The Subaru Forester V, specifically the Wilderness 2.5 model introduced with the 2021 facelift, represents a significant iteration of Subaru’s popular compact SUV. Produced from September 2021 through 2024, this variant aimed to enhance the Forester’s already capable all-wheel-drive system and rugged appeal. Positioned as a more adventurous trim level within the Forester lineup, the Wilderness 2.5 targeted buyers seeking increased off-road capability and a more outdoorsy aesthetic without sacrificing the Forester’s renowned practicality and safety. It builds upon the fifth-generation Forester (introduced in 2018) which utilizes Subaru’s Global Platform, offering improved rigidity and crash safety.

Powertrain & Engine Architecture
The heart of the 2021-2024 Forester Wilderness 2.5 is the FB25 2.5-liter naturally aspirated four-cylinder Boxer engine. This engine is a hallmark of Subaru’s engineering, known for its low center of gravity and smooth operation. The FB25 utilizes direct fuel injection, maximizing combustion efficiency and contributing to improved fuel economy. The engine also features Subaru’s Dual Active Valve Control System (DAVCS), which optimizes valve timing for both intake and exhaust, enhancing both power and torque across the rev range. The engine produces 182 horsepower at 5,800 rpm and 176 lb-ft of torque at 4,400 rpm. Paired with the engine is a Lineartronic CVT (Continuously Variable Transmission). This transmission is designed to simulate traditional gear shifts while offering seamless acceleration and optimized fuel efficiency. The Lineartronic CVT in the Wilderness model features enhanced durability and revised programming to better suit the vehicle’s off-road intentions.
Driving Characteristics
The Wilderness 2.5’s combination of the 2.5-liter Boxer engine and Lineartronic CVT delivers a comfortable and predictable driving experience. While not a performance-oriented setup, the engine provides adequate power for everyday driving and highway cruising. The CVT effectively manages the engine’s powerband, offering smooth acceleration. Compared to earlier Forester models with manual transmissions, the Wilderness 2.5 prioritizes ease of use and fuel efficiency over outright speed. The CVT’s continuously variable ratios allow the engine to operate in its most efficient range, contributing to the combined fuel economy of 26.1 US mpg. However, some drivers may find the CVT’s simulated shift points less engaging than a traditional automatic transmission. The Wilderness trim’s gearing is optimized for low-speed crawling and off-road traction, potentially sacrificing some responsiveness at higher speeds.
Equipment & Trim Levels
The Wilderness trim level came standard with a host of features designed to enhance its off-road capability and appeal to outdoor enthusiasts. Standard equipment included all-weather floor liners, raised roof rails, a front skid plate, and unique exterior styling cues such as matte black cladding and copper-colored accents. Inside, the Wilderness featured StarTex water-repellent upholstery, providing durability and ease of cleaning. Available options included a power moonroof, a premium Harman Kardon audio system, and Subaru’s EyeSight driver-assist technology suite, which includes adaptive cruise control, lane departure warning, and automatic emergency braking. The dashboard configuration was consistent with other Forester V models, featuring a vertically oriented touchscreen infotainment system.
Chassis & Braking
The Wilderness 2.5 benefits from Subaru’s symmetrical all-wheel-drive system, which distributes power to all four wheels for optimal traction in various conditions. The suspension was specifically tuned for the Wilderness trim, with increased spring rates and revised dampers to improve off-road performance and handling. The front suspension utilizes McPherson struts with a coil spring and anti-roll bar, while the rear suspension employs a double-wishbone setup. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power. The Wilderness trim also features a slightly increased ride height (9.21 inches) compared to other Forester models, further enhancing its off-road capability.
Market Reception & Comparison
The Forester Wilderness 2.5 was generally well-received by automotive critics, who praised its enhanced off-road capability, rugged styling, and practical interior. Compared to other Forester trims, the Wilderness offered a more adventurous and capable alternative for buyers seeking a vehicle that could handle more than just paved roads. Fuel economy was comparable to other 2.5-liter Forester models, with the combined rating of 26.1 US mpg being competitive within the compact SUV segment. Reliability ratings for the FB25 engine and Lineartronic CVT have been generally positive, although some owners have reported minor issues with the CVT over the long term. Compared to the base Forester, the Wilderness commanded a higher price point, reflecting its added features and off-road enhancements.
Legacy
The Subaru Forester Wilderness 2.5 has established itself as a popular choice in the used car market, particularly among buyers seeking a capable and reliable all-wheel-drive SUV. The FB25 engine and Lineartronic CVT have proven to be relatively durable powertrains, although regular maintenance is crucial for long-term reliability. The Wilderness trim’s unique styling and enhanced off-road capability continue to appeal to outdoor enthusiasts. As Subaru continues to refine its Forester lineup, the Wilderness 2.5 represents a significant step in the model’s evolution, demonstrating the brand’s commitment to both practicality and adventure.
