The 2015 Forester engine lineup represented a significant evolution for Subaru’s compact crossover, blending refined performance with the brand’s signature standard all-wheel drive. This model year solidified the boxer engine’s reliability and efficiency, offering drivers a blend of capability and comfort that remained true to the brand’s rally heritage. Understanding the nuances of the 2015 powertrain options is essential for buyers seeking a dependable, engaging driving experience.
Engine Specifications and Performance
The heart of the 2015 Forester is the horizontally-opposed 2.0-liter FB20 boxer engine, a substantial upgrade over its predecessor. This unit produces 150 horsepower and 136 lb-ft of torque, providing a noticeable improvement in both power and fuel efficiency. The engine is mated to a standard Subaru Lineartronic continuously variable transmission (CVT), which delivers smooth power delivery and optimal economy across a range of driving conditions.
Performance Metrics and Driving Dynamics
While not a sports car, the 2015 Forester offers a compelling balance of efficiency and responsiveness. The boxer engine’s low center of gravity contributes to the vehicle’s excellent handling and stability, especially in adverse weather. Acceleration is steady and predictable, making it well-suited for highway merging and navigating everyday driving challenges with confidence.
Fuel Efficiency and Engineering
One of the standout features of the 2015 model year is its impressive fuel economy. The base model, equipped with standard all-wheel drive, achieves an estimated 26 mpg in the city and 33 mpg on the highway. This efficiency is a direct result of the engine’s design, which incorporates features like low-friction components and an eco-focused calibration that doesn’t compromise daily usability or performance.

Trim Levels and Engine Options
For the 2015 model year, Subaru offered the Forester in several trim levels, including the base, Premium, Limited, and Touring trims. Each trim built upon the standard 2.0-liter engine and CVT, adding features like leather upholstery, enhanced infotainment systems, and upgraded safety technology. The availability of the turbocharged 2.0XT engine in higher trims provided an option for drivers seeking increased power and a more assertive driving experience.
The 2.0XT Turbocharged Variant
The performance-oriented 2.0XT model utilizes a turbocharger to boost output to 170 horsepower and 170 lb-ft of torque. This variant delivers a more spirited drive, with quicker acceleration and a more robust engine note. It retains the same CVT transmission but features a more substantial cooling system to manage the increased thermal loads associated with forced induction.
Reliability and Maintenance
The 2015 Forester engine benefits from Subaru’s boxer design, which is inherently balanced and has demonstrated exceptional longevity in decades of vehicles. Regular maintenance, including timely oil changes and inspections, is key to ensuring the powertrain operates at peak efficiency. Owners often report high mileage with minimal issues, a testament to the engineering robustness of the platform.
Safety Integration with Powertrain
Sububishi’s standard Symmetrical All-Wheel Drive system is perfectly matched to the 2015 Forester’s engine, providing superior traction in various conditions. This integration enhances control during acceleration, particularly on wet or slippery surfaces. The electronic stability control system works in concert with the powertrain to maintain confidence-in-handling, making the Forester a top safety choice without sacrificing driving dynamics.
