How Much Do Roof Top Tents Affect Gas Mileage?

It’s imperative to know how much carrying a rooftop tent will affect your fuel consumption before purchasing one for your next camping adventure.

Fortunately, some data is available that demonstrates an estimate of just how much more fuel your vehicle is going to use when hauling a rooftop tent.

Here’s How Much Rooftop Tents Affect Gas Mileage:

A vehicle’s gas mileage is affected by the car model and the type of rooftop tent used.  According to some studies, a vehicle’s fuel economy will drop in the range of 17 percent when a rooftop tent is installed on a car. This can be due to added weight and drag from wind.

How Much Money Are We Talking Here?

Your car will likely experience a drop in fuel economy with a rooftop tent in place; however, how much it drops will depend on various factors.

You can expect to spend more on gas if you have a rooftop tent installed, in all honesty.

Below we have compiled a quick list summarising what you should consider when figuring out how much more gas you will be using and how much more you will be spending:

  • The type of roof racks you are using.
  • The size and make of your rooftop tent and whether or not it is softshell or hardshell.
  • The model of the vehicle you have and how much fuel it usually uses without a load.
  • How you have placed the rooftop tent on your vehicle.
  • The way you drive your vehicle.
  • How much torque your car has.

Should we use a 17 percent drop in fuel economy as our basis, we can work out how much more you would roughly pay for gas while using a rooftop tent.

If you drive on average around 20,000 miles a year and the cost of gas is $2.50 a gallon, you will likely spend around $460 more than usual should you have a rooftop tent installed.

Do Rooftop Tents Affect Car Performance In Other Ways?

The main reason for a car’s gas mileage being affected by a rooftop tent is because of the wind resistance it creates.

Some rooftop tents are not as aerodynamic as they could be, and as such, the drag of the car is negatively affected, which causes an increase in fuel consumption.

So we know that a rooftop ten affects our vehicle’s gas mileage, but do we know why, and does a rooftop tent affect other areas of a car’s performance? Primarily a vehicle’s center of gravity is affected.

Regardless of the type of car you have, you will notice that your vehicle’s center of gravity is affected when a rooftop tent has been installed.

When a rooftop tent has been mounted, the vehicle’s height is increased, which causes the car’s center of gravity to be affected.  When the center of gravity is altered, it reduces trail performance and the vehicle’s overall handling capabilities.

For some cars, driving around corners will slightly destabilize the vehicle, and extra attention would have to be paid to steer the vehicle.

However, it is beneficial to note that some cars retain their handling capabilities fairly well despite having a rooftop tent mounted to the roof.

Do Rooftop Tents Create Noise In The Vehicle?

Rooftop tents create noise inside a vehicle while driving it but how much noise will depend on the tent and the vehicle.

Many people who utilize jeeps, for example, will notice their rooftop tent is noisier, whereas other types of SUVs that have a rooftop tent installed might not be as noisy. The more aerodynamic the rooftop tent is, the less noisy it is, and depending on your vehicle, you might not hear anything other than slight background noise.

The place that makes the most noise the space between the rooftop tent and the roof creates a drumming-like noise that could be irritating for some.

You can negate this by purchasing a tent that fits closer to the roof racks and the roof of the vehicle.

Additionally, if you decide to use a softshell tent, you will hear more noise inside your vehicle from the rooftop tent than if you utilized a hardshell tent.

How Fast Can You Drive With A Rooftop Tent?

Now you might think that having a rooftop tent mounted will affect how fast you can drive.

Having a rooftop tent isn’t really going to affect how fast you can drive.

You can still drive normal speeds, as ultimately, the only thing that will be affected is the distance you can drive on a single tank of gas.

The faster you drive, the more fuel you will use due to the tent’s wind drag.

Therefore you can continue driving how you usually would, but if you want to be more fuel-efficient and save costs, it would be best to drive slower and with an aerodynamic rooftop tent.

Rooftop Tent Models That Are More Fuel Efficient

There happen to be many rooftop tents that are manufactured to be aerodynamic and, therefore, more fuel-efficient.

Below we will look at three brands and their respective rooftop tents that are likely to save you money on gas:

1. Roofnest Condor
