How is EPA Gas Mileage Determined?

Searching for how EPA gas mileage is determined?

While the power, luxury, and speed of any new car are very important to almost all buyers, gas mileage is key for its lifetime. While the miles per gallon are determined by the EPA, there is a list of parts to figure out the gas mileage and they vary. Leading off with the car’s weight and how much power it has. Just because the vehicle is on the heavier side, the tech of the engine could still lower how much fuel is being used. Fuel economy ratings usually are more efficient for small vehicles because of their total weight and aerodynamics. In general, these small vehicles do not need as much fuel to keep them running smoothly. Another factor to consider is the maintenance of the car, making sure the tires have the correct air pressure to lighten the load. All in all, gas mileage is important for any vehicle and it takes many of the components working together to create an efficient vehicle.

What is Gas Mileage?

MPGs are the most consistent way to calculate how far any vehicle is able to go with a full tank of fuel. ​The size of the car, drivetrain (2WD or 4WD), and engine horsepower all play a huge part in determining the fuel economy for the vehicle. The stats like smaller sedans with hybrid models and a curb weight that’s light enough that just barely tip the scales. While gas mileage can decrease over time, scheduled maintenance and frequent drives are the simplest ways to keep those MPGs high.

Fuel Mileage in Highway vs City

Looking at MPGs, there are two results that define the gas mileage, the miles per gallon in the city and highway. Rear world driving conditions are very different compared to the environment in testing facilities and the numbers speak for themselves. Noting the two separate MPG ratings shows how driving habits will absolutely alter a vehicle’s fuel economy. Your driving habits will absolutely affect a vehicle’s miles per gallon, ​so providing both gas mileage ratings provides a true expectation for your car’s gas mileage. With all the stop and go of city driving contrasted with the constant movement of highway driving, it’s clear that highway driving should get a higher amount of gas mileage.

Do Drive Modes Affect Gas Economy

Nowadays many vehicles have cylinder deactivation and customizable drive modes to preserve fuel when desired. A sporty-type mode will offer a performance-based experience while “Eco” mode prioritizes MPGs. Between cylinder deactivation and driving modes, new vehicles are more fuel-efficient than ever before.
