What Is A Midsize SUV?

Let’s talk about SUV categories first. Sometimes, it can be confusing with so many sizes and categories.

SUV is an acronym for Sports Utility Vehicle, which doesn’t really define what an SUV is exactly. To classify as an SUV, the car will need to have room for multiple passengers, higher ground clearance, and rear-wheel drive.

Originally, the sports utility vehicle was created to have a large interior as well as towing capabilities. Nowadays, there are a wide variety of SUVs, such as:

The variety of SUV sizes use up different amounts of gas, depending on the size of the car and the power of the engine. Most of the time, compact SUVs get the best fuel economy while the full-size gets the worst fuel economy. 

However, many consumers purchase SUVs because of their large size and comfortable design, not for the fuel economy.

Driving a gas-powered vehicle, especially a higher-end one, can be expensive. That’s why many people want to know which midsize SUVs use regular gas.  

In comparison, driving a gas car can be much more economical than driving a diesel-powered car.

How Do Diesel And Gas Engines Impact The Environment?

The United States Environmental Protection Agency (EPA) cites diesel engines as one of the biggest causes of air pollution. 

With elements such as sulfur, nitrogen oxides, and carbon monoxide being put out into the environment, scientists and local governments alike have been calling for a federal ban or at least a strong limitation on diesel cars and trucks. Some local governments like California have taken action on their own.

They’ve been instilling new clean air regulations on diesel fuel with the end goal of banning the sale and production of unclean diesel cars by 2035. 

Many car companies have the option for normal engines or diesel if the car allows for it. This choice will be available when you customize a new car through their dealerships.

With the national average price for regular gas currently at $3.221 and diesel being $3.836, picking a car that is cost-effective is important. 

Federal taxes for diesel fuel of 24.3 cents per gallon is 6 cents higher than the corresponding tax on gasoline. 

So even if you’re not climate-conscious in your car decisions, that extra money in your pocket will be nice! That’s why it’s important to know which midsize SUVs use regular gas.
