What Is the Gas Mileage of the 2026 Toyota Tundra?
The 2026 Toyota Tundra earns an EPA-estimated 18 mpg city / 24 mpg highway / 20 mpg combined in the SR grade with rear-wheel drive — the highest EPA-estimated highway rating in the gas lineup. The SR5, Limited, Platinum, and 1794 Edition with rear-wheel drive are EPA-estimated at 18 mpg city / 23 mpg highway / 20 mpg combined. Every gas-powered Tundra with four-wheel drive is EPA-estimated at 17 mpg city / 22 mpg highway / 19 mpg combined.
EPA-estimated fuel economy figures are for comparison purposes only. Your actual mileage will vary depending on driving conditions, how you drive and maintain your vehicle, battery age/condition, and other factors.
Every gas Tundra uses the same 3.4-liter i-FORCE twin-turbo V6 with DOHC 24-valve cylinder heads and Dual VVT-i, offered in two states of tune. The SR produces 358 horsepower at 5,200 rpm and 406 lb-ft of torque at 2,000 rpm. The SR5, Limited, Platinum, and 1794 Edition step up to 389 horsepower and 479 lb-ft of torque.
For drivers who spend weekday mornings in stop-and-go freeway traffic through Irvine, these ratings set fair expectations for a full-size pickup that still has to work on the weekend. Toyota uses lightweight aluminum throughout the body, with high-strength steel where it is needed most. The available active aero front splitter deploys above 37 mph to modify airflow and cut drag at highway speeds.
What Is the EPA-Estimated MPG of the 2026 Toyota Tundra i-FORCE MAX Hybrid?
The 2026 Tundra i-FORCE MAX hybrid is EPA-estimated at 20 mpg city / 24 mpg highway / 22 mpg combined on the Limited, Platinum, and 1794 Edition with rear-wheel drive. With four-wheel drive, the Limited, Platinum, 1794 Edition, and Capstone are EPA-estimated at 19 mpg city / 22 mpg highway / 20 mpg combined. The TRD Pro, offered only with the i-FORCE MAX powertrain and four-wheel drive, is EPA-estimated at 18 mpg city / 20 mpg highway / 19 mpg combined — its off-road suspension and all-terrain tires account for the difference.
Toyota engineered i-FORCE MAX around output rather than maximum efficiency. The system combines the twin-turbo V6 with a motor generator and clutch located within the bell housing between the engine and the 10-speed automatic transmission, for a total of 437 horsepower at 5,200 rpm and 583 lb-ft of torque at 2,400 rpm. Power comes from a 288-volt sealed nickel-metal hydride battery mounted under the rear passenger seats. That low-end assist reduces how hard the gas engine has to work pulling away from a stop.
Shoppers on the lot usually ask whether the hybrid needs to be plugged in before they ask about fuel economy. It does not. Engine start-up, EV driving, electric assist, and energy regeneration are all handled by the parallel hybrid components, so the system keeps its own battery charged as you drive.
For weekend runs down to Huntington Beach with boards and gear in the bed, that instant throttle response is what most owners notice first. You can browse the new Tundra inventory at Tustin Toyota to see which powertrain is on the ground right now.

How Does the 10-Speed Automatic Transmission Affect Tundra Fuel Economy?
Both Tundra powertrains pair with a 10-speed Electronically Controlled Automatic Transmission with intelligence (ECT-i). It keeps the engine in its efficient range across a wide speed band. Ten closely spaced ratios cut the energy lost to wide gear jumps. The tall overdrive gears let the twin-turbo V6 hold highway speeds at low rpm, and that is the single biggest contributor to the Tundra’s EPA-estimated highway figures. The transmission also adds a sequential shift mode, uphill and downhill shift logic, and TOW/HAUL driving modes. Those modes adjust shift points under load rather than letting the truck hunt for gears.
Real-world fuel economy drops once you add a trailer, and how far it drops depends on trailer weight, frontal area, and terrain. For rated capacities by configuration, see our guide to the 2026 Toyota Tundra towing capacity.

How Far Can a 2026 Toyota Tundra Go on a Full Tank?
New for 2026, a 32.2-gallon fuel tank is standard on every Tundra grade. The smaller 22.5-gallon tank that used to come on lower trims is gone, so the SR now holds as much fuel as the Capstone.
The figures below multiply each configuration’s EPA-estimated combined rating by the 32.2-gallon capacity. They are calculated estimates, not a promise. Estimated range varies with payload, trailer weight, terrain, elevation change, ambient temperature, and driving habits. Steady highway speeds and tires kept at the pressures listed on the door-jamb label are what actually move the number in your favor.
2026 Toyota Tundra Estimated Range by Configuration
| Powertrain | Drivetrain | EPA-Estimated Combined MPG | Fuel Capacity | Estimated Range on a Full Tank |
|---|---|---|---|---|
| i-FORCE 3.4L twin-turbo V6 | Rear-wheel drive | 20 | 32.2 gallons | About 644 miles |
| i-FORCE 3.4L twin-turbo V6 | Four-wheel drive | 19 | 32.2 gallons | About 612 miles |
| i-FORCE MAX hybrid | Rear-wheel drive | 22 | 32.2 gallons | About 708 miles |
| i-FORCE MAX hybrid | Four-wheel drive | 20 | 32.2 gallons | About 644 miles |
| i-FORCE MAX hybrid, TRD Pro | Four-wheel drive | 19 | 32.2 gallons | About 612 miles |

Common Questions About 2026 Toyota Tundra Fuel Efficiency
Does the 2026 Toyota Tundra i-FORCE MAX hybrid require a plug-in charger?
No. The i-FORCE MAX is a self-charging hybrid and does not require a plug or a home charging station. Engine start-up, EV driving, electric assist, and energy regeneration are all handled by the parallel hybrid components, which keep the 288-volt nickel-metal hydride battery charged as you drive.
How does four-wheel drive affect the Tundra’s EPA-estimated gas mileage?
On gas-powered grades, four-wheel-drive configurations are EPA-estimated at 17 mpg city / 22 mpg highway, one to two mpg lower in each cycle than their rear-wheel-drive equivalents. On i-FORCE MAX hybrid grades, four-wheel-drive configurations are EPA-estimated at 19 mpg city / 22 mpg highway. The Tundra’s system is part-time four-wheel drive with an electronically controlled two-speed transfer case, not a full-time all-wheel-drive system.
What warranty coverage applies to the 2026 Toyota Tundra hybrid battery?
Toyota’s 2026 Tundra i-FORCE MAX Warranty & Maintenance Guide covers the hybrid battery for 10 years or 150,000 miles from the in-service date, whichever comes first. Hybrid system components — the hybrid battery control module, the hybrid control module, and the inverter with converter — carry 8 years or 100,000 miles. Basic coverage runs 36 months or 36,000 miles, and powertrain coverage runs 60 months or 60,000 miles.
