* Engine size and type: Vehicles with larger engines typically get worse gas mileage than those with smaller engines. This is because larger engines require more fuel to produce the same amount of power. Additionally, vehicles with more cylinders typically get worse gas mileage than those with fewer cylinders.
* Vehicle weight: Heavier vehicles typically get worse gas mileage than lighter vehicles. This is because heavier vehicles require more energy to move.
* Aerodynamics: Vehicles with poor aerodynamics get worse gas mileage than those with good aerodynamics. This is because vehicles with poor aerodynamics create more drag, which increases the amount of fuel needed to move the vehicle.
* Tire pressure: Underinflated tires can reduce gas mileage. This is because underinflated tires increase rolling resistance, which makes it more difficult for the vehicle to move.
* Driving habits: Aggressive driving habits, such as speeding and rapid acceleration, can reduce gas mileage. This is because these habits require the engine to work harder, which uses more fuel.
As a result of these factors, the mileage of a vehicle can vary significantly from one model to another. For example, a small, lightweight car with a fuel-efficient engine can get up to 50 miles per gallon (mpg), while a large, heavy SUV with a powerful engine may only get 15 mpg.
