Indeed, a tonneau cover can increase gas mileage, yet the key is to control several elements. A truck without a tonneau cover accelerates and collects air, which generates resistance and slows the vehicle down. This fuels the engine's greater burning.
Part 1- Does a Tonneau Cover Improve Gas Mileage?
Yes, a tonneau cover can improve gas mileage by reducing wind resistance and drag.
- Reducing Drag: Seals the truck bed to minimize air turbulence.
- Improving Aerodynamics: Streamlined covers decrease wind resistance.
- Assisting Acceleration: Less drag helps the truck accelerate more efficiently, reducing fuel loss.
However, the primary savings are mainly based on the cover type, truck model, and driving conditions.
Let’s first explore how a tonneau cover improves fuel economy for you.
Part 2. How Does a Tonneau Cover Improve Gas Mileage? Detailed Guide
Improving aerodynamics and lowering drag help a tonneau cover maximize gas mileage. The cover closes the bed so that air passes over the truck without disruption.
The amount of fuel saved varies depending on factors such as the truck model, driving speed, and type of cover. The following are the features of the tonneau cover that support fuel economy.
Reducing Drag
Drag is the force air resistance causes to slow down your truck. Air traps inside the open truck bed and generates turbulence. This increases the drag coefficient (Cd), which propels the engine to run on more gasoline to maintain speed.
Reducing this effect, a tonneau cover produces a smooth surface over the truck bed. Studies show that a tonneau cover can lower drag by up to 5%, which might cause a 2% rise in fuel economy.
Although this might not seem like much, over time, the savings grow, particularly for frequent highway users.
Hard tonneau covers provide better aerodynamics than soft covers, making them the best fuel-efficient option.
Improving Aerodynamics
Aerodynamics is the movement of air around a vehicle. Although trucks are built to cut through the wind effectively, an open bed disturbs this airflow. Air becomes stuck in the bed instead of moving quickly over the truck, producing a vortex effect that slows the truck down.
A tonneau cover can remove this disturbance by covering the bed. This allows air to flow naturally from the front to the rear, saving fuel to keep the truck moving quickly. Under ideal circumstances, some tests have even noted gas mileage increases up to 10%.
Fact:
A sleek, retractable hard tonneau cover like the Mountain Top EVO-M is one of the best options for maximizing aerodynamic benefits.
Helping with Acceleration
Accelerating from a stop wastes most fuel. Acceleration is less effective in a truck without a tonneau cover since it faces more air resistance. The engine lessens its effort to attain highway speeds when drag is lowered.
Soft rolling-up and soft folding covers are especially helpful in this sense. Their weightlessness helps the truck not gain further weight. This keeps the vehicle light for best fuel economy while lowering drag.
Because of their weight, heavy hard-shell covers can occasionally lower the aerodynamic advantage; hence, selecting the appropriate tonneau cover is quite important.
Before you invest in a tonneau cover, consider the following key factors to maximize fuel savings and efficiency.
Part 3. What are the Truck Fuel Saving Considerations with Tonneau Cover?
Though the savings rely on several elements, a tonneau cover can help increase fuel economy. Fuel savings depend on the kind of cover, driving style, and state of the roads.
Let's closely investigate these elements.
Type of Cover and Its Role in Fuel Efficiency
Not every tonneau cover provides the same degree of fuel savings. How effectively a cover lowers drag and enhances aerodynamics depends on the materials, design, and fit.
1. Lightweight Soft Covers for Moderate Fuel Savings
Vinyl or cloth stretched over a lightweight frame makes soft tonneau covers. They offer basic aerodynamics, but they might not produce a totally sealed truck bed, therefore causing some airflow disturbance.
- Truck owners who need complete bed access will find soft covers perfect since they are easy to install and remove.
- They are usually more reasonably priced and offer a cheap way to raise fuel economy.
-
Designed to cut drag, but it might not match hard cover fuel savings.
2. Hard Covers for Maximum Aerodynamic Benefits
Hard tonneau covers are made of aluminum, fiberglass, or polycarbonate. These covers offer the highest aerodynamics and durability.
- Their stiff construction seals tightly, preventing airflow disturbance in the truck bed.
- Hard covers are more secure and provide additional protection against theft and harsh weather conditions.
- Certain premium types, such as one-piece and retractable coverings, are made especially to improve fuel savings.
Fact:
According to a study by the Specialty Equipment Market Association (SEMA), hard tonneau covers can improve fuel efficiency by up to 10% in ideal conditions.
Which One is Best?
Soft and hard covers have benefits, but if fuel efficiency is your top priority, a hard tonneau cover is the better choice. Below is a comparison to help you decide.
| Features | Soft Tonneau Cover | Hard Tonneau Cover |
|---|---|---|
| Aerodynamics | Moderate | Maximum improvement |
| Fuel Savings | Up to 3-5% | Up to 10% |
| Weight | Lightweight | Heavier |
| Durability | Less durable | Highly durable |
| Security | Basic protection | Strong security against theft |
| Cost | Budget-friendly | Expensive |
| Best For | Occasional highway drivers | Frequent highway drivers and fuel-conscious users |
A hard-folding tonneau cover can be a better option if you want to strike the best balance between cost and efficiency.
Driving Conditions and Their Influence on Fuel Savings
Your driving environment greatly impacts the effectiveness of a tonneau cover in improving gas mileage.
Highway Driving
A tonneau cover can provide most of the fuel savings on highways, where high speeds create the highest drag. A U.S. Department of Energy study found that reducing drag can increase highway fuel economy by up to 10%.
City Driving
Crowded roads in the city with heavy traffic reduce the aerodynamic benefits of a tonneau cover, leading to lower fuel savings.
Windy Conditions
A well-sealed hard cover is the best option for drivers who frequently drive in strong winds. It prevents air from getting trapped in the truck bed, reducing instability.
Hilly Terrain
Tonneau covers offer little to no fuel savings in uphill driving, as gravity plays a greater role in fuel consumption.
Fact:
Trucks without a tonneau cover experience a 12-15% increase in fuel consumption when driving against strong winds.
Before buying a tonneau cover, consider the below-mentioned key factors to maximize fuel savings.

Tonneau covers are investments that affect fuel economy and security. To get the greatest deal, consider these considerations before buying.
Cost Factor
A tonneau cover can be expensive but saves fuel and protects your truck bed. The cost varies depending on the material, design, and brand. Different types of covers include
- Soft Covers: Budget-friendly but may not provide the best fuel savings.
- Hard Covers: These are more expensive but offer better aerodynamics and security.
- Retractable Covers: A premium option with excellent convenience and fuel efficiency.
If you drive long distances frequently, investing in a hard cover may save more fuel, making up for its higher price over time.

Sealing and Maintenance
When one lets a poorly sealed tonneau cover in water, dust, and trash, its efficiency suffers. Good performance and lifetime depend on regular maintenance. To ensure best maintenance, you need to
- Check for Gaps: A properly sealed cover prevents wind resistance and keeps cargo safe.
- Clean Regularly: Dust and dirt can damage soft covers over time.
- Lubricate Moving Parts: Retractable covers need regular lubrication for smooth operation.
Fact: Depending on the material, a well-maintained tonneau cover lasts 5-10 years.
Cargo Space Limitations
Not all tonneau covers allow full bed access, and some are more flexible than others. The following are the different types of covers and their modes of ease.
- Soft Roll-Up Covers: Easy to remove, providing full access when needed.
- Hard Folding Covers: Partially open but limited to large cargo space.
- Retractable Covers: Offer a balance between security and accessibility.
A roll-up or retractable cover is preferable for carrying large things.
