What is EPA Fuel Efficiency?

Are you wondering what EPA fuel efficiency is?

While the horsepower, luxury, and speed of any new car are incredibly important to most buyers, the car’s fuel efficiency is essential for its lifetime. While the fuel mileage statistics are determined by the EPA, there is a list of contributing factors to determine the gas mileage. Leading off with the car’s weight and the capability of the motor. Even if a vehicle is heavy, the tech of the engine could lower the amount of fuel being used in certain situations. MPG ratings usually are better for small cars, trucks, and SUVs because of their aerodynamics and total weight. These smaller cars do not take as much gas to keep them running smoothly. Something else to consider is the maintenance of the vehicle as well, doing items like making sure the tires have the correct air pressure. As we know, gas mileage is essential for any car and it takes a lot of effort to make a highly efficient vehicle.


 What is Miles Per Gallon?

What is Gas Mileage?

The distance a car could travel on a full tank of fuel is figured out by the mile per gallon it gets. ​The size of the vehicle, drivetrain (RWD or AWD), and engine horsepower all play an enormous role in determining the fuel economy for a vehicle. The numbers like small cars with hybrid options and a low vehicle weight that barely tips the scales. While the MPG can decrease during the life of a car, scheduled maintenance and regular drives are the best ways to prevent a drop in your fuel economy.


 How Do Drive Modes Affect Miles Per Gallon

Gas Economy & Drive Modes

These days many vehicles have cylinder deactivation and drive modes to save fuel when it’s not needed. A performance mode will offer a performance-based drive while “Eco” (or Economy) mode will save fuel. Between driving modes and cylinder deactivation, vehicles offer better miles per gallon than ever before.

Highway vs City

Mileage in City vs Highway

Looking at MPGs, there are two different numbers that wrap up the gas mileage, city and highway miles per gallon. Driving conditions in the real world are very different when compared to the environment in testing facilities and the results speak for themselves. Noting the 2 different MPG ratings shows how driving habits will alter a vehicle’s miles per gallon. Your driving habits will absolutely affect the miles per gallon, ​so noting both gas mileage ratings gives a more accurate description of your vehicle. Considering all the starting and stopping of city driving compared to the constant speed of highway driving, clearly, highway driving should get a higher amount of MPGs.
