WASHINGTON, DC -- Diesel-powered vehicles deliver more real-world miles per gallon than the numbers on new-car window stickers currently indicate, according to the U.
S. Environmental Protection Agency's "YourMPG" database. The findings were detailed in EPA's "Final Technical Supporting Document" accompanying the agency's new fuel economy labeling rule released Tuesday.
The "YourMPG" data, compiled by the Oak Ridge National Laboratory, includes 221 diesel drivers measuring their own fuel economy and providing their real-world MPG to an Internet database. EPA then compared this real- world data with the projected fuel economy calculations it requires for all new cars.
"As can be seen, diesels appear to perform the best with respect to their label fuel economy, outperforming the label by 4.3%," the EPA technical support document said. Diesel was the only power source to see an increase in real-world MPG. Gasoline cars decreased by between 1.4%-1.7%, while hybrid owners saw their real-world mileage drop by over 8% compared to the current fuel economy label.
The link provides complete information about the new EPA test that will on average drop car fuel economy 12% in the city and 8% on the highway.
