The arrival of the 2025 Toyota 4Runner marks one of the most significant milestones in the history of the mid-size SUV segment. After a fifteen-year production run for the fifth generation, Toyota has finally introduced a completely redesigned version of its off-road icon. Built on the TNGA-F global truck platform, shared with the Tacoma, Land Cruiser, and Tundra, this new generation promises to modernize the 4Runner's legacy while maintaining the rugged, body-on-frame characteristics that have earned it a cult following for four decades.

Moving into the 2025 model year, the 4Runner undergoes a radical transformation in its powertrain, technology, and trim availability. While the classic silhouettes and the beloved power rear window remain, almost everything under the skin is new. This evolution reflects a broader industry shift toward efficiency and torque-rich turbocharged engines, paired with the sophisticated off-road hardware that today's overlanding enthusiasts demand.

A New Era of Power: Turbocharging and Hybridization

For years, the 4Runner relied on a naturally aspirated 4.0-liter V6 engine known for its bulletproof reliability but criticized for its dated efficiency and modest torque. The 2025 Toyota 4Runner retires the old V6 in favor of two distinct 2.4-liter turbocharged four-cylinder powerplants.

The standard engine is the i-FORCE turbocharged 2.4-liter four-cylinder, delivering 278 horsepower and 317 lb-ft of torque. This marks a substantial increase in torque compared to the outgoing model, providing better low-end pull for daily driving and light trail work. This engine is mated to an eight-speed automatic transmission, replacing the previous five-speed unit, which should result in smoother shifts and improved highway fuel economy.

For those seeking maximum performance, the i-FORCE MAX hybrid powertrain is the highlight of the lineup. It pairs the 2.4-liter turbo engine with a 48-hp electric motor integrated into the eight-speed transmission, drawing power from a 1.87-kWh NiMH battery pack. The system produces a combined 326 horsepower and a massive 465 lb-ft of torque. This torque figure is nearly double what the old V6 could manage, making it a compelling choice for towing and climbing technical obstacles. The hybrid system is standard on the TRD Pro, Trailhunter, and Platinum grades, and is available as an option on the TRD Off-Road and Limited.

The Strength of the TNGA-F Platform

The transition to the TNGA-F platform is arguably the most important structural change for the 2025 4Runner. This high-strength boxed steel ladder frame provides significantly more rigidity than the previous chassis. The increased stiffness allows Toyota to tune the suspension more precisely, improving on-road ride quality and handling without sacrificing the vehicle's legendary toughness.

One of the practical benefits of this new platform is an increased towing capacity. The 2025 4Runner is rated to tow up to 6,000 pounds, a 1,000-pound increase over the previous generation. This allows owners to pull larger campers, boats, or utility trailers with greater confidence. The rear suspension continues to use a multi-link coil setup, which balances load-carrying ability with the articulation needed for off-road environments.

Off-Road Hardware and Innovations

The 4Runner has always been a tool for adventure, and the new generation introduces several mechanical upgrades to enhance its capability. A key addition is the Stabilizer Disconnect Mechanism (SDM). This system allows the front anti-roll bar to be disconnected at the push of a button, significantly increasing wheel travel and articulation. This feature helps keep the tires in contact with the ground on uneven surfaces, improving traction in technical rock-crawling scenarios.

Approach and departure angles remain competitive, with the 2025 model offering up to a 32-degree approach angle and a 24-degree departure angle. Ground clearance reaches up to 10.1 inches on certain trims. The 4WD system is available in three configurations: RWD with an automatic limited-slip differential, part-time 4WD with an electronically controlled two-speed transfer case, and a full-time 4WD system featuring a center-locking differential (standard on the Platinum and optional on the Limited).

The Multi-Terrain Select (MTS) system now functions in both 4WD High and 4WD Low, offering adjustable settings for various surfaces like Mud, Dirt, and Sand. Additionally, the Crawl Control feature has been updated to operate more quietly and smoothly, acting as a low-speed cruise control for off-roading so the driver can focus entirely on steering.

Redefining the Interior Experience

Inside, the 2025 Toyota 4Runner sheds its utilitarian past for a cabin that is both functional and modern. The dashboard design is rugged and blocky, fitting the exterior aesthetic, but it is now dominated by advanced screens. An 8-inch touchscreen is standard, while a 14-inch Toyota Audio Multimedia system is available on higher trims. This system supports wireless Apple CarPlay and Android Auto, and features an intuitive interface that responds well to voice commands.

Drivers now benefit from a 7-inch gauge cluster on lower trims and a 12.3-inch fully digital instrument cluster on premium grades. The placement of controls remains ergonomic, with physical knobs for volume and climate control—a detail appreciated by those who wear gloves while driving or off-roading.

Utility remains a priority. The tumble-fold second-row seats help maximize cargo space, and the available third row allows for seating up to seven people on certain configurations. One of the standout features is the available 14-speaker JBL Premium Audio system, which includes a "JBL Flex" portable speaker that can be removed from the dash for use at a campsite or beach. The speaker is waterproof and dust-resistant, aligning perfectly with the vehicle's adventurous spirit.

The Trailhunter: A Turn-Key Overlander

The Trailhunter grade is perhaps the most exciting addition to the 2025 4Runner lineup. Developed specifically for long-duration off-grid adventures, the Trailhunter comes factory-equipped with components from some of the most respected names in the off-road industry.

It features Old Man Emu (OME) 2.5-inch forged pressure shocks with rear external remote reservoirs. These shocks are designed specifically to handle the extra weight of gear and accessories while maintaining control and comfort over rough terrain. The Trailhunter also includes a high-mounted air intake (snorkel) to protect the engine from dust and water, and an ARB-designed steel roof rack.

Protection is a priority for this trim. It features co-designed ARB rock rails and high-strength steel skid plates to protect the radiator, engine, fuel tank, and transfer case. Visually, the Trailhunter is distinguished by a bronze "TOYOTA" heritage grille and 33-inch tires that widen its stance. It also includes an onboard air compressor in the cargo area, allowing owners to easily adjust tire pressure after a day on the trails.

Safety and Driver Assistance

Every 2025 4Runner comes standard with Toyota Safety Sense 3.0 (TSS 3.0). This suite of active safety features represents a major upgrade in technology compared to the previous generation. Key features include:

  • Pre-Collision System with Pedestrian Detection: Can detect vehicles, pedestrians, and cyclists, providing automatic emergency braking if necessary.
  • Lane Departure Alert with Steering Assist: Helps keep the vehicle centered in its lane.
  • Full-Speed Range Dynamic Radar Cruise Control: Maintains a set distance from the vehicle ahead, even in stop-and-go traffic.
  • Lane Tracing Assist: Provides steering support to keep the vehicle in its lane when cruise control is active.
  • Proactive Driving Assist: Gently applies brakes or steering to help maintain distance or navigate curves.

TSS 3.0 uses improved sensors and cameras with a wider field of view, making the systems more effective in complex driving environments. These features are particularly useful for long highway stretches during road trips to remote destinations.

Practicality: Fuel Economy and Space

While official EPA numbers may vary based on driving conditions, the shift to four-cylinder engines is expected to improve the 4Runner's fuel efficiency significantly. The i-FORCE MAX hybrid system is targeted to achieve a combined rating in the neighborhood of 23 MPG, which is a notable improvement over the 17-18 MPG combined rating of the previous V6.

Cargo capacity remains a strong suit. With up to 90.2 cubic feet of space when the second-row seats are tumbled forward, the 4Runner provides ample room for camping gear, sports equipment, or groceries. The interior also features several clever storage solutions, including a hidden shelf in the dashboard and large door pockets. For those who enjoy car camping, the flat floor and large cargo area make it a viable option for sleeping inside the vehicle.

Making the Decision: Is the 2025 4Runner Right for You?

The 2025 Toyota 4Runner occupies a unique position in the market. It is more rugged and trail-focused than the Toyota Highlander, yet more modern and slightly more compact than the Sequoia. For those who require a vehicle that can handle a daily commute comfortably and then tackle a mountain pass on the weekend, the 4Runner remains a top contender.

The choice between the standard i-FORCE and the i-FORCE MAX hybrid will likely depend on your specific needs. If you do a lot of heavy towing or high-altitude driving, the extra torque of the hybrid system is worth the investment. However, for those looking for a traditional, slightly lighter SUV for general utility and trail use, the standard turbocharged engine offers plenty of power.

Collectors and enthusiasts will naturally gravitate toward the TRD Pro for its iconic styling and high-speed off-road prowess. Meanwhile, the Trailhunter is the obvious choice for those who plan on building a dedicated overlanding rig, as it saves the owner thousands of dollars in aftermarket parts and labor.
