Toyota redesigned the 4Runner from the ground up for 2025, and the results speak for themselves. The all-new sixth-generation model introduces hybrid power for the first time in 4Runner history. The i-FORCE MAX hybrid powertrain delivers 326 horsepower and 465 lb-ft of torque, making this the most powerful 4Runner ever built.

This power increase isn't just about bigger numbers. The hybrid system transforms how the 4Runner performs both on pavement and off-road. More torque means better capability when climbing steep grades or pulling heavy loads, while the electric motor provides instant response that makes daily driving more engaging.

How the i-FORCE MAX Hybrid System Works

The 4Runner Hybrid combines a 2.4-litre turbocharged four-cylinder engine with a 48-horsepower electric motor integrated into the eight-speed transmission. A 1.87-kWh nickel metal hydride battery pack stores energy from regenerative braking and engine operation.

This setup creates a total system output that exceeds what either component could deliver alone. The electric motor fills in power gaps during acceleration and provides additional torque when you need it most. The system operates automatically, switching between gas and electric power based on driving conditions.

Key hybrid components: 

• 2.4L turbocharged four-cylinder engine 
• 48 HP electric motor integrated into transmission 
• 1.87-kWh nickel metal hydride battery pack 
• Eight-speed automatic transmission 
• No external charging required

Power Comparison with Previous Generation

The new hybrid powertrain represents a significant step forward from the outgoing V6 engine. Previous 4Runner models used a naturally aspirated 4.0-litre V6 that produced less power and torque while consuming more fuel.

The i-FORCE MAX hybrid system delivers both more performance and better efficiency. This combination was previously difficult to achieve, but Toyota's hybrid technology makes it possible without compromising reliability.

Off-Road Performance Benefits

Extra power and torque directly improve off-road capability. The 465 lb-ft of torque helps when climbing steep rocky sections or powering through sand and mud. The electric motor provides immediate response without the lag that sometimes occurs with turbocharged engines.

4Runner Hybrid models include either part-time or full-time 4WD depending on the grade. Both systems work with the hybrid powertrain to deliver traction and control in challenging conditions. The electric motor's instant torque complements these mechanical systems.

Available off-road features include: 

• Multi-terrain select system 
• Downhill assist control 
• Crawl control for low-speed precision 
• Locking rear differential

Fuel Economy Improvements

Despite the significant power increase, the 4Runner Hybrid achieves better fuel economy than the previous V6 engine. The hybrid system's ability to shut off the gas engine during certain driving conditions reduces overall fuel consumption.

Fuel consumption ratings vary by grade and 4WD system:

The efficiency improvements become most noticeable during city driving and stop-and-go conditions where the electric motor contributes more power.

Grade Options and Configurations

The 2025 4Runner lineup includes eight different models, with four hybrid options available. Each hybrid grade targets different priorities and feature levels while sharing the same powertrain foundation.

Hybrid grades include TRD Sport Hybrid, TRD Off-Road Hybrid, Limited Hybrid, and Platinum Hybrid. Each adds specific equipment and styling elements while maintaining the core hybrid performance advantage.

The availability of both part-time and full-time 4WD systems across different grades lets buyers choose the drivetrain setup that matches their intended use.

Interior Space and Passenger Capacity

Power improvements don't come at the expense of interior practicality. The 2025 4Runner maintains its reputation for spacious seating and cargo capacity. Five- or seven-passenger configurations are available depending on grade selection.

The hybrid battery pack is positioned to minimize impact on interior space. Cargo area remains generous for gear and equipment, while passenger seating provides comfort for longer journeys.

TNGA-F Platform Benefits

The 2025 4Runner uses Toyota's TNGA-F global truck platform, shared with other Toyota trucks including the Tacoma, Land Cruiser, Tundra, and Sequoia. This platform provides increased strength and improved ride comfort compared to the previous generation.

The platform's design accommodates the hybrid system components while maintaining the rugged capability that 4Runner buyers expect. Body-on-frame construction continues to provide the durability needed for serious off-road use.

Technology Integration

Modern hybrid systems require sophisticated control systems to manage power delivery. The 4Runner Hybrid includes drive mode selection that adjusts powertrain behavior for different conditions. Sport, Eco, and Normal modes change how the gas engine and electric motor work together.

The system operates transparently, requiring no special driving techniques or maintenance routines beyond normal service intervals. Toyota designs hybrid components for long-term reliability in demanding conditions.
