The Toyota 4Runner VI 2.4 i-FORCE, introduced in December 2024, represents the latest iteration of Toyota’s iconic SUV. This model year marks a significant shift for the 4Runner, moving to a turbocharged four-cylinder engine and continuing its reputation for off-road capability and rugged dependability. Positioned as a mid-to-upper trim level within the 4Runner VI range, the 2.4 i-FORCE with the ECT-i automatic transmission aims to balance performance with everyday usability. It builds upon the established foundation of the 4Runner, which has been a mainstay in the SUV market for decades, particularly in North America where body-on-frame construction remains highly valued.

INTRODUCTION
The 2024 Toyota 4Runner VI 2.4 i-FORCE represents a significant update to the popular SUV. Replacing the previous generation’s V6 engine, the 2.4-liter turbocharged four-cylinder engine (code T24A-FTS) delivers 278 horsepower and 430 lb-ft of torque. This engine is part of Toyota’s Dynamic Force engine family, known for its efficiency and responsiveness. The “ECT-i” designation refers to the 8-speed automatic transmission, designed to provide smooth shifting and optimized fuel economy. This variant is positioned as a strong all-around choice, appealing to buyers who want a balance of power, capability, and comfort. It slots in above the base model trims and below the more off-road focused TRD Pro models.
Powertrain & Engine Architecture
The heart of the 4Runner 2.4 i-FORCE is the T24A-FTS 2.4-liter inline-four engine. This engine utilizes a twin-scroll turbocharger and intercooler to boost power and efficiency. It features direct injection combined with multi-port fuel injection, optimizing combustion under various driving conditions. The engine also incorporates Toyota’s Dual VVT-i (Variable Valve Timing-intelligent) system, which adjusts valve timing on both the intake and exhaust sides for improved performance and fuel economy. The 8-speed automatic transmission (ECT-i) is designed for smooth and responsive shifting. It features electronically controlled torque converter lock-up and optimized gear ratios to maximize fuel efficiency and provide ample power for both on-road and off-road driving. The engine’s longitudinal mounting and rear-wheel-drive configuration contribute to the 4Runner’s traditional SUV feel and off-road prowess.
Driving Characteristics
The 2.4 i-FORCE powertrain delivers a noticeable improvement in performance compared to the previous V6 engine. The increased torque, available from as low as 1700 rpm, provides strong acceleration and effortless towing capability. The 8-speed automatic transmission contributes to a more refined driving experience, with smooth gear changes and a wider range of ratios. While not as overtly sporty as some competitors, the 4Runner 2.4 i-FORCE offers ample power for highway cruising and tackling challenging terrain. The rear-wheel-drive setup provides a traditional SUV feel, while available four-wheel-drive systems enhance off-road capability. Compared to manual transmission versions (if offered in other trims), the automatic prioritizes convenience and ease of use, making it ideal for daily commuting and long road trips.
Equipment & Trim Levels
The 2.4 i-FORCE trim typically includes a generous array of standard features. These often include Toyota Safety Sense 2.5, a suite of advanced driver-assistance systems, an 8-inch touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, and comfortable cloth upholstery. Higher sub-trims within the 2.4 i-FORCE range may add features such as leather upholstery, heated and ventilated front seats, a premium audio system, and a power moonroof. Optional extras can include a rear-seat entertainment system, upgraded off-road packages, and various exterior styling enhancements.
Chassis & Braking
The 4Runner VI maintains a traditional body-on-frame construction, providing robust durability and off-road capability. The suspension system consists of a coil spring, double wishbone setup at the front and a rigid axle suspension with coil springs and a transverse stabilizer bar at the rear. This configuration balances ride comfort with off-road articulation. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power. The 4Runner’s ABS (Anti-lock Braking System) enhances safety by preventing wheel lockup during hard braking. Steering is rack-and-pinion with electric power assist, offering precise control and a comfortable driving experience.
Market Reception & Comparison
The introduction of the 2.4 i-FORCE engine has been generally well-received by automotive critics. The engine’s improved fuel economy and increased torque have been praised, as has the smooth operation of the 8-speed automatic transmission. Compared to the previous V6 engine, the 2.4 i-FORCE offers a more refined and efficient driving experience. In terms of fuel economy, the 4Runner 2.4 i-FORCE achieves around 22 mpg combined, which is competitive within its class, though not class-leading. Reliability is expected to be high, consistent with Toyota’s reputation for building durable vehicles. Compared to other trims in the 4Runner lineup, the 2.4 i-FORCE offers a compelling balance of performance, features, and price.
Legacy
The T24A-FTS engine and the 8-speed automatic transmission are relatively new to the 4Runner lineup, so long-term reliability data is still emerging. However, Toyota’s Dynamic Force engines have proven to be durable in other applications. The 4Runner’s body-on-frame construction and robust drivetrain are known for their longevity. On the used car market, the 2024 4Runner 2.4 i-FORCE is expected to hold its value well, given the model’s strong reputation and enduring popularity. The combination of modern technology and traditional SUV attributes positions this variant as a desirable choice for buyers seeking a capable and reliable vehicle for years to come.
