The Subaru Impreza IV Sedan 1.6i Sport, 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 hatchback variants and higher-performance trims – the 1.6i Sport offered a blend of Subaru’s signature all-wheel drive capability with a focus on fuel efficiency and affordability. This variant was primarily marketed in regions where compact sedans were favored, and it served as a practical and reliable transportation option for individuals and small families. It utilized Subaru’s Lineartronic continuously variable transmission (CVT) paired with the naturally aspirated 1.6-liter boxer engine.

Powertrain & Engine Architecture
The heart of the Impreza 1.6i Sport 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 double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The engine produces 114 horsepower at 5600 rpm and 150 Nm (110.63 lb-ft) of torque at 4000 rpm. This engine was designed with fuel efficiency in mind, incorporating features like optimized combustion chamber design and reduced internal friction. Paired with the FB16 is Subaru’s Lineartronic CVT, a continuously variable transmission that offers seamless gear changes and contributes to improved fuel economy. The Lineartronic transmission in this application features simulated shift points to provide a more familiar driving experience for those accustomed to traditional automatic transmissions.
Driving Characteristics
The 1.6i Sport’s driving experience is characterized by its smooth and predictable nature. The Lineartronic CVT eliminates harsh gear shifts, providing a comfortable ride, especially in urban environments. However, the 114 horsepower output and the CVT’s programming result in a somewhat leisurely acceleration. 0-60 mph takes approximately 12 seconds, and the car has a top speed of 112.47 mph. Compared to higher-performance Impreza variants like the 2.5i or WRX models, the 1.6i Sport feels noticeably less powerful. The CVT is programmed to prioritize fuel efficiency, which can sometimes lead to the engine ‘hunting’ for the optimal gear ratio under hard acceleration. Despite the modest power output, Subaru’s symmetrical all-wheel drive system provides excellent traction and stability in various weather conditions, a hallmark of the Impreza lineup.
Equipment & Trim Levels
The 1.6i Sport trim typically included standard features such as air conditioning, power windows and locks, a basic audio system with auxiliary input, and alloy wheels. Safety features included ABS, electronic brake-force distribution, and multiple airbags. Interior upholstery was typically cloth, and the dashboard featured a straightforward design with easy-to-use controls. Optional extras available for the 1.6i Sport could include a sunroof, upgraded audio system, and keyless entry. The “Sport” designation primarily referred to the exterior styling, which included minor cosmetic enhancements like a rear spoiler and unique wheel designs.
Chassis & Braking
The Impreza IV Sedan 1.6i Sport utilizes an independent McPherson strut suspension in the front and a double-wishbone suspension in the rear. This suspension setup provides a comfortable ride and decent handling characteristics. The front brakes are ventilated discs, while the rear brakes are solid discs. The car’s relatively lightweight construction (1350 kg / 2976.24 lbs) helps to compensate for the modest engine power. Stabilizer bars are present on both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The Impreza 1.6i Sport was generally well-received as an affordable and practical entry-level option in the compact sedan segment. Critics praised its standard all-wheel drive system and fuel efficiency. However, some reviewers noted the engine’s lack of power and the CVT’s sometimes uninspiring driving experience. Compared to other Impreza trims, such as the 2.5i, the 1.6i Sport offered lower running costs but sacrificed performance. Against competitors like the Honda Civic, Toyota Corolla, and Mazda3, the Impreza 1.6i Sport stood out with its standard all-wheel drive, a feature not commonly found in this class.
Legacy
The FB16 engine, while not known for being a powerhouse, has proven to be a relatively reliable powertrain. Common maintenance items include regular oil changes and timing belt replacements (typically around 100,000 miles). The Lineartronic CVT, while generally durable, requires proper fluid maintenance to prevent issues. In the used car market, the Impreza 1.6i Sport represents a good value for buyers seeking a reliable and fuel-efficient all-wheel drive sedan. Its simplicity and relatively low maintenance costs make it an attractive option for those looking for a practical and affordable vehicle.
