utilizes ventilated front disc brakes and solid rear disc brakes. Anti-lock braking system (ABS) is standard. The suspension tuning is geared towards comfort rather than sporty handling, making it well-suited for everyday driving. Stabilizer bars are present at both the front and rear to reduce body roll during cornering.
Market Reception & Comparison
The 2.0i Lineartronic Impreza was generally well-received by automotive critics as a practical and fuel-efficient option in the compact sedan segment. However, the CVT transmission was a common point of criticism, with some reviewers noting its lack of responsiveness. Compared to the 2.5-liter Impreza, the 2.0i offered lower running costs but less overall performance. Against competitors like the Honda Civic and Toyota Corolla, the Impreza stood out with its standard all-wheel drive, a feature not commonly found in this class. Fuel economy figures of around 34.6 US mpg combined were competitive for the time.
Legacy
The FB20 engine and Lineartronic CVT combination proved to be relatively reliable in the Impreza IV. While CVTs generally require more diligent maintenance than traditional automatics (including regular fluid changes), the Subaru Lineartronic has a reputation for durability when properly maintained. Used examples of the 2015-2016 Impreza 2.0i Lineartronic are readily available on the used car market, often at affordable prices. These models continue to appeal to buyers seeking a dependable, all-weather capable, and fuel-efficient compact sedan.
