SUVs are everywhere these days, they have become the default choice for more and more individuals in recent years. While they do have their advantages such as spaciousness, versatility, and ruggedness that many consumers find appealing.
However, one major concern for SUV owners is gas mileage. SUVs are notorious for their lower fuel efficiency compared to smaller cars, and this can be a significant factor to consider when purchasing an SUV.
Gas mileage is important for several reasons. Firstly, it affects the cost of owning and operating an SUV. With rising fuel prices, a vehicle that guzzles gas can quickly become a financial burden. Secondly, high gas mileage has a negative environmental impact. Vehicles that consume more fuel emit more greenhouse gases, contributing to climate change.
Lastly, gas mileage affects the range of an SUV. A vehicle with poor fuel efficiency will require more frequent refueling, limiting its ability to travel long distances without stopping.

Understanding Gas Mileage Ratings for SUVs
The official gas mileage ratings for SUVs are determined by the Environmental Protection Agency (EPA) through standardized testing procedures. These ratings are expressed in miles per gallon (MPG), however, it’s important to note that these ratings are based on laboratory tests and may not reflect real-world driving conditions.
The EPA provides two types of MPG ratings: city and highway. The city MPG rating represents the fuel efficiency during stop-and-go driving in urban areas, while the highway MPG rating represents fuel efficiency during steady-state cruising on highways.
One thing to note here, while the city rating is typically lower than the highway rating because urban driving involves more frequent stops and starts, which require more energy. In hybrid cars, it quite the opposite, the reason is hybrid cars utilize those same frequent stopping instances to generate electric charge and send it back to the battery.
What Factors Affect SUV Gas Mileage?
Several factors can influence the gas mileage of an SUV. Understanding these factors such as:
- The weight and size of an SUV. Generally, larger and heavier SUVs require more energy to move, and generate more aerodynamic drag.
- The engine size and type. Smaller engines tend to be more fuel-efficient and require less energy to operate. Additionally, technologies such as turbocharging and direct injection, can improve fuel efficiency by optimizing combustion.
- The type of transmission. Automatic transmissions are still slightly less efficient than manual transmissions. However, some modern automatic transmission narrowed this gap in recent years.
- Driving habits. Aggressive driving, such as rapid acceleration and hard braking, can significantly reduce fuel efficiency of your vehicle.
- Traffic conditions can also influence gas mileage. Driving in heavy traffic or on hilly terrain can increase fuel consumption due to frequent stops and starts or increased load on the engine.
- Weather conditions. Driving on snow or mud requires to put the transmission on lower gears, which results in the engine revving harder to move the vehicle.
- Vehicle maintenance. Neglecting regular maintenance can lead into multiple issues such as clogged fuel injectors or dirty oxygen sensor which can alter the air fuel ration and cause higher fuel consumption.
