The 6th gen 4Runner represents a significant evolution for Toyota’s rugged SUV, and understanding its powertrain is essential for any owner or enthusiast. This generation, produced from 2010 to 2023, moved away from the venerable 4.0-liter inline-six found in earlier models, ushering in a new era of capability and technology. The standard and optional engine configurations for this generation are a study in balancing fuel efficiency with the demanding off-road performance the 4Runner nameplate is famous for. This focus on durability and power defines the core engineering philosophy behind the 6G.
The Standard Powerplant: 4.0-Liter V6
The heart of the base and SR5 trims for the majority of the 6th generation production run is the 4.0-liter 1GR-FE V6 engine. This unit is a workhorse, renowned for its reliability and robustness, which aligns perfectly with the 4Runner’s intended use. Mated to a robust 5-speed automatic transmission, this powertrain delivers a capable blend of on-road refinement and off-road grunt. While not the most powerful option available, it provides more than adequate power for daily driving, towing, and navigating challenging terrain with confidence.
Performance Specifications and Towing Capacity
When equipped with the standard 4.0-liter V6, the 6th generation 4Runner produces 270 horsepower and 278 lb-ft of torque. This output enables the vehicle to tow up to 5,000 pounds when properly equipped, making it suitable for hauling boats, small campers, or trailers. The power delivery is smooth and predictable, giving drivers confidence in both low-speed crawling situations and highway merging. The durability of this engine means it has become a favorite among those who prioritize longevity and low-cost ownership over raw speed.
The Optional Powerhouse: 4.0-Liter V6 with VVT-i For model years 2010 through 2013, Toyota offered an updated version of the 4.0-liter engine featuring Toyota’s Variable Valve Timing with intelligence (VVT-i) technology. This seemingly small change had a significant impact on performance and efficiency. By adjusting the timing of the intake valves, the engine could optimize its performance curve across different RPM ranges. This resulted in a slight increase in power and a noticeable improvement in fuel economy, bridging the gap between capability and modern engineering standards. Enhanced Efficiency and Driving Dynamics The addition of VVT-i allowed the 4Runner to meet tightening emissions regulations without sacrificing its core off-road abilities. The engine delivered a more linear power band, which translated to better responsiveness when climbing rocks or navigating steep inclines. Owners of these specific model years often highlight the VVT-i 4.0L as the ideal balance of the old-school reliability and new-school efficiency. This powertrain remains a top choice for those seeking a dependable yet refined 6th gen 4Runner. The TRD Pro Trim: Unleashing the 4.0-Liter’s Potential

The pinnacle of the 6th generation 4Runner lineup is the TRD Pro trim, which transforms the standard SUV into a factory-built off-road machine. The 4.0-liter V6 found in the TRD Pro is not a mere afterthought; it is meticulously tuned to deliver a more aggressive driving experience. With enhanced cooling systems and a unique exhaust note, this version of the engine is built to withstand the rigors of extreme off-roading while maintaining daily usability.
