What to Expect From the 2025 Subaru Forester’s Engine Specs

2025 Subaru Forester Engine Size and Specs Overview

When Subaru rolls out the next‑generation Forester, the first thing most enthusiasts ask about is the powertrain. The 2025 Subaru Forester engine size and specs are still under wraps, but the automaker has given enough clues to sketch a reasonable picture. Historically, the Forester has paired a horizontally opposed “boxer” four‑cylinder with either a naturally aspirated or turbocharged setup, and the 2025 model appears poised to follow that formula while nudging efficiency and output a notch higher.

Core Engine Options Likely on Offer

Two configurations are expected to dominate the lineup:

• 2.5‑liter naturally aspirated boxer – This has been the workhorse for the current generation, delivering a smooth torque curve and the low‑center‑of‑gravity feel Subaru drivers love.
• 2.4‑liter turbocharged boxer – A smaller displacement with forced induction could replace the outgoing 2.0‑liter turbo, offering a blend of peppy acceleration and respectable fuel economy.

Both engines will probably retain Subaru’s signature flat‑four layout, which helps keep the vehicle’s handling balanced, especially when paired with the brand’s standard all‑wheel‑drive system.

Performance Numbers – What the Rumors Suggest

Exact horsepower and torque figures haven’t been confirmed, but industry chatter points to a modest bump over the current model. Expect the naturally aspirated unit to sit somewhere in the 170‑180 hp range, while the turbocharged version could edge toward 250 hp, depending on boost pressure and tuning.

Torque will likely follow a similar pattern, with the larger engine delivering a broader low‑end pull that feels natural in city traffic, and the turbo offering a sharper surge for highway passing.

Fuel Efficiency and Emissions Outlook

Subaru has been tightening its emissions targets, so the 2025 Forester should see improvements in fuel consumption. The naturally aspirated 2.5‑liter engine may achieve roughly 28‑30 mpg combined, while the turbocharged 2.4‑liter could land in the high‑20s, thanks to cylinder deactivation and a more advanced variable valve timing system.

Both powerplants are expected to meet—or slightly exceed—Euro 6d and U.S. Tier 3 standards, thanks to tighter combustion control and a revamped exhaust after‑treatment package.

Transmission Pairings and Drive Modes

Subaru will likely continue offering a six‑speed manual for purists, though the majority of buyers will gravitate toward the CVT that has become standard across the range. The new CVT should feature a “Sport” mode that holds gears longer, giving the turbocharged engine a more engaging feel without sacrificing the smoothness the transmission is known for.

All‑wheel‑drive will remain a default feature, but a new “Intelligent Torque Split” system may appear, automatically adjusting torque distribution based on wheel slip, road conditions, and driver input.

How It Stacks Up Against the Previous Generation

Comparing the upcoming model to the 2022‑2024 Forester reveals a few clear trends:

• Engine displacement stays in the same ballpark, but the addition of a turbo‑charged option suggests a shift toward higher performance without a massive increase in size.
• Fuel‑economy figures are projected to improve by 1‑2 mpg, reflecting Subaru’s incremental efficiency gains.
• Technology integration—such as a larger infotainment screen and a more sophisticated driver‑assist suite—will complement the mechanical updates, making the 2025 Forester feel more contemporary.

What Buyers Should Keep in Mind

If you’re eyeing the 2025 Subaru Forester, consider how you’ll use the vehicle. Those who prioritize rugged, everyday practicality may find the naturally aspirated engine perfectly adequate, especially when paired with the CVT’s smooth delivery. Meanwhile, drivers who crave a bit more zip for weekend getaways might gravitate toward the turbocharged option, assuming it’s paired with the sport‑tuned CVT.

Pricing hasn’t been disclosed, but Subaru typically positions the Forester in the compact‑SUV segment’s mid‑range, meaning you’ll likely see a price gap of a few thousand dollars between the base and turbo models.

Frequently Asked Questions

Will the 2025 Forester offer a hybrid powertrain?

As of now, Subaru has not announced a hybrid version for the 2025 Forester. The company is focusing on refining its traditional boxer engines, though a hybrid could appear in later years as part of a broader electrification strategy.

How does the new engine affect the Forester’s off‑road capability?

The boxer layout, combined with standard all‑wheel‑drive, maintains the low‑center‑of‑gravity balance that gives the Forester its reputation for confidence on loose surfaces. The turbocharged option may even improve low‑speed torque, which can be helpful when navigating steep, uneven terrain.

What safety tech will accompany the new engine?

Expect Subaru’s EyeSight suite to remain standard, featuring adaptive cruise control, lane‑keep assist, and pre‑collision braking. The newer “Intelligent Torque Split” system will likely integrate with these aids to enhance stability during abrupt maneuvers.

When can I expect official specs to be released?

Subaru typically unveils detailed powertrain numbers at its annual auto show or during a dedicated press event a few months before the model year hits showrooms. Keep an eye on announcements in the spring of 2025 for the final figures.
