The 2024 Toyota Tacoma 4WD equipped with the i-FORCE 2.4L turbocharged engine delivers an EPA-estimated 19 mpg city, 23-24 mpg highway, and 20-21 mpg combined, depending on the trim and transmission. The 2025 updates focused on expanding the i-FORCE MAX hybrid availability and refining interior technology across the lineup.
Understanding the Shift: The N400 Generation Powertrains
With the launch of the fourth-generation "N400" Tacoma in 2024, Toyota retired the long-standing 3.5-liter V6 in favor of a more efficient and torque-rich 2.4-liter turbocharged four-cylinder engine. This transition was driven by a need to meet stricter emissions standards while providing the low-end torque required for off-roading and towing. As we look back from 2026, it is clear that this move redefined the mid-size truck segment's expectations for fuel economy.
The 2024 model year introduced two primary versions of this powertrain: the standard i-FORCE and the high-output i-FORCE MAX hybrid. For 4WD enthusiasts, the distinction between these two is critical, as the hybrid system was specifically engineered to supplement power rather than just optimize fuel savings. This means that while 4WD models saw an improvement over the previous V6 generation, the gains were balanced against significant increases in horsepower and torque.
The Standard i-FORCE 2.4L Turbo
In the 2024 4WD models, the standard i-FORCE engine is tuned differently depending on the trim. In the entry-level SR 4WD, it produces 228 horsepower, while higher trims like the SR5, TRD Sport, and TRD Off-Road see an increase to 278 horsepower. The fuel economy remains relatively consistent across these outputs, though the physical configuration of the truck—such as tire size and aerodynamic aids—plays a larger role in the final MPG figures.
The i-FORCE MAX Hybrid
The i-FORCE MAX, which became more widely available during the 2025 model year rollout, pairs the 2.4L engine with a 48-hp electric motor integrated into the 8-speed transmission. This setup produces a staggering 326 horsepower and 465 lb-ft of torque. For 4WD users, this powertrain offers the best fuel economy in the lineup, particularly in stop-and-go city driving where the electric motor can assist in moving the truck's mass.
2024 Tacoma 4WD MPG Breakdown by Trim and Transmission
Fuel efficiency for the 2024 Tacoma 4WD is not a monolithic number. It varies based on whether the vehicle is equipped with the 8-speed automatic transmission or the 6-speed intelligent Manual Transmission (iMT2), as well as the specific aerodynamic profile of the trim level.
Automatic Transmission 4WD Figures
The majority of 2024 Tacomas on the road today feature the 8-speed automatic. This transmission is programmed to keep the turbocharged engine in its optimal power band while maximizing fuel economy during highway cruising.
- SR 4WD (Automatic): 19 City / 23 Highway / 21 Combined
- SR5 & TRD Sport 4WD (Automatic): 19 City / 24 Highway / 21 Combined
- TRD Off-Road 4WD (Automatic): 19 City / 23 Highway / 20 Combined
The slight dip in the TRD Off-Road’s highway figure is primarily attributed to its all-terrain tires and the omission of the front air dam, which is included on the SR5 and TRD Sport to improve airflow.
Manual Transmission 4WD Figures
Toyota remained one of the few manufacturers to offer a manual transmission in 2024. However, choosing the three-pedal setup comes with a fuel economy penalty. The manual transmission lacks the tall overdrive gears found in the 8-speed automatic, leading to higher RPMs at highway speeds.

The Impact of 4WD Systems on Efficiency
The 2024 Tacoma utilizes two different 4WD systems that impact fuel consumption differently. Most trims use a part-time 4WD system with a two-speed electronically controlled transfer case. Under normal driving conditions on dry pavement, the truck operates in RWD (2WD High), which disconnects the front driveline to reduce mechanical drag and improve MPG.
In contrast, the 2024 and 2025 Limited and higher-tier i-FORCE MAX trims often feature a full-time 4WD system with a center locking differential. While this provides superior traction on variable surfaces, the constant engagement of the front drivetrain components creates slightly more parasitic loss. However, Toyota's engineering on the TNGA-F platform has minimized this gap, allowing the hybrid Limited models to maintain a combined 23 MPG despite the full-time 4WD configuration.
2025 Model Year Updates: What Changed?
The 2025 Toyota Tacoma did not reinvent the wheel but rather completed the vision started in 2024. By the time the 2025 models hit showrooms, the supply chain for the i-FORCE MAX hybrid components had stabilized, leading to a much broader availability of the hybrid powertrain.
Expansion of the i-FORCE MAX
In 2024, the hybrid powertrain was largely reserved for the highest trims (TRD Pro and Trailhunter). For 2025, Toyota made the i-FORCE MAX an available option on the TRD Off-Road and TRD Sport trims. This allowed buyers to opt for the higher torque and improved city fuel economy without having to step up to the flagship off-road models.
Introduction of New Trim Features
The 2025 updates included minor but significant equipment changes:
- Standard Power Tailgate: Previously an option on mid-tier trims, the power open/close tailgate became more common in 2025 packages.
- Enhanced Digital Displays: The 14-inch Toyota Audio Multimedia touchscreen, which was a standout feature in 2024, became standard on more 4WD configurations in 2025.
- Trailhunter Refinements: The 2025 Trailhunter trim, designed specifically for overlanding, received updated suspension tuning to handle the weight of aftermarket armor and roof racks more efficiently, which indirectly helps maintain fuel economy when the truck is fully loaded.
Rear Seat Removals
One notable "hidden" update in the 2025 4WD SR models was the expanded availability of the XtraCab configuration. By removing the rear seats and focusing on utility storage, this configuration reduced the vehicle's curb weight, slightly improving real-world responsiveness, even if the EPA ratings remained static.
Real-World Considerations for 4WD Fuel Economy
While EPA figures provide a baseline, 4WD Tacoma owners often experience different results based on how they use their trucks. The N400 generation is highly sensitive to modifications and driving habits.
The "Lift and Tire" Tax
The 2024 and 2025 Tacomas are designed with specific aerodynamic profiles. Adding a 2-inch lift kit and 33-inch or 35-inch mud-terrain tires—a common modification for TRD Off-Road owners—can result in a 2 to 4 MPG drop on the highway. The increased rolling resistance and the disruption of airflow under the vehicle are the primary culprits.
Payload and Towing
The turbocharged 2.4L engine is highly efficient when cruising, but the turbocharger works harder under load. When towing near the 6,500-lb limit or carrying a heavy camper shell, the fuel economy will drop more significantly than it did in the old naturally aspirated V6. Users have reported highway figures as low as 12-14 MPG when towing large trailers, which is typical for small-displacement turbocharged engines under high stress.
Winter Driving and Fuel Blends
In colder climates, the 4WD system is engaged more frequently. Additionally, "winter blend" gasoline contains less energy per gallon than summer blends. 2024 Tacoma owners in northern regions may see a seasonal drop of 10-15% in their fuel efficiency during the winter months.
Maintenance and Long-Term Efficiency
As of 2026, many 2024 Tacomas have surpassed the 30,000-mile mark. Maintaining the fuel economy figures mentioned above requires adherence to Toyota’s specific maintenance schedule for the turbocharged platform.
- Air Filter Consistency: Turbocharged engines require high volumes of clean air. A clogged engine air filter will cause the ECU to adjust fuel mapping, often leading to increased consumption.
- Driveline Fluids: For 4WD models, changing the differential fluid and transfer case fluid according to the "Special Operating Conditions" schedule (especially if towing or off-roading) ensures that mechanical friction is kept to a minimum.
- Tire Pressure: The 2024 Tacoma features a sophisticated Tire Pressure Monitoring System (TPMS). Keeping tires at the door-jamb recommended PSI is the simplest way to maintain the 23-24 highway MPG rating.
Frequently Asked Questions
Does the 2024 Tacoma 4WD require premium fuel to get the best MPG?
No, the 2024 Toyota Tacoma is designed to run on 87-octane regular unleaded gasoline. While some turbocharged engines benefit from higher octane to prevent pre-detonation under high heat, Toyota’s engineering allows for full power and rated fuel economy using standard fuel. Using premium will not significantly increase your MPG.
How does the 2024 Tacoma 4WD MPG compare to the Ford Ranger?
The 2024 Tacoma 4WD is highly competitive. The Ford Ranger 4WD (2.3L EcoBoost) typically sees 20 city / 24 highway, which is nearly identical to the Tacoma SR5 4WD. The Tacoma’s advantage lies in the i-FORCE MAX hybrid option, which offers higher torque than the standard Ranger engines while maintaining superior city fuel economy.
Why is my 2024 Tacoma TRD Off-Road getting lower MPG than the SR5?
The TRD Off-Road lacks the large plastic front air dam found on the SR5 and TRD Sport. This air dam is designed to redirect air around the truck rather than under the turbulent chassis. While removing it improves the approach angle for off-roading, it increases aerodynamic drag at speeds over 45 mph, leading to a 1-2 MPG decrease on the highway.
Was there a fuel tank size increase in the 2025 model?
No, the fuel tank capacity remained the same for 2025. Standard i-FORCE models typically feature an 18.2-gallon tank. While this is smaller than some full-size trucks, the improved efficiency of the 2.4L engine provides a total cruising range that is comparable to the previous generation with its larger tank.
Does the 2025 i-FORCE MAX hybrid require more maintenance than the 2024 standard engine?
The hybrid system is largely maintenance-free for the first several years. The NiMH (Nickel-Metal Hydride) battery is designed for the life of the vehicle, and the electric motor is integrated into the transmission. The primary difference is the cooling system for the hybrid battery, which has an air filter that should be checked periodically to ensure the battery stays at its optimal operating temperature.
Final Recommendation for Buyers and Owners
If your primary goal is maximizing fuel economy in a 4WD Tacoma, the 2025 SR5 or TRD Sport with the i-FORCE MAX hybrid is the optimal choice. It provides the best balance of city efficiency and highway cruising capability. For those who own a 2024 model with the standard i-FORCE engine, maintaining factory tire sizes and keeping the front air dam installed (if your trim includes it) are the most effective ways to hit the EPA-estimated 24 MPG highway figure. As the N400 generation matures, it continues to prove that moving to small-displacement turbocharged power was a necessary and successful evolution for the Tacoma brand.
