2017 Subaru Impreza: Complete Performance and Design Analysis

The automotive landscape welcomed a significantly reimagined contender when Subaru introduced the fifth-generation Impreza for the 2017 model year. This generation represented a watershed moment for the nameplate, departing from the design philosophy of previous iterations to establish a vehicle that balances performance credentials, practical utility, and technological advancement. The overhaul extended far beyond cosmetic adjustments, touching every dimension of the driving experience from structural engineering to interior ergonomics.

Structural Foundation and Engineering Innovation

The foundation of any high-performing vehicle begins with its underlying structure, and Subaru invested considerable effort in reimagining the Impreza’s platform. The 2017 model features a chassis constructed with 70 percent greater rigidity compared to its 2016 predecessor, achieved through enhanced structural design and strategic placement of reinforcement materials. This substantial improvement in torsional rigidity fundamentally alters how the vehicle responds to dynamic driving inputs and contributes to the sense of solidity communicated through the steering wheel and chassis feedback.

Remarkably, engineers accomplished this structural enhancement while maintaining weight discipline. Despite the addition of high-strength steel components distributed throughout the unibody structure and the incorporation of more sophisticated suspension components, the new Impreza weighs within 100 pounds of the fourth-generation model. This achievement reflects the sophisticated engineering approach Subaru adopted, ensuring that structural gains did not translate into a penalty at the pump or in acceleration metrics.

The platform extension strategy, where engineers repositioned the wheels farther apart, resulted in a wheelbase that increased measurably. This adjustment provided dual benefits: enhanced interior spaciousness for rear passengers and improved handling stability through increased track width. The extended wheelbase also contributed to superior ride quality by allowing for more compliant suspension geometry that maintains composure over surface irregularities.

Suspension Architecture and Ride Quality Characteristics

The suspension system represents one of the most significant areas of development for this generation. Subaru implemented a control-arm suspension design that departs from the simpler torsion-beam rear axles common in the compact segment. This design choice necessitated different packaging considerations but delivered tangible benefits in handling dynamics and ride comfort.

A particularly innovative aspect of the suspension tuning involves the mounting strategy for the rear stabilizer bar. By attaching the stabilizer bar directly to the chassis body rather than through conventional bushing systems, Subaru created a more communicative suspension that responds precisely to driver input while filtering out unwanted vibration and harshness. This approach proved particularly effective at managing the body roll phenomenon, with engineering measurements indicating a 50 percent reduction in lateral body movement during cornering.

The suspension calibration process involved extensive testing over varied road surfaces, including the challenging terrain near San Diego where Subaru conducted vehicle evaluations. The resulting tune delivers a vehicle that feels substantially planted through high-speed transitions while maintaining a compliant demeanor when traversing broken pavement and highway expansion joints.

Steering Response and Handling Dynamics Enhancement

The steering system underwent significant recalibration, with engineers reducing the steering ratio from 16:1 in the previous generation to 13:1 in the new model. This modification, combined with suspension adjustments aimed at reducing the delay between steering input and vehicle response, fundamentally transformed the driving character. The result manifests as a steering system that feels more responsive and communicative, particularly during spirited driving on mountain roads or technical courses.

Engineers benchmarked the previous Impreza’s handling characteristics against established competitors including the Audi A3, Ford Focus, Mazda3, and Honda Civic, identifying significant gaps in responsiveness and feedback. The new platform addresses these shortcomings through a combination of reduced friction in the steering column, optimized suspension mounting points, and refined steering feel through the development of appropriate feedback characteristics.

Testing through performance slalom courses revealed substantial improvements in agility and body control. The vehicle navigates these technical tests with a glued-to-pavement feel and remarkable balance, demonstrating that Subaru successfully narrowed the performance gap with acknowledged handling leaders in the segment.

Engine Performance and Transmission Systems

The 2017 Impreza retains the familiar 2.0-liter horizontally-opposed four-cylinder engine, now producing 152 horsepower and 145 pound-feet of torque. While these figures may not appear startling in isolation, the engine exhibits characteristics that prove more engaging in real-world driving contexts than acceleration statistics alone suggest.

The throttle response demonstrates crispness and precision, with minimal delay between pedal input and power delivery. This responsiveness proves particularly valuable during moderate-speed maneuvers where progressive throttle application allows drivers to modulate speed through engine power rather than relying primarily on brake application. Combined with the improved steering response, this throttle characteristic creates a vehicle that feels more engaging and connected to the driver’s intentions.

Subaru offers two transmission options. The base configuration features a five-speed manual transmission, maintaining the brand’s commitment to enthusiast drivers who value direct mechanical engagement. The alternative continuously variable transmission (CVT), marketed as Lineartronic, provides a more refined alternative that mimics traditional automatic operation. Notably, the CVT earned accolades for its convincing simulation of a conventional stepped transmission, avoiding the drone-like character that plagued earlier CVT applications.

Acceleration figures show the Impreza achieving 0-60 mph in approximately 9.6 seconds, with a quarter-mile time of 17.4 seconds. While these metrics place the vehicle in the competent rather than thrilling category, real-world driving rarely demands such maximum effort, and the motor’s responsive character makes steady-state acceleration feel more stimulating than numbers indicate.

Fuel Efficiency and Consumption Performance

Fuel economy represents a significant consideration for compact car buyers, and the 2017 Impreza delivers impressive efficiency relative to its size and weight. The Environmental Protection Agency rates the vehicle at 28 city and 37 highway miles per gallon, with a combined figure of 31 mpg. Real-world owner reports indicate that careful drivers often exceed these figures, with several owners documenting consistent highway fuel economy approaching 37-40 mpg.

The efficiency achievement reflects the engine’s modest displacement, the transmission’s optimization, and the reduced aerodynamic drag resulting from the restyled exterior. This combination delivers a compelling equation for owners seeking to minimize fuel expenditure without sacrificing driving engagement or practical utility.

Interior Design and Cabin Quality Elevation

The cabin underwent significant transformation, departing from the spartan appointments of previous generations toward a more contemporary aesthetic. Material quality improved noticeably, with soft-touch surfaces replacing harder plastics in areas where occupants make frequent contact. The instrument panel presents information in a clear, logically organized fashion, reducing the cognitive load of operating vehicle systems.

Seating comfort represents an area where the new Impreza particularly excels. Front seats provide adequate support for extended driving, with optional heating functionality for cold-weather operation. The rear seating area expanded measurably, offering genuine accommodation for adult passengers rather than serving merely as an afterthought. The improved legroom and headroom result from the platform’s extended wheelbase and refined packaging.

Cargo capacity stands at 20.8 cubic feet with the rear seats in their upright position, though maximum capacity with seats folded approaches 55.3 cubic feet. This versatility makes the hatchback variant particularly appealing to owners requiring occasional hauling capability without the fuel economy penalty and higher purchase price of conventional cargo-oriented vehicles.

Safety Architecture and Driver Assistance Technology

Subaru’s EyeSight Driver Assist Technology represents a standout feature, providing adaptive cruise control and lane-keeping assistance that operate more intuitively than many competitors’ systems. The adaptive cruise control maintains appropriate spacing from preceding vehicles while demonstrating remarkable restraint in avoiding abrupt accelerations and decelerations. Lane-keeping assistance operates transparently, providing gentle steering corrections without imposing an intrusive presence.

Additional safety features available on higher trim levels include blind-spot monitoring and rear cross-traffic alert capabilities. These systems provide meaningful assistance during parking maneuvers and lane changes, particularly valuable in urban driving contexts where visibility limitations create hazardous situations.

The structural enhancements mentioned previously, particularly the increased rigidity and strategic placement of high-strength materials, provide a protective shell that complements the electronic safety systems. This multi-layered approach to occupant protection reflects modern safety philosophy that combines passive structural protection with active accident avoidance technologies.
