Maximizing Efficiency: The Benefits of a Retractable Tailgate for Pickup Trucks

  • Thread starter Loren Booda
  • Start date
In summary, there has been discussion about why pickup trucks do not come with a retractable tailgate for highway driving. It has been suggested that this could potentially increase the truck's highway consumption by at least 1/2 MPG. However, there have been tests done, possibly by Mythbusters, that have shown that there is not a significant difference in drag with the tailgate up or down. Additionally, the tailgate can also act as a boundary for incoming stream, reducing pressure drag.

Why don't pickup trucks come with a tailgate designed to retract (manually) before highway driving when practicable? It seems self defeating to have such inefficient drag as from an upright tailgate. I believe that by this retraction the truck's highway consumption would increase by at least 1/2 MPG.

I'm not sure about the efficiency of that. Someone (I think that it was Mythbusters) did some tests that showed not a lot of difference in drag with the tailgate up or down. That's all that I have for now, since my memory is failing.

yes, they showed that tail gate up maintains a nice separation bubble behind the tail gate(towards the truck), and act as a boundary for incoming stream, hence reducing pressure drag
 

FAQ: Maximizing Efficiency: The Benefits of a Retractable Tailgate for Pickup Trucks

What is a retractable tailgate for pickup trucks?

A retractable tailgate is a type of tailgate for pickup trucks that can be folded or rolled up when not in use. This allows for easier access to the truck bed and can improve the aerodynamics of the truck, resulting in better fuel efficiency.

How does a retractable tailgate improve efficiency?

A retractable tailgate can improve efficiency in several ways. By allowing for easier access to the truck bed, it can save time and effort for loading and unloading. Additionally, when the tailgate is folded or rolled up, it can reduce drag and improve the aerodynamics of the truck, resulting in better fuel efficiency.

Are there any other benefits of a retractable tailgate?

Aside from improving efficiency, a retractable tailgate can also provide added security for items in the truck bed. When the tailgate is locked in place, it can prevent theft or shifting of items during transportation. Additionally, a retractable tailgate can also improve the overall appearance of the truck.

Are there any downsides to using a retractable tailgate?

One potential downside of a retractable tailgate is the cost. These tailgates can be more expensive than traditional tailgates, so it may not be a feasible option for all truck owners. Additionally, retractable tailgates may be more susceptible to damage or malfunctions compared to traditional tailgates.

Can a retractable tailgate be installed on any pickup truck?

While there are universal retractable tailgate options available, not all pickup trucks may be compatible with this type of tailgate. It is important to check the specifications and compatibility of the tailgate before purchasing to ensure proper installation and functionality.
