Do Bed Covers Help Improve Gas Mileage?

 If you’re looking for ways to squeeze out a little more fuel efficiency from your truck, you’ve probably heard that installing a bed cover can help improve gas mileage. But is that just a marketing gimmick, or does it actually make a difference? The short answer: Yes, a bed cover can improve fuel economy—but the actual gains depend on multiple factors like driving speed, truck design, and the type of cover you choose. At Deviate Dezigns, we know that every performance mod has to serve a purpose, so let’s break down whether a bed cover is worth it if you’re looking to save at the pump.

The Science Behind Bed Covers and Fuel Economy

Trucks are built for utility, but that open bed creates a lot of aerodynamic drag when air gets trapped in the back. As you drive, air flows over the cab and then tumbles into the bed, creating turbulence that can slow your truck down and force the engine to work harder to maintain speed. A bed cover helps smooth out that airflow, reducing drag and potentially improving gas mileage.

Types of Bed Covers and Their Impact on MPG

Not all bed covers perform the same when it comes to fuel savings. Here’s a breakdown of the different types and how they affect gas mileage:

• Soft Roll-Up Covers: These lightweight covers offer some aerodynamic benefits but aren’t as rigid, meaning they can slightly reduce drag but may not make as much of an impact as other styles.

• Hard Folding Covers: These provide a more solid surface for air to flow over, reducing turbulence and offering better MPG improvements.

• Retractable Covers: Designed for convenience, retractable covers create a relatively smooth surface and help with aerodynamics, although their impact varies based on design.

• One-Piece Hard Covers: The best option for aerodynamics, these covers create a completely flat surface, minimizing drag and offering the highest potential fuel savings.

Real-World Factors That Influence Fuel Economy

While a bed cover can improve gas mileage, it’s not the only factor at play. Other variables, like driving speed, truck modifications, and tire choice, will also impact how much fuel you burn. For example, a truck with oversized off-road tires will see less of a benefit from a bed cover because of the extra rolling resistance. Similarly, driving at highway speeds will maximize the benefits of a bed cover since aerodynamic drag plays a bigger role at higher speeds.

Is a Bed Cover Worth It for Fuel Savings?

If you’re strictly looking to buy a bed cover for gas mileage, the savings alone may not be enough to justify the purchase. However, bed covers offer a lot more than just potential MPG improvements. They help protect cargo from weather, keep your gear secure, and improve the overall look of your truck. If you’re considering a bed cover for multiple reasons, the fuel savings are just an added bonus.

The Right Bed Cover for Your Build

A bed cover can help improve your truck’s gas mileage by reducing aerodynamic drag, but the actual savings depend on your driving habits, truck setup, and the type of cover you choose. If you want the best balance of performance, security, and efficiency, investing in a high-quality hard cover is the way to go.
