The Subaru Crosstrek II 2.0 Plug-in Hybrid, produced from 2018 to 2020, represents Subaru’s entry into the burgeoning plug-in hybrid crossover market in North America and Europe. Built upon the Subaru Global Platform (a revised version of the 1HX0/A3 platform shared with the Impreza), this variant aimed to offer a balance of all-wheel-drive capability, fuel efficiency, and a degree of electric-only driving. Positioned as a premium offering within the Crosstrek lineup, it sat above the standard 2.0-liter gasoline model in terms of price and technology. This model was primarily sold in markets with incentives for hybrid and electric vehicles, including the United States, Canada, and select European countries.

Powertrain & Engine Architecture
The Crosstrek II Plug-in Hybrid utilizes a unique powertrain combining a 2.0-liter naturally aspirated boxer engine (FB20 code) with an electric motor integrated into the Lineartronic continuously variable transmission (CVT). The FB20 engine, a hallmark of Subaru’s engineering, features direct injection and Dual Active Valve Control System (DAVCS) for optimized efficiency and power delivery. The electric motor provides supplemental power and allows for all-electric driving for up to 27.4 kilometers (17.03 miles). The 8.8 kWh lithium-ion battery pack is located under the trunk floor, slightly reducing cargo capacity compared to the standard Crosstrek. The system intelligently switches between electric, gasoline, and combined power modes, prioritizing electric operation when possible. The Lineartronic CVT is specifically tuned to work seamlessly with both the engine and electric motor, providing smooth and efficient power delivery.
Driving Characteristics
The 148 horsepower combined output of the 2.0-liter engine and electric motor delivers adequate, though not exhilarating, performance. Acceleration is noticeably quicker than the standard 2.0-liter Crosstrek, particularly at lower speeds when the electric motor provides instant torque. The Lineartronic CVT, while smooth, lacks the responsiveness of a traditional automatic transmission. In electric-only mode, the Crosstrek II Plug-in Hybrid offers a quiet and refined driving experience, ideal for city commuting. The all-wheel-drive system provides confident handling in various weather conditions, a key Subaru attribute. Compared to the higher-output 2.5-liter engine option available in later Crosstrek models, this plug-in hybrid variant prioritizes fuel efficiency over outright performance.
Equipment & Trim Levels
The Crosstrek II Plug-in Hybrid typically came well-equipped, reflecting its premium positioning. Standard features included automatic climate control, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, Subaru’s EyeSight driver-assist technology (including adaptive cruise control, lane departure warning, and automatic emergency braking), and heated front seats. Higher trim levels added features such as a premium audio system, leather upholstery, and a power driver’s seat. The interior design was functional and modern, with a focus on practicality and ease of use.
Chassis & Braking
The Crosstrek II Plug-in Hybrid utilizes a McPherson strut front suspension and a double-wishbone rear suspension, providing a comfortable and controlled ride. The suspension tuning is geared towards everyday usability rather than sporty handling. Ventilated disc brakes are used on all four wheels, providing adequate stopping power. The added weight of the battery pack and electric motor necessitates a slightly firmer suspension setup compared to the standard Crosstrek. The electric power steering provides light and precise steering feel.
Market Reception & Comparison
The Crosstrek II Plug-in Hybrid received generally positive reviews, with critics praising its fuel efficiency, all-wheel-drive capability, and standard safety features. However, some reviewers noted the relatively limited all-electric range and the lack of a truly engaging driving experience. Compared to the standard 2.0-liter Crosstrek, the plug-in hybrid offered significantly improved fuel economy and the ability to drive in electric-only mode, but at a higher price point. Compared to other plug-in hybrid crossovers available at the time, the Crosstrek II Plug-in Hybrid offered a unique combination of Subaru’s renowned all-wheel-drive system and a relatively affordable price.
Legacy
The Subaru Crosstrek II Plug-in Hybrid represented an important step for Subaru in the electrification of its vehicle lineup. While production was relatively short-lived, the model demonstrated Subaru’s commitment to offering environmentally friendly vehicles. On the used car market, these models hold their value reasonably well, particularly those with low mileage and well-maintained batteries. The FB20 engine is known for its reliability, and the Lineartronic CVT, while requiring regular maintenance, has proven to be a durable transmission. The Crosstrek II Plug-in Hybrid remains a viable option for buyers seeking a fuel-efficient and capable all-wheel-drive crossover.
