The 2015 Subaru Impreza comes equipped with a 2.0-liter naturally aspirated flat-four engine, designated as the FB20. This horizontally-opposed boxer engine produces 148 horsepower at 6,200 RPM and 145 lb-ft of torque at 4,200 RPM. The FB20 features direct fuel injection, dual overhead cams, and Subaru’s Active Valve Control System (AVCS) on both intake and exhaust camshafts. This engine is paired with either a 5-speed manual transmission or Subaru’s Lineartronic CVT automatic transmission, and comes standard with Subaru’s Symmetrical All-Wheel Drive system across all trim levels.

The 2015 Subaru Impreza shares most parts with the 2012-2016 fourth-generation Impreza models. Engine components from the FB20 are largely interchangeable across these years, though minor updates occurred mid-cycle. Body panels, interior components, and suspension parts are generally compatible within this generation. Some electrical components and infotainment systems may vary between model years. The CVT transmission is compatible across 2012-2016 models, while manual transmission parts interchange well. Always verify part numbers for critical components, as Subaru made running changes throughout production that can affect compatibility even within the same model year.

The FB20 2.0L engine in the 2015 Impreza is generally reliable when properly maintained, representing a significant improvement over previous Subaru engines. Regular oil changes every 6,000 miles with full synthetic oil are crucial for longevity. The engine is less prone to the catastrophic head gasket failures that plagued earlier Subaru engines, though minor seepage can still occur at higher mileages. Key maintenance items include keeping up with spark plug changes every 60,000 miles and addressing carbon buildup through periodic intake cleaning. With proper care, these engines commonly exceed 200,000 miles, though the CVT transmission may require attention before the engine does.
