MythBusters tested the ‘tonneau covers save gas’ claim and found it plausible. Their experiments indicated a slight improvement in fuel efficiency with a cover on a pickup truck, suggesting potential gas savings over time.
The Myth: Tonneau Covers and Fuel Efficiency
Understanding Tonneau Covers
Tonneau covers are the hard or soft coverings that go over the bed of a pickup truck. They are designed to protect cargo from theft and the elements.
Many truck owners also believe that these covers lead to improved gas mileage, thus saving money on fuel in the long run.
The Aerodynamics Argument
The theory behind the belief that tonneau covers save gas is rooted in aerodynamics.
A pickup truck with an open bed creates a drag effect as air flows into the bed and forms a miniature windstorm. It is thought that a tonneau cover streamlines the vehicle, allowing air to flow over it more smoothly and reducing drag.
Diverse Opinions on Fuel Savings
Manufacturers often claim that their tonneau covers can improve fuel efficiency, sometimes by a significant percentage.
Many drivers back up these claims with their personal experiences. However, some skeptics argue that the savings are minimal or nonexistent.
Drivers’ Testimonials and Manufacturer Claims
There is no shortage of positive testimonials from truck owners who have experienced fuel savings after installing a tonneau cover.
On the other hand, there are those who have noticed little to no change. This disparity in experiences has fueled the debate on the topic.
Investigating the Myth: Mythbusters and Other Studies
Mythbusters’ Tonneau Cover Experiment
The popular TV show Mythbusters took on the challenge of testing whether tonneau covers save gas.
They conducted an experiment with a pickup truck, driving it with and without a tonneau cover and measured the fuel consumption.
The results indicated a slight improvement in gas mileage with the tonneau cover, leading them to declare the claim plausible.
Additional Research Studies
Aside from Mythbusters, other research studies have been conducted to test the same claim.
These studies utilize various methodologies, including wind tunnel tests and on-road driving tests, to measure the impact of tonneau covers on fuel efficiency.
Comparative Results Across Truck Models
Different truck models have varying aerodynamic designs, which can influence how much a tonneau cover affects fuel economy. Research has shown that the impact can vary depending on the make and model of the truck.
Variety of Tonneau Cover Designs
There are several types of tonneau covers, including soft roll-up, hard folding, and retractable covers. The differences in design and materials can also affect their efficiency in improving gas mileage.
Analyzing the Evidence: Do Tonneau Covers Really Save Gas?
Interpreting Research Data
When looking at the data from Mythbusters and other studies, it’s important to interpret the results carefully.
While there may be a slight improvement in fuel efficiency, the extent of the savings can vary widely based on several factors.
Factors Affecting Fuel Economy
Driving habits such as speed and acceleration, the condition of the truck, and environmental conditions like wind and terrain all play roles in a vehicle’s fuel economy. These factors can either enhance or negate the benefits of a tonneau cover.
Considering the Cost-Benefit
To truly evaluate the value of a tonneau cover, one must consider the cost of the cover against the potential fuel savings. If the improvement in gas mileage is small, it may take a long time to recoup the initial investment.
Real-World Implications for Truck Owners
Truck owners need to weigh the practical benefits of a tonneau cover, such as cargo protection and aesthetics, against the potential for fuel savings.
For some, the decision may hinge more on these practical considerations than on gas mileage alone.
FAQs About Tonneau Covers Saving Gas MythBusters
Did MythBusters prove that tonneau covers save gas?
MythBusters found the claim that ‘tonneau covers save gas’ to be plausible, indicating a slight improvement in fuel efficiency with a cover on a pickup truck.
How much gas can you save by using a tonneau cover?
The exact amount of gas saved can vary, but MythBusters’ experiments suggested that there could be potential gas savings over time with the use of a tonneau cover.
Is it worth getting a tonneau cover for fuel efficiency?
Considering the plausible improvement in fuel efficiency, it can be worth getting a tonneau cover for those looking to potentially save on gas over time.
What are the benefits of a tonneau cover besides gas savings?
Beyond gas savings, tonneau covers also provide security for cargo, protection from the elements, and can enhance the appearance of a pickup truck.
Can all types of tonneau covers improve fuel efficiency?
The improvement in fuel efficiency may vary depending on the design and type of tonneau cover, but generally, tonneau covers are believed to reduce aerodynamic drag.
Final Thoughts
MythBusters’ investigation into the efficacy of tonneau covers on fuel efficiency yielded a ‘plausible’ verdict.
Their empirical tests showed a modest increase in miles per gallon when a pickup truck was equipped with a tonneau cover, indicating that drivers could indeed experience gas savings over the long haul.
