How many miles per gallon does a 3.5 Tundra get?
The 3.5-liter i-FORCE twin-turbo V6 in the Toyota Tundra typically achieves about 19–21 mpg combined across common configurations, with highway mileage often higher and city driving lower. Actual mileage varies by drivetrain, cab/bed setup, and how the truck is used.
This article explains the official EPA estimates for different setups, what factors influence real-world results, and tips for maximizing efficiency. Numbers below reflect recent model years (2023–2025) and can vary by year and equipment package. Always check the latest EPA ratings for your exact configuration.
EPA estimates by configuration
The EPA publishes city/highway/combined fuel economy estimates for the Tundra’s various configurations. The numbers differ depending on whether the truck is two-wheel drive or four-wheel drive, and whether it uses the CrewMax (5.5-foot bed) or Access Cab (6.5-foot bed). Below are representative figures from recent model years.
- 2WD CrewMax with 5.5-foot bed: 19 mpg city / 23 mpg highway / 21 mpg combined
- 4WD CrewMax with 5.5-foot bed: 18 mpg city / 22 mpg highway / 20 mpg combined
- 2WD Access Cab with 6.5-foot bed: 19 mpg city / 23 mpg highway / 21 mpg combined
- 4WD Access Cab with 6.5-foot bed: 18 mpg city / 22 mpg highway / 19–20 mpg combined
These figures assume the standard equipment and a 10-speed automatic transmission, under EPA testing procedures. Real-world mileage can differ based on payload, towing, terrain, and driving style.
What factors affect real-world MPG?
Even with EPA estimates as a baseline, several variables can shift actual fuel economy for the Tundra. The following factors are commonly cited by owners and reviewers as having the biggest impact on mpg in day-to-day driving.
- Payload and towing: Heavy loads sap efficiency, especially during acceleration and climbs.
- Terrain and driving style: Stop-and-go city driving lowers mpg more than steady highway speeds.
- Aerodynamics and accessories: Bed covers, racks, and aftermarket gear can increase drag and reduce efficiency.
- Maintenance and fuel quality: Proper tire pressure, regular maintenance, and quality fuel help sustain mpg.
- Environmental conditions: Temperature, elevation, wind, and humidity influence performance and fuel use.
To maximize efficiency, keep tires inflated to recommended pressures, use cruise control on highways when appropriate, and plan trips to minimize unnecessary idling and stops.
Summary
The 3.5-liter i-FORCE twin-turbo V6 in the Toyota Tundra delivers roughly 19–21 mpg combined in typical configurations, with 2WD setups generally edging out 4WD models. Highway mileage tends to be higher, around the low to mid-20s for 2WD configurations, while 4WD variants sit in the low to mid-20s on the highway. Always verify the exact EPA rating for your specific configuration and consider real-world factors when estimating fuel costs for a given truck.
