The Science Behind Aerodynamics and Fuel Economy
Learning about truck bed aerodynamics is crucial for better gas use. It involves many factors that impact your vehicle’s performance.
Coefficient of Drag (Cd) Explained
The Coefficient of Drag (Cd) shows how well your truck cuts through air. A lower Cd means less air resistance and better gas mileage. Accessories like tonneau covers can lower this drag, saving fuel.
How Aerodynamics Affects Truck Performance
Aerodynamics are key to your truck’s performance. An open truck bed causes turbulence, raising drag and cutting fuel efficiency. Driving at 65mph instead of 60mph can cut fuel economy by 1.5mpg due to more air resistance.
The Role of Wind Resistance in Fuel Consumption
Wind resistance greatly affects your truck’s gas use. A study found a 1mpg average increase with a tonneau cover. This small gain can save up to $8,000 a year for big trucks.
| Factor | Impact on Fuel Economy |
|---|---|
| Tonneau Cover | +1 mpg (average) |
| Speed Increase (60mph to 65mph) | -1.5 mpg |
| Aerodynamic Modifications | 17-18 mpg (average on road trips) |
By grasping these aerodynamic principles, you can choose the right truck bed accessories and driving habits. This will help you improve your fuel economy.
Types of Tonneau Covers and Their Impact on MPG
Truck bed covers come in various styles, each affecting fuel savings differently. Your choice can impact vehicle performance and aerodynamics. Let’s explore the main types and their potential for drag reduction.
Soft Roll-Up Covers
Soft roll-up covers are popular for their affordability and ease of use. They’re lightweight, which is good for fuel efficiency. But their flexible nature means they’re less streamlined, potentially reducing gas savings compared to rigid options.
Hard Folding Covers
Hard folding covers offer a balance of durability and aerodynamics. They create a smoother surface over your truck bed, improving airflow. Some tests show these covers can boost fuel economy by up to 10%.
Retractable Covers
Retractable covers are a versatile option. They’re typically lighter than folding covers and quick to open or close. Their streamlined design can contribute to better gas mileage by reducing wind resistance.
| Cover Type | Weight | Aerodynamics | Fuel Savings |
|---|---|---|---|
| Soft Roll-Up | Light | Moderate | Low-Moderate |
| Hard Folding | Heavy | Good | Moderate-High |
| Retractable | Medium | Excellent | High |
Remember, the impact on fuel economy varies based on driving conditions, truck model, and cover design. Choose a cover that suits your needs while potentially boosting your truck’s efficiency.
Does Bed Cover Improve Gas Mileage: Analyzing the Evidence
Many truck owners wonder if bed covers can help with gas mileage. With fuel prices going up, finding ways to save on gas is important. Some think tonneau covers might help by cutting down on wind resistance and saving fuel.
Studies have looked into how tonneau covers affect gas mileage. The SEMA Wind Tunnel Study found a small increase in mpg with covers on. This research on tonneau cover gas mileage shows possible fuel savings. But, results can vary based on driving conditions and the type of cover.
However, there are also conflicting results. Some tests show better mpg, while others don’t. The MythBusters and Consumer Reports tests gave different results. This leaves truck owners unsure about the real benefits.
“The impact of tonneau covers on fuel efficiency is not straightforward. Various factors come into play, making it crucial to consider individual circumstances.”
To really know if a bed cover helps with gas mileage, think about these things:
- Driving speed and conditions
- Cover material and weight

Even though there’s debate, many truck owners say tonneau covers work for them. They not only might save on gas but also protect cargo and look better. So, deciding to get a tonneau cover should weigh both possible mpg gains and other benefits.
The SEMA Wind Tunnel Study: Uncovering the Truth
In 2007, the SEMA Wind Tunnel Study aimed to see how tonneau covers affect truck fuel economy. It tested four truck models with 13 different covers. This research showed the potential for gas savings with these truck accessories.
Study Methodology and Truck Models Tested
The study happened at AeroDyn Wind Tunnel in Mooresville, North Carolina. It used a full-size wind tunnel. The Chevrolet Silverado, Dodge Ram, Ford F-150, and Nissan Titan were tested at various speeds with different tonneau covers.
Results and Implications for Fuel Efficiency
The study found a 5.7% reduction in drag with tonneau covers. This led to a 1.8% increase in fuel efficiency. Such small improvements can add up over time, leading to better mileage.
| Speed (mph) | Drag Reduction | Potential MPG Boost |
|---|---|---|
| 85 | 7.8% | 1.0 |
| 65 | 5.5% | 0.5 |
| 55 or below | Minimal | <0.1 |
The study found that solid fiberglass tonneau covers are best for fuel economy. For daily drivers, these accessories can offer small but steady mpg boosts, especially on highways.
MythBusters Take on Tonneau Covers and Fuel Economy
The TV show MythBusters looked into how tonneau covers affect fuel economy in a 2006 episode. This experiment got a lot of attention, with 43,000 views and 37 replies from 23 people. It made many wonder about truck bed cover gas mileage.
MythBusters tested different truck modifications, including a hard tonneau cover, at 55 mph for 5-10 miles. They found that the tonneau cover didn’t really help with fuel efficiency. However, they noticed that driving with the tailgate up made airflow smoother. But, lowering it made fuel economy worse.
Here’s a breakdown of their findings:
- Tailgate up: 14.2 mpg
- Tonneau cover: No significant change
- Mesh tailgate: 5% increase (14.92 mpg)
Some critics say the study’s use of just one truck model at a low speed might not show real-world results. Many drivers drive faster, where tonneau covers might make a bigger difference in fuel efficiency.
The MythBusters test was fun but showed how tricky it is to figure out truck bed cover gas mileage. It’s interesting to note that other studies, like SEMA’s wind tunnel research, have found tonneau covers can improve fuel economy.
Consumer Reports Test: A Different Perspective
In 2013, Consumer Reports did a study on truck bed tonneau cover benefits. They looked at how tailgate position and soft tonneau covers affect fuel economy. Their results changed what we thought about truck bed cover aerodynamics.
Test Setup and Methodology
They used a Dodge Ram V8 to check fuel efficiency under different conditions. They tested the truck with the tailgate up, down, and with a soft tonneau cover. They wanted to see how these setups affected gas mileage.
Surprising Findings and Their Implications
The results were unexpected. They found that driving with the tailgate down and using a soft tonneau cover slightly reduced fuel economy. This goes against what many thought about truck bed cover airflow and its effect on fuel efficiency.
These findings are interesting, but the study had its limits. It only used one truck model and one type of tonneau cover. This might not cover the wide range of trucks and covers out there.
The Consumer Reports test shows how complex fuel economy in trucks can be. It points out that the link between tonneau covers and gas mileage is more complex than we thought. It shows we need more detailed studies in this field.
