Tonneau Cover Gas Mileage Mythbusters

Tonneau Cover Gas Mileage Mythbusters

The idea that installing a tonneau cover on your truck will improve your gas mileage has been explored by the popular TV show “Mythbusters.”

Their tests showed that while a tonneau cover can indeed reduce wind drag on your truck, the resulting improvement in gas mileage is likely to be minimal.

In their experiments, the Mythbusters found that a tonneau cover could improve gas mileage by up to 5%, but only in certain conditions.

Specifically, the improvement was most noticeable at highway speeds and in trucks with tailgates that were left open.

The improvement was less significant in other situations, such as around-town driving or with a closed tailgate.

Overall, the impact of a tonneau cover on gas mileage is likely to be relatively small.

If you’re considering purchasing one for other reasons, such as improved security or weather protection, those benefits may be more significant than any potential gas savings.

Real-World Studies: Analyzing the Impact of Tonneau Covers on Gas Mileage

There have been a number of real-world studies that have analyzed the impact of tonneau covers on gas mileage.

The results of these studies have been mixed, with some studies showing a significant improvement in gas mileage while others showing no improvement or even a decrease in gas mileage.

One of the most comprehensive studies on the impact of tonneau covers on gas mileage was conducted by the University of Michigan Transportation Research Institute.

The study found that tonneau covers can improve gas mileage by an average of 2.3%.

However, the study also found that the type of tonneau cover can make a difference, with soft tonneau covers providing the most improvement and hard tonneau covers providing the least improvement.

Another study, conducted by the American Council for an Energy-Efficient Economy, found that tonneau covers can improve gas mileage by an average of 1.5%.

However, this study also found that the impact of tonneau covers on gas mileage can vary depending on the type of truck and the driving conditions.

Overall, the evidence suggests that tonneau covers can improve gas mileage, but the improvement is likely to be modest.

The type of tonneau cover, the type of truck, and the driving conditions can all affect the amount of improvement that is seen.

What are the Effects of Tonneau Covers on Fuel Consumption?

What are the Effects of Tonneau Covers on Fuel Consumption

Improved Aerodynamics for Reduced Drag

When you install a tonneau cover on your truck bed, it helps streamline the airflow, reducing drag as you drive.

By minimizing the resistance against your vehicle, tonneau covers contribute to improved aerodynamics, resulting in reduced fuel consumption.

Decreased Turbulence and Air Circulation

Tonneau covers create a smooth surface over your truck bed, minimizing turbulence and air circulation.

This reduction in disruptive airflow can lead to improved fuel efficiency by reducing the drag coefficient and allowing your vehicle to glide more smoothly through the air.

Prevention of Air Vortices and Lift

A well-fitted tonneau cover can help prevent the formation of air vortices or pockets of swirling air above your truck bed.

These vortices can create lift, which increases aerodynamic drag and fuel consumption.

By eliminating or minimizing air vortices, tonneau covers help maintain stable airflow and reduce energy loss.

Protection from Wind Resistance

When driving at high speeds, wind resistance can significantly impact fuel consumption.

Tonneau covers act as a barrier, shielding your truck bed and cargo from direct exposure to wind, thereby reducing the impact of wind resistance.

This effect can lead to improved fuel efficiency, particularly during highway driving.

Enhanced Stability and Reduced Vehicle Sway

Enhanced Stability and Reduced Vehicle Sway

Tonneau covers add an extra layer of stability to your truck, reducing vehicle sway caused by wind turbulence.

This increased stability can result in improved handling and control, which can positively influence fuel efficiency.

By minimizing unnecessary movements, tonneau covers help your vehicle maintain its intended trajectory, reducing fuel wastage.

Protection from Drag-Inducing Cargo

If you regularly transport items in your truck bed, their exposed presence can create additional drag, negatively impacting fuel efficiency.

Tonneau covers provide a protective shield, preventing drag-inducing factors such as bulky cargo or uneven surfaces.

By keeping your truck bed smooth and streamlined, tonneau covers help optimize fuel consumption.

Minimized Air Resistance from Truck Bed Accessories

Truck bed accessories like bed extenders, racks, or toolboxes can disrupt smooth airflow and increase drag.

Tonneau covers, especially low-profile ones, create a unified surface, reducing the air resistance caused by these accessories.

This reduction in drag helps maintain better fuel efficiency, even when additional equipment is present.

Potential Fuel Savings in Long-Term Use

When considering the effects of tonneau covers on fuel consumption, it’s important to note that the cumulative impact of improved aerodynamics and reduced drag can lead to long-term fuel savings. 

While individual savings may vary based on driving habits, vehicle type, and other factors, utilizing a tonneau cover consistently can reduce fuel consumption over time.

What Are The Disadvantages Of Tonneau Covers?

What Are The Disadvantages Of Tonneau Covers

Limited Accessibility to the Truck Bed

One drawback of using a tonneau cover is the reduced accessibility to the truck bed.

Depending on the type of tonneau cover you choose; it may require partial or complete removal to access the contents of your truck bed.

This can be inconvenient when loading or unloading large or bulky items quickly.

Restricted Cargo Height and Capacity

Tonneau covers typically sit flush with the truck bed, which can limit the height and capacity of cargo that can be accommodated.

If you frequently transport tall or oversized items, the restricted cargo height imposed by the tonneau cover may pose a challenge.

It’s important to consider the dimensions and load capacity requirements of your specific hauling needs.

Installation and Removal Effort

Installing and removing a tonneau cover can be a time-consuming process, especially for certain types of covers that require additional hardware or tools.

While many tonneau covers are designed for easy installation and removal, it still requires some effort and may not be as convenient as having an open truck bed for immediate access.

Cost Considerations

Tonneau covers can vary significantly in cost, depending on the type, brand, and features.

While there are options available to suit various budgets, it’s important to consider the cost implications and weigh them against the benefits and disadvantages.

Investing in a high-quality tonneau cover may come with a higher upfront cost, but it can offer better durability and long-term value.

Style and Aesthetics

While subjective, some individuals may find that adding a tonneau cover alters their truck’s overall look and aesthetics.

Depending on personal preferences and the specific design of the tonneau cover, it may impact the visual appeal or alter the vehicle’s original appearance. I

It’s important to choose a tonneau cover style and design that aligns with your desired aesthetic and complements the overall look of your truck.
