Does A Truck Bed Cover Improve Gas Mileage?
Remember that last road trip? You packed everything you could think of in your truck bed, and suddenly your gas mileage seemed to plummet. This got you thinking: Does a truck bed cover actually help with gas mileage? This article explores that very question, providing you with the facts, figures, and expert insights to help you decide if a truck bed cover is a worthwhile investment for your fuel efficiency. You’ll discover how much you could save and what factors influence the impact on your fuel economy.
Aerodynamics and Fuel Efficiency
The primary way a truck bed cover affects gas mileage is through aerodynamics. A cover significantly reduces wind resistance, also known as drag. This reduction translates directly to better fuel economy, as the truck doesn’t have to work as hard to push through the air.
Drag Reduction
- A smooth, well-fitting truck bed cover minimizes turbulence behind the truck, reducing aerodynamic drag. This is especially noticeable at higher speeds where air resistance is a major factor in fuel consumption. A properly installed cover can significantly decrease the amount of air that is slowed and churned up behind the truck bed.
- The shape and material of the cover influence drag reduction. Hard tonneau covers tend to offer slightly better aerodynamics than soft covers, especially at higher speeds, due to their more streamlined design. However, even soft covers offer a notable improvement over an open truck bed.
- The exact amount of drag reduction varies depending on factors like the type of cover, truck model, and driving conditions. However, studies have shown that even modest reductions in drag can lead to measurable improvements in fuel efficiency.
Wind Resistance and Fuel Consumption
Wind resistance is a substantial factor impacting fuel consumption, especially at highway speeds. A study conducted by the Department of Energy found that 25% of a vehicle’s fuel consumption can be attributed to wind resistance at speeds exceeding 40 mph. A truck bed cover helps to significantly reduce this percentage, resulting in notable fuel savings over time.
Types of Truck Bed Covers and Their Impact
Different types of truck bed covers offer varying degrees of aerodynamic improvement. This section compares the gas mileage benefits offered by various truck bed cover styles.
Hard Tonneau Covers
- Hard tonneau covers often provide superior aerodynamics due to their smooth, solid surfaces. They usually result in the most significant improvements in fuel economy compared to soft covers or an open bed.
- The seamless design minimizes gaps and reduces air turbulence, leading to improved airflow around the truck bed. This contributes directly to lower drag and higher fuel efficiency.
- However, hard covers are usually more expensive than soft covers and can be more challenging to install.
Soft Tonneau Covers
- Soft tonneau covers provide a good balance between cost and aerodynamic benefits. While not as aerodynamic as hard covers, they still significantly reduce drag compared to an open truck bed.
- The flexible material allows for some adaptation to airflow, which can be beneficial in certain conditions. However, it might not be as effective in reducing wind resistance as a rigid cover.
- Soft covers are usually easier to install and remove than hard covers, offering greater flexibility.
Roll-Up Covers
- Roll-up covers offer a compromise between convenience and aerodynamics. When fully retracted, they offer little aerodynamic benefit, while fully extended they show moderate improvements in gas mileage.
- Their design means a slightly larger profile compared to hard or soft covers, which can affect fuel efficiency. While they offer good protection from the elements, their impact on gas mileage is less than hard tonneau covers.
- They provide flexibility, allowing the user to adjust the coverage depending on the need, offering a balance between cargo security and fuel efficiency.
Factors Affecting Fuel Efficiency Beyond the Cover
While a truck bed cover can significantly contribute to better gas mileage, several other factors play a crucial role. Understanding these factors allows you to optimize your fuel economy even further.
Driving Habits
- Aggressive acceleration and braking significantly impact fuel efficiency. Smooth, consistent driving minimizes fuel consumption regardless of the truck bed cover.
- Maintaining a consistent speed, especially on highways, helps reduce drag and improve gas mileage. Avoid frequent speed changes as this impacts fuel consumption.
- Proper tire inflation is crucial. Under-inflated tires increase rolling resistance, reducing fuel economy. Always maintain the recommended tire pressure for your vehicle.
Vehicle Maintenance
- Regular vehicle maintenance, including engine tune-ups and oil changes, ensures optimal engine performance and fuel efficiency.
- A well-maintained vehicle runs more smoothly, reducing unnecessary fuel consumption. This includes regular checks on filters, spark plugs, and other vital parts.
- Ignoring maintenance can lead to increased fuel consumption and potentially more costly repairs in the long run.
Cargo Weight
- Carrying excessive weight in the truck bed significantly reduces gas mileage. Even with a cover, additional weight increases fuel consumption.
- Minimize unnecessary cargo whenever possible. Optimize cargo placement for better weight distribution, improving handling and fuel efficiency.
- Properly securing cargo is also important to reduce drag and prevent damage, further increasing fuel efficiency.
Real-World Examples and Case Studies
Let’s look at some real-world examples illustrating the impact of a truck bed cover on gas mileage.
- A study by Edmunds.com showed a 7% improvement in fuel economy for a pickup truck equipped with a hard tonneau cover compared to the same truck with an open bed.
- In another instance, a truck owner reported a 5% increase in gas mileage after installing a soft tonneau cover on their vehicle. This improvement was particularly noticeable during long highway drives.

Debunking Common Myths About Truck Bed Covers
Myth 1: All truck bed covers offer the same gas mileage improvement.
This is false. The type of cover (hard, soft, roll-up) significantly impacts its aerodynamic performance and, consequently, the improvement in gas mileage. Hard tonneau covers generally offer the best results, while roll-up covers have the least impact.
Myth 2: A truck bed cover only affects gas mileage at high speeds.
While the impact is more significant at higher speeds, a truck bed cover still improves gas mileage at lower speeds due to reduced wind resistance and turbulence even at low speeds, although the improvement is less noticeable than at higher speeds.
Myth 3: The gas mileage improvement from a truck bed cover isn’t worth the cost.
This depends on individual circumstances. While the initial cost of a truck bed cover may seem significant, the long-term savings in fuel costs can offset the investment, especially for those who frequently drive long distances.
FAQ
Does a truck bed cover really make a difference in fuel efficiency?
Yes, a truck bed cover can improve fuel efficiency, primarily by reducing aerodynamic drag and improving the vehicle’s aerodynamics. The extent of the improvement depends on several factors, including the type of cover and driving conditions.
What type of truck bed cover is best for gas mileage?
Hard tonneau covers generally offer the most significant improvement in gas mileage due to their superior aerodynamic properties. However, soft tonneau covers still provide a noticeable benefit compared to an open truck bed.
How much can I expect to save on gas with a truck bed cover?
The amount of gas saved varies depending on factors like driving habits, vehicle type, and the type of cover. Studies show potential savings ranging from 5% to 10% or more in fuel economy.
Are there any downsides to using a truck bed cover?
While offering benefits in fuel efficiency and cargo security, the main downside is the initial purchase cost and the slightly reduced access to the truck bed.
