The Subaru Impreza IV Hatchback, specifically the 1.6i variant with 114 horsepower and a Lineartronic (CVT) transmission, was produced from 2015 to 2016 as part of the facelifted fourth generation (GE/GH/GR/GV) of the Impreza. This model represented Subaru’s entry point into the Impreza range in many European and Asian markets, offering a blend of practicality, Subaru’s signature symmetrical all-wheel drive, and relatively fuel-efficient motoring. It sat below the more powerful 2.0-liter naturally aspirated and turbocharged models in the lineup, targeting buyers prioritizing economy and ease of use over outright performance. The facelift brought revised styling, improved interior materials, and updated safety features to the Impreza range.

Powertrain & Engine Architecture
The heart of the 1.6i Impreza is the FB16 1.6-liter horizontally-opposed (Boxer) four-cylinder engine. This engine is a key component of Subaru’s engineering philosophy, known for its inherent balance and smooth operation. The FB16 utilizes multi-point fuel injection and a relatively high compression ratio of 10.5:1 to maximize efficiency. The engine produces 114 horsepower at 5600 rpm and 150 Nm (110.63 lb-ft) of torque at 4000 rpm. Paired with this engine is Subaru’s Lineartronic continuously variable transmission (CVT). This CVT is designed to provide smooth, stepless gear changes, optimizing fuel economy and drivability. Unlike traditional automatic transmissions, CVTs don’t have fixed gear ratios, instead using a belt and pulley system to provide an infinite number of ratios within a certain range. The Lineartronic in the Impreza is programmed with simulated ‘steps’ to mimic the feel of a conventional automatic, addressing some driver preferences.
Driving Characteristics
The 1.6i Lineartronic Impreza prioritizes comfort and fuel efficiency over sporty performance. Acceleration from 0-60 mph takes around 12 seconds, and the top speed is 111.23 mph. The CVT transmission contributes to a smooth driving experience, but it can sometimes feel less responsive than a traditional automatic or manual gearbox, particularly during quick acceleration. The Lineartronic transmission is programmed to hold lower ‘ratios’ when accelerating, but it lacks the immediate punch of a geared transmission. The symmetrical all-wheel drive system provides excellent traction in various weather conditions, a hallmark of Subaru vehicles. The steering is light and precise, making it easy to maneuver in urban environments. Overall, the driving experience is geared towards everyday usability rather than enthusiastic driving.
Equipment & Trim Levels
The 1.6i trim level typically served as the base model in many markets. Standard equipment generally included air conditioning, power windows and mirrors, a basic audio system with USB connectivity, and alloy wheels. Safety features were comprehensive, including ABS brakes, electronic stability control, and multiple airbags. Optional extras often included a sunroof, upgraded audio system, and navigation system. Interior upholstery was typically cloth, and the dashboard featured a functional but relatively simple design. The focus was on providing a well-equipped and practical vehicle at an accessible price point.
Chassis & Braking
The Impreza IV Hatchback utilized a MacPherson strut front suspension and a double-wishbone rear suspension. This setup provides a good balance between ride comfort and handling. The 1.6i model typically featured smaller diameter wheels and tires compared to higher-spec Imprezas, contributing to a more comfortable ride. Braking duties were handled by ventilated discs at the front and solid discs at the rear. ABS (Anti-lock Braking System) was standard, enhancing braking performance and safety. The suspension was tuned for everyday driving, prioritizing comfort over aggressive 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, comfortable ride, and standard all-wheel drive. However, some reviewers noted the engine’s lack of outright power and the CVT transmission’s sometimes-sluggish response. Compared to the 2.0-liter Impreza models, the 1.6i offered lower running costs but sacrificed performance. Against competitors like the Volkswagen Golf or Ford Focus, the Impreza stood out with its standard all-wheel drive, a feature not commonly found in that segment. Fuel economy figures of around 39.9 US mpg combined were competitive for its class.
Legacy
The FB16 engine, while not known for being a powerhouse, has proven to be a relatively reliable unit when properly maintained. The Lineartronic CVT transmission, however, requires regular fluid changes to ensure longevity. Used examples of the 1.6i Impreza are generally affordable and represent a good value for buyers seeking a practical and reliable hatchback with all-wheel drive. Common issues reported include occasional CVT hesitation and minor oil leaks. Overall, the 1.6i Lineartronic Impreza remains a viable option for those seeking a dependable and fuel-efficient vehicle, particularly in regions where all-wheel drive is highly valued.
