How we get the fuel economy estimates
The fuel economy estimates are the average of test results conducted for the U.S. Environmental Protection Agency (EPA). The vehicles are driven by professional drivers in controlled laboratory conditions. The results are adjusted to account for differences between the controlled laboratory conditions and real-world driving. Using these procedures ensures that all testing is fair so that you may compare the results of different vehicles with confidence. The U.S. Department of Energy prints the results in this Guide as an aid to consumers.
There are two fuel economy estimates for each vehicle
'City' represents urban driving where the vehicle is started in the morning after being parked all night and driven in stop- and-go rush-hour traffic.
'Highway' represents a mixture of rural and interstate highway driving in warmed-up vehicles typical for longer trips.
Use this guide before buying a vehicle
Use the fuel economy values to compare different vehicles. You need not sacrifice utility or size to make a difference. Within the same class of vehicles (e.g., midsize car, SUV or minivan) there is a range of fuel economy. The most fuel-efficient vehicles in each class have been printed in blue ink and preceded by a checkmark. By paying attention to fuel economy, as well as to the other features you want, you can help protect the environment and save yourself money.
Why your fuel economy can vary
No test can simulate all possible combinations of conditions: climate, driver behavior, and car care habits. Actual fuel economy depends on how, when, and where a vehicle is driven. EPA has found that the fuel economy obtained by most drivers will be within a few miles per gallon (mpg) of the estimates in this booklet.
