What is EPA Fuel Efficiency?

Looking for what EPA fuel efficiency is?

While the speed, power, and luxury of a new car are very important to almost all prospective buyers, miles per gallon are essential for its lifetime. While the gas mileage numbers are given by the EPA, there are several elements to determine the official gas mileage. Starting with the car’s weight and how much power it has. Even if a car is heavy, the engine technology could still lower how much gas is being used in specific situations. EPA ratings are usually higher for smaller vehicles because of their aerodynamics and total weight. In general, these smaller vehicles don’t need as much gasoline to keep them running smoothly. Another consideration is the overall maintenance of the car, truck, or SUV as well, making sure the tires have the correct pressure. As we know, gas mileage is very important for all vehicles and it takes a lot of effort to make an efficient vehicle.

Do Driving Modes Affect Gas Economy

Many cars that have been produced in the past several years have equipped customizable drive modes to fit driver’s habits and save fuel. A performance driving mode will offer a performance-based drive while “Eco” (or Economy) mode prioritizes MPGs. Between driving modes and cylinder deactivation, cars offer better MPGs than ever before.

MPG Explained

The fuel economy is the best way to figure out how far any car is able to go with a full tank of gasoline. ​The size of the car, drivetrain (4WD or 2WD), and engine horsepower all play a huge part in determining the fuel economy for a vehicle. The numbers like small sedans with hybrid models and a vehicle weight that’s light enough that just barely tip the scales. While the MPG can decrease during the lifespan of a car, frequent drives and updated maintenance are the easiest ways to keep your MPGs high.

Gas Economy in Highway vs City

When examining miles per gallon, there are two results that wrap up the gas mileage of the car, the MPGs in the highway and city. The driving conditions in the real world are much different compared to the testing conditions and the results reflect that. Calculating the two separate fuel economy ratings shows how driving habits will alter the vehicle’s miles per gallon. Your driving habits will absolutely affect the fuel economy, ​so providing both gas mileage ratings provides a true expectation for your vehicle’s fuel economy. Considering all the stop and go of city driving contrasted with the constant movement of driving on the highway, it’s clear that highway driving should get higher MPGs vs. driving in the city.
