2025 Toyota 4Runner Engine Comparison
May 12 2025,

The all-new sixth-generation 2025 Toyota 4Runner arrives built on Toyota's TNGA-F global truck platform. This foundation—shared with the Tacoma, Land Cruiser, Tundra, and Sequoia—boosts structural rigidity, enhances ride comfort, and improves on-road handling while maintaining the 4Runner's off-road capabilities.
Two distinct powertrains define this new generation. You can opt for the standard i-FORCE turbocharged engine or choose the available i-FORCE MAX hybrid system. Both deliver strong power with different characteristics that suit various driving needs and preferences.
Standard Power: The i-FORCE 2.4L Turbocharged Engine
The standard 2025 Toyota 4Runner comes equipped with the i-FORCE turbocharged 2.4-litre four-cylinder engine. This powertrain generates 278 horsepower and up to 317 lb-ft of torque, providing ample power for everyday driving and weekend off-road trips.
The eight-speed automatic transmission pairs smoothly with this engine, delivering responsive shifts throughout the power range. You'll notice strong acceleration, particularly when tackling steep grades or merging onto highways.
This engine gives you practical towing capacity of 2722 kg (6000 lbs), letting you bring along boats, campers, or gear trailers on your adventures. For many drivers, this capability handles most recreational towing needs without compromise.
Based on your chosen trim level, this engine works with either part-time or full-time 4WD systems. The part-time system allows manual switching between 2WD and 4WD as conditions change, while the full-time system automatically adjusts power distribution for optimal traction.
Dynamic Capability: The i-FORCE MAX Hybrid Powertrain
For those wanting additional muscle, the available i-FORCE MAX hybrid powertrain amplifies the 2025 4Runner's capabilities. This system generates up to 326 horsepower and an impressive 465 lb-ft of torque—approximately 50% more torque than the standard engine option.
The hybrid system pairs the turbocharged 2.4-litre engine with electric motor technology for quick response and efficient operation. The immediate electric torque makes a real difference during slow-speed off-road maneuvers and when navigating technical trails.
You'll find this powertrain on select 2025 4Runner models, including the i-FORCE MAX TRD Pro, TRD Off Road Premium, Platinum, and Trailhunter. Each configuration targets specific driving priorities with thoughtfully selected features.
If you need serious towing functionality, the TRD Pro and Trailhunter models with i-FORCE MAX include practical towing additions such as the trailer brake controller and trailer backup guide with straight path assist for added confidence.
Real-World Performance Differences
Your typical driving conditions should guide your powertrain choice. The standard i-FORCE engine delivers strong performance for most situations with plenty of power for daily commutes, weekend getaways, and pulling moderate trailers.
The i-FORCE MAX hybrid system provides noticeably stronger acceleration, better off-road control, and more assured towing. You'll also appreciate the quieter operation and smoother power delivery, particularly in city traffic conditions.
Driving feel differs between the two options as well. The standard i-FORCE engine offers straightforward, predictable power, while the i-FORCE MAX hybrid delivers instant response from a stop and consistent acceleration across the power range due to its electric assistance.
Find Your Perfect 4Runner Powertrain
The 2025 Toyota 4Runner offers two capable engine options that build on Toyota's strong reliability record. The standard i-FORCE turbo delivers solid performance at a more approachable price, while the i-FORCE MAX hybrid provides additional capability for drivers who regularly push their SUV to its limits.
