2026 Toyota 4Runner Performance Specs: Turbocharged Muscle & i-FORCE MAX Hybrid Power

The sixth-generation 4Runner marks a turning point. Here’s what’s under the hood and what it means for drivers in the St. Peters and St. Charles area.

The Standard Engine: i-FORCE Turbocharged 4-Cylinder

The base powertrain is a 2.4-liter i-FORCE turbocharged four-cylinder producing 278 horsepower and 317 lb-ft of torque, paired with an 8-speed automatic transmission. For drivers who questioned whether a four-cylinder could replace a V6, the torque figure answers that concern directly. 317 lb-ft is more twist than the outgoing V6 produced, and it arrives lower in the rev range where everyday driving actually happens.

For St. Louis area drivers, that means confident highway merging on I-70, responsive passing on two-lane Missouri roads, and a powertrain that doesn’t feel strained when the vehicle is loaded up for a weekend trip. Towing capacity with this engine reaches up to 6,000 pounds when properly equipped. That’s enough for a bass boat, a utility trailer, or a small camper headed toward Lake of the Ozarks.

The Upgrade: i-FORCE MAX Hybrid System

Select trims, including the Platinum, TRD Pro, and Trailhunter, step up to the i-FORCE MAX hybrid system. This pairs the same 2.4-liter turbo engine with an electric motor integrated into the transmission for a combined output of 326 horsepower and 465 lb-ft of torque. That torque figure is the headline. It’s available almost instantly, which translates to effortless highway acceleration and, more importantly for off-road buyers, immediate low-speed pulling power on technical terrain.

Fuel economy improves meaningfully as well, with EPA estimates around 23 city and 24 highway, which is a real-world upgrade over what previous 4Runner drivers were accustomed to filling up for.

Off-Road Hardware: The Stabilizer Disconnect Mechanism

One of the more technically interesting additions to the new platform is the electronic Stabilizer Disconnect Mechanism available on TRD-grade trims. On standard road surfaces, the front sway bar operates normally to keep the vehicle flat and composed. When you engage it off-road, the system electronically disconnects the front stabilizer bar, allowing each wheel to travel more independently over uneven terrain. The result is dramatically improved suspension articulation on rocky or rutted trails without requiring any manual disconnection under the vehicle.

For Missouri drivers who explore the Ozark highlands or gravel roads through Mark Twain National Forest, it’s a genuine capability upgrade over the previous generation.
