The most fuel efficient 2008-model cars available to consumers are hybrids, according to new fuel economy numbers issued by the EPA. The Toyota Prius, with a combined highway/city mileage of 46, and the Civic Hybrid with combined mpg of 42, are the only vehicles to break the 40-mpg mark. The rest of the top five most efficient vehicles are also hybrids: the Nissan Altima Hybrid, Toyota Camry Hybrid, and two-wheel-drive Ford Escape Hybrid, the only SUV at the top of the list.
California wants you to consider greenhouse gas emissions when you buy your next new car. And to help you do that, they’ve revised their mandatory Environmental Performance label for all 2009 model-year cars. All new vehicles must display the modified sticker by January 1, but some could appear on cars as early as this month.
Every American knows what “fuel mileage” is—especially these days. Whether it’s the EPA test results on the window sticker, or the actual mileage you figured out for your car, we’re all asking: How many miles can we go on a gallon of fuel? In Europe and Asia though, fuel efficiency is measured by how many liters of gas it takes to go 100 kilometers. So what's the difference? A new study released by Duke University’s Fuqua School of Business sheds some light on why "miles per gallon" is inferior to "fuel consumption."
We had an opportunity to drive the Chevy Tahoe Hybrid over the last few days and conducted two separate real-world mileage loops to determine the fuel economy for the full-size SUV. The results were impressive.
Less than two days after the EPA denied California a waiver to impose its own limits on greenhouse gases, a Congressional committee launched an investigation of the Agency’s controversial decision. According to the Los Angeles Times, EPA Administrator Stephen Johnson cut off any consultation with his technical staff for the last month and made his decision before having them write the formal, legal justification for it. Some EPA staff members believe Johnson made his decision after auto executives met with Vice President Dick Cheney.

HybridCars.com recruited over 300 hybrid drivers to participate in our own hybrid mileage study. Find out what we learned.
On Jan. 12, 2006, the Environmental Protection Agency announced that it plans to change how it calculates fuel economy for new cars and trucks to more accurately reflect the real-world mileage experience of American drivers. The EPA has increasingly come under criticism for outdated procedures that overestimate mileage by as much as 50 percent in some cases. Consumers are likely to see lower, more accurate numbers on window stickers of model 2008 vehicles arriving in dealer showrooms in the fall of 2007.
What it is the sound of one hand clapping? What is a life worth living? What is the real fuel economy of a given vehicle?
EPA mileage numbers are inaccurately high for all cars, not just hybrids. The EPA test procedure, originally developed in late 1960s, is out of date.
