Like the 2005 analysis, the accuracy of EPA labels varies by engine type. In 2016, the CR, EPA, and survey estimates of overall mpg are very similar. Through both its extensive survey and road test data, Consumer Reports’ new analysis shows that EPA’s updated fuel economy label is now much more accurate and reliable.
How does the EPA test fuel economy?
The EPA doesn’t just drive the vehicle to determine how many miles per gallon it gets. Both fuel economy tests are performed with the vehicle’s air conditioning and other accessories turned off. Throughout the test, a hose is connected to the vehicle’s tailpipe and collects the engine’s exhaust.
What is fuel economy label?
The Fuel Economy and Environment Label provides a Greenhouse Gas Rating, from 1 (worst) to 10 (best), based on your vehicle’s tailpipe carbon dioxide emissions only, and this rating does not reflect any GHG emissions associated with fuel production.

What is EPA fuel economy?
A key element in assessing the EPA rating for a vehicle’s average fuel economy (EPA combined) is the split between highway and city driving. The EPA rating for combined mpg presumes that we drive 55 percent of the time in the city and 45 percent of the time on the highway.

What do the EPA ratings on the car sticker tell you?
EPA Ratings on stickers determine statistics about the vehicle’s energy consumption, emission ratings and the estimated annual fuel costs. This serves as a guide for prospective buyers of vehicles in order for them to determine the estimated mileage of the vehicle.
Why is mpg so low?
A bad fuel injector or dirty/old fuel filter can drastically affect the flow of fuel into the engine. A fuel system problem is one of the most common causes of poor gas mileage. The more you run your A/C, the lower gas mileage you will get.
At what speed does EPA test highway mpg?
80 mph Vehicles are tested at a top speed of 80 mph in order to calculate the highway mpg estimates. EPA utilizes five test cycles to represent real-world driving conditions.
What is good fuel economy per Litre?
Anything that is listed as less than 6-litres/100km or more than 16.5km/1-litre is considered to be pretty good. The first (and most common) reference is litres per 100km (litres/100km). This is how many litres of fuel the car needs in order to travel 100km. You’ll often see it referred to as ‘fuel economy’.
When do the new EPA fuel economy Stickers come out?
The EPA has released a set of all-new stickers for cars and light trucks that will be mandatory for the 2013 model year. Use of the new sticker is optional for 2012, so you could see it in showrooms as early as this fall. Why this, why now?
Who is responsible for the fuel economy labels?
EPA is responsible for providing the fuel economy data that is used on the fuel economy label (or window sticker) on all new cars and light trucks. The data is also used by: The U.S. Department of Energy (DOE) to publish the annual Fuel Economy Guide; The Internal Revenue Service (IRS) to collect Gas Guzzler taxes.
When did the EPA change the way they measure fuel economy?
In 2006, EPA revised the test methods used to determine fuel economy estimates (city and highway) appearing on window stickers of all new cars and light trucks sold in the U.S. effective with 2008 model year vehicles.
How does the EPA get gas mileage data?
EPA provides IRS with the fuel economy data for vehicles which may be subject to the Gas Guzzler tax penalty. IRS is responsible for collecting those taxes from manufacturers. EPA requires auto manufacturers to change or update their MPG (miles per gallon) values on fuel economy labels (window stickers) if information comes to light that show …
