The Subaru Impreza IV Sedan 1.6i AWD Lineartronic, produced between 2011 and 2015, represented an entry point into the fourth generation (GE/GH/GR/GV) of Subaru’s popular compact car. Positioned within the broader Impreza lineup – which also included 2.0-liter naturally aspirated and turbocharged variants – the 1.6i offered a more fuel-efficient and affordable option, primarily aimed at buyers prioritizing practicality and Subaru’s renowned symmetrical all-wheel drive system. This model was largely sold in markets outside of North America, where the Impreza range was often configured differently.

Powertrain & Engine Architecture
The heart of the Impreza 1.6i Lineartronic is the FB16 1.6-liter horizontally-opposed (Boxer) four-cylinder engine. This engine, part of Subaru’s FB series, was designed to improve fuel efficiency and reduce emissions compared to its predecessors. The FB16 utilizes multi-point fuel injection and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The Boxer configuration, with its horizontally opposed pistons, contributes to a lower center of gravity, enhancing handling characteristics. Paired with this engine is Subaru’s Lineartronic continuously variable transmission (CVT). This CVT, unlike traditional stepped automatic transmissions, provides a seamless and theoretically infinite number of gear ratios, optimizing engine speed for fuel efficiency or performance. The Lineartronic featured simulated “shift points” to mimic a conventional automatic for drivers accustomed to that feel.
Driving Characteristics
The 114 horsepower output and the CVT pairing resulted in a driving experience focused on smoothness and fuel economy rather than outright performance. Acceleration from 0-60 mph took around 12 seconds, making it noticeably slower than Impreza models equipped with the 2.0-liter engine. The CVT’s programming prioritized efficiency, meaning the engine often operated at lower RPMs during cruising, contributing to quieter operation. However, aggressive acceleration required the CVT to “downshift” (simulate lower gears), which could result in a noticeable drone. The symmetrical all-wheel drive system provided excellent traction in various weather conditions, a hallmark of the Subaru brand. The Lineartronic CVT, while efficient, didn’t offer the same level of responsiveness as a traditional automatic or manual transmission.
Equipment & Trim Levels
The 1.6i Lineartronic trim typically included standard features such as air conditioning, power windows and locks, a basic audio system with CD player, and alloy wheels. Safety features included ABS brakes, electronic brakeforce distribution, and multiple airbags. Optional extras often included a sunroof, upgraded audio system with Bluetooth connectivity, and fog lights. Interior upholstery was typically cloth, with a relatively simple dashboard layout. The trim level aimed for a balance between affordability and essential comfort features.
Chassis & Braking
The Impreza IV Sedan utilized a McPherson strut front suspension and a double-wishbone rear suspension. This setup provided a comfortable ride quality, although it wasn’t particularly sporty. Braking duties were handled by ventilated discs at the front and solid discs at the rear. The braking system was adequate for everyday driving, but lacked the stopping power of higher-performance Impreza variants. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The 1.6i Lineartronic Impreza was generally well-received as a practical and economical option within the Impreza range. Critics praised its fuel efficiency and the security of Subaru’s all-wheel drive system. However, the engine’s lack of power was a common criticism, particularly when compared to the 2.0-liter models. The CVT transmission, while smooth, wasn’t universally liked, with some reviewers finding it less engaging than a traditional automatic. Compared to the 2.0-liter Impreza, the 1.6i offered significantly better fuel economy but at the cost of performance. The 1.6i also represented a more affordable entry point into the Impreza lineup.
Legacy
The FB16 engine, while not as renowned as Subaru’s turbocharged engines, proved to be a relatively reliable unit. Common issues were generally minor and related to routine maintenance items. The Lineartronic CVT, when properly maintained with regular fluid changes, also demonstrated reasonable durability. In the used car market, the Impreza 1.6i Lineartronic represents a budget-friendly option for buyers seeking a reliable and all-weather capable compact sedan. Its fuel efficiency and relatively low running costs make it an attractive choice for those prioritizing practicality over performance. However, potential buyers should be aware of the engine’s limited power output and the CVT’s unique driving characteristics.
