Your actual gas mileage* depends on many variables, including your driving behavior and speed, the load you are carrying, even the direction of the wind. The GM Fuel Economy and CO2 Calculator will help you get a better idea of how these factors work. Customize the Calculator with your driving habits and the price you pay for fuel, and it will calculate your annual fuel costs.
The calculator will also show you how much CO2 your vehicle emits, based on its fuel consumption. Change the amount of fuel you use to see how it changes your personal vehicle’s CO2 emissions. And finally, take the Driver’s Quiz to see how your driving habits and vehicle condition can lower the average mile per gallon your vehicle receives.
*The U.S. Environmental Protection Agency requires that all automakers test their vehicles' fuel economy under simulated driving conditions. The EPA confirms the accuracy of the manufacturers' tests. Fuel economy regulations do not apply to heavy-duty vehicles, which do not have fuel economy labels and are not included in this listing.
