By the end, you’ll know which truck offers the best gas mileage for your needs and how to keep your fuel budget in check.
How 2024 Truck Models Achieve Superior Fuel Efficiency
1. Hybrid Powertrains and Mild Hybrid Systems
Hybrid technology marries an internal combustion engine with an electric motor. Mild hybrids use a small electric assist to reduce engine load, boosting mpg without the complexity of full hybrids.
In 2024, several trucks feature 48‑volt mild hybrid systems that shave 2–3 mpg off traditional models. The electric motor takes over at idle and during low‑speed driving, reducing fuel burn.
2. Advanced Turbocharging and Direct Injection
Turbocharging forces more air into the engine, enabling smaller displacements while maintaining power. When paired with direct injection, fuel is sprayed precisely into the combustion chamber, enhancing combustion efficiency.
Modern turbocharged engines achieve 20–25% better fuel economy than larger naturally aspirated counterparts.
3. Lightweight Materials and Aerodynamic Design
Replacing steel with aluminum or composite parts cuts weight, lowering fuel consumption. Rounded hoods, split rear windows, and active grille shutters reduce drag.
Some trucks now feature aerodynamic skirts that streamline airflow, adding up to 0.5 mpg on long highway trips.
4. Low‑Rolling‑Resistance Tires and Efficient Drivetrains
Tires with low rolling resistance reduce the energy needed to keep the vehicle moving. Coupled with 9‑speed automatic transmissions that shift at optimal RPMs, these trucks maintain fuel efficiency across all driving conditions.
Manufacturers also offer selectable drive modes—Eco, Normal, and Performance—allowing drivers to toggle the engine’s torque curve for maximum savings.
Top 5 Trucks with the Best Gas Mileage in 2024
1. Ford F‑150 PowerBoost™ Hybrid
The F‑150 PowerBoost™ Hybrid combines a 3.0L V6 engine with a 30‑kW electric motor, delivering 21 mpg city and 24 mpg highway. Its 12.6‑kWh battery powers the motor for short bursts, improving acceleration while saving fuel.
Key features include an integrated regenerative braking system and an Eco mode that limits engine output during light load.
2. Ram 1500 eTorque™ Mild Hybrid
The Ram 1500’s eTorque system uses a 48‑volt electric motor to assist the 3.6L V6. Official EPA ratings show 20 mpg city and 23 mpg highway, a noticeable lift over the standard model.
Its “Eco” drive mode also reduces air conditioning output to conserve energy.
3. Chevrolet Silverado 1500 EcoDiesel®
The EcoDiesel® 2.7L turbo‑diesel engine delivers 22 mpg city and 25 mpg highway—exceptional for a truck that can tow 13,200 lbs. The diesel’s high torque at low revs improves fuel economy under load.
Features include a variable‑geometry turbocharger and a three‑stage exhaust system to reduce emissions.
4. Toyota Tundra Hybrid
Toyota’s first hybrid Tundra pairs a 5.7L V8 with a 15‑kW electric motor, achieving 18 mpg city and 21 mpg highway. The hybrid’s regenerative braking recovers energy that would otherwise be lost.
It also offers a 20‑year/200,000‑mile powertrain warranty, boosting confidence in its longevity.
5. Nissan Frontier Limited (2.5L Turbo)
The 2024 Frontier Limited features a 2.5L turbocharged inline‑4 engine that delivers 20 mpg city and 23 mpg highway. Its small displacement and turbocharging yield a perfect balance of power and economy.
The truck’s “Eco” mode limits the engine’s torque peak, shaving extra fuel off daily commutes.

Pro Tips for Maximizing Fuel Mileage on Your Truck
- Use Eco Drive Mode—Engage Eco or Eco+ modes to limit engine power and reduce air conditioning use.
- Maintain Optimal Tire Pressure—Check tire pressure monthly; under‑inflated tires increase rolling resistance.
- Plan Efficient Routes—Use GPS apps that suggest the most fuel‑efficient paths, avoiding heavy traffic and stop‑and‑go driving.
- Keep Your Truck Light—Remove unnecessary cargo; every pound adds drag and fuel cost.
- Use Cruise Control on Highways—Maintains a steady speed, preventing unnecessary acceleration.
- Service Regularly—Change oil, air filters, and spark plugs as recommended to keep the engine running efficiently.
- Use the Right Fuel—Use the octane rating the manufacturer recommends; higher octane does not mean better mileage.
- Limit Fast Acceleration—Accelerate gently; rapid bursts use more fuel.
- Park in Shade or Use a Sunshade—Reducing cabin heat cuts the need for air conditioning.
- Consider a Front‑Wheel‑Drive Trim—If you don’t need 4WD, choose FWD to save weight and improve economy.
Frequently Asked Questions about best gas mileage trucks
What is the most fuel‑efficient truck for towing?
The Chevrolet Silverado 1500 EcoDiesel® offers the best highway mileage while still towing over 13,000 lbs, thanks to its high‑torque diesel engine.
Are hybrid trucks worth the extra cost?
Hybrid trucks often come with a higher purchase price, but fuel savings over time can offset the upfront cost, especially if you drive long distances.
How does a mild hybrid differ from a full hybrid?
A mild hybrid uses a small electric motor to assist the engine; it doesn’t power the vehicle alone. A full hybrid can drive solely on electric power for short distances.
Can I use regular gasoline in a diesel truck?
No. Diesel engines require diesel fuel. Using gasoline can damage the engine and reduce performance.
Do all trucks now come with an Eco mode?
Most new trucks have an Eco mode, but the level of control varies by manufacturer. Check the vehicle’s manual for details.
What tires are best for fuel efficiency?
Low‑rolling‑resistance tires made from softer rubber compounds reduce drag and improve mpg. Look for tires labeled “fuel‑saving” or “eco‑friendly.”
How often should I rotate my tires?
Rotate tires every 5,000–7,000 miles to ensure even wear and maintain optimal fuel efficiency.
Does towing affect fuel mileage significantly?
Yes. Towing increases weight and drag, reducing mpg. Use the truck’s Eco mode to minimize impact during light towing.
Should I keep my truck’s doors open while driving?
No. Open doors create aerodynamic drag, lowering fuel economy. Keep doors closed for best mileage.
Is it better to drive at higher speeds to save fuel?
No. Fuel efficiency typically peaks around 55–65 mph. Driving significantly faster increases drag and fuel use.
In summary, the modern truck landscape offers a range of fuel‑efficient options, from hybrid powertrains to advanced diesel engines. By selecting the right model and following proven driving habits, you can enjoy the versatility of a truck without the burden of high fuel costs.
