The 2015 Toyota Tundra 4WD FFV with the 5.7L V8 gets 15 MPG combined. This number might discourage some, but Tundra owners understand it’s the cost for serious towing, hauling, and off-road performance. This truck prioritizes strength and reliability over fuel efficiency.

City and highway performance

The EPA estimates the Tundra at 13 MPG in the city and 17 MPG on the highway. The city MPG reflects stop-and-go driving. The Tundra performs a little better on the highway, but the aerodynamics, which prioritize payload over reducing air resistance, limit fuel efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Toyota Tundra 4WD FFV 5.7L at $2,900. This is based on driving 15,000 miles per year using a national average fuel price. Individual costs will vary depending on driving habits and local fuel prices. Consider this benchmark when budgeting for Tundra ownership.

Real-world expectations

Real-world MPG can vary from EPA estimates. Expect lower numbers if you frequently tow heavy loads. If you use the Tundra as a daily driver and drive gently, you might approach the EPA highway rating. But remember physics, especially with a large, heavy vehicle.

How it compares

The 2015 Tundra’s fuel economy is average for its class. A 2015 Ford F-150 4×4 with the 5.0L V8 gets about 17 MPG combined, slightly better than the Tundra. A 2015 Chevrolet Silverado 1500 4×4 with the 5.3L V8 also gets around 17 MPG combined. While these trucks offer slightly better MPG, Tundra buyers often choose it for Toyota’s reliability and strong resale value, which can be more important than fuel savings.

Tips to maximize efficiency

Use a smart driving strategy to save fuel in your Tundra. Avoid quick acceleration and hard braking, as they waste fuel. Maintain a steady speed on the highway, which is more efficient than changing your speed often.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, which makes the engine work harder and use more fuel. Check your tire pressure regularly and inflate them to the recommended level on the door jamb sticker. This helps with fuel efficiency and extends tire life. You can also consider low rolling resistance (LRR) tires when replacing your current tires.

Remove extra weight from the truck bed or cab. Added weight increases the engine’s workload decreasing fuel economy. Take out any tools, equipment, or cargo that you don’t regularly need. Weight reduction can save fuel.

Use cruise control on flat highways. Cruise control helps maintain a consistent speed, reducing unnecessary acceleration and deceleration. Disable cruise control on hills, as the system may downshift to maintain speed, canceling fuel savings. Explore TUNDRA MPG across all years to come to your own conclusions.

Maintain your vehicle well. Regular servicing, including oil changes, air filter replacements, and spark plug maintenance, helps your engine run efficiently. A neglected engine will deliver worse fuel economy than a well-maintained one. A clean air filter is particularly important if you drive in dusty conditions, even without off-roading.
