As gas prices continue to rise, it's no wonder that more and more people are looking for the best gas mileage for large SUVs. After all, these vehicles are known for their spacious interiors, powerful engines, and impressive towing capacities – but they can also be notorious for their poor fuel economy. So, how can you find an SUV that won't drain your wallet at the pump? Here are five key points to keep in mind:

1. Look for hybrid or electric options. While they may be more expensive upfront, these vehicles can save you a lot of money in the long run, especially if you do a lot of driving.

2. Consider diesel engines. They typically get better gas mileage than their gasoline counterparts, and they can be a good option if you need a lot of torque for towing.

3. Look for SUVs with smaller engines. While they may not have the same level of power as larger engines, they can still provide plenty of performance while also saving you money on gas.

4. Pay attention to aerodynamics. SUVs with sleeker designs and better wind resistance will typically get better gas mileage than those with boxier, less aerodynamic shapes.

5. Don't forget about weight. The heavier an SUV is, the more fuel it will consume. So, if you don't need a lot of towing capacity or cargo space, consider a smaller, lighter SUV instead.

By keeping these key points in mind, you can find an SUV that combines the power and space you need with the fuel economy you want.

Best Gas Mileage For Large Suv FAQs

How can I improve the gas mileage of my large SUV?

There are several ways to improve the gas mileage of a large SUV. First, ensure that the vehicle is properly maintained, including regular oil changes, tire rotations, and air filter replacements. Keeping the tires inflated to the recommended pressure can also improve gas mileage. Secondly, avoid aggressive driving and maintain a consistent speed to reduce fuel consumption. Using cruise control on highways can help achieve this. Thirdly, lighten the load by removing unnecessary items from the vehicle, such as roof racks or heavy cargo. Avoid idling for extended periods of time and use the air conditioning sparingly. Finally, consider upgrading to more fuel-efficient tires or installing a high-flow air filter or performance exhaust system. Implementing these strategies can help increase gas mileage and save money on fuel costs.

How does the weight and size of a large SUV affect its gas mileage and fuel efficiency?

The weight and size of a large SUV have a significant impact on its gas mileage and fuel efficiency. Larger SUVs tend to have worse gas mileage than smaller SUVs due to their increased weight and size, which requires more fuel to move them. Additionally, larger SUVs typically have larger and more powerful engines, which consume more fuel.

Furthermore, the aerodynamics of a large SUV can also negatively affect its fuel efficiency. The large and boxy shape of an SUV creates more wind resistance, which requires more energy to move through the air.

In summary, the weight and size of a large SUV have a significant impact on its gas mileage and fuel efficiency. Larger SUVs require more fuel to move, and their boxy shape creates more wind resistance, both of which contribute to decreased fuel efficiency.

What are the EPA ratings for large SUVs with the best gas mileage?

According to the EPA ratings, the large SUVs with the best gas mileage are the 2021 Toyota Highlander Hybrid and the 2021 Ford Explorer Hybrid.

It's worth noting that the fuel economy of these vehicles can vary depending on factors such as driving habits, road conditions, and weather. Therefore, it's essential to consult the EPA ratings and conduct independent research before purchasing a large SUV.

What are the pros and cons of hybrid and diesel large SUVs for better gas mileage?

Hybrid large SUVs offer better gas mileage than diesel SUVs, making them more environmentally friendly. They also have a smoother ride and produce less noise than diesel SUVs. However, they can be more expensive to purchase, and their batteries may need to be replaced after a few years, which can be costly.

Diesel large SUVs have better fuel economy than traditional gas-powered SUVs, making them more cost-effective in the long run. They also have more torque and better towing capacity than hybrid SUVs. However, they produce more emissions than hybrid SUVs, which can be harmful to the environment. Additionally, diesel fuel is not as widely available as gasoline, which can be an inconvenience for some drivers.

What are the top large SUV models with the best gas mileage?
