	Fuel efficiency - Wikipedia, the free encyclopedia
		Fuel efficiency sometimes means the same as thermal efficiency or fuel economy.
		But fuel efficiency can also mean the output one gets for a unit amount of fuel input such as "miles per gallon" for an automobile.
		This last term "liters/100km" is also a measure of "fuel economy" where the input is measured by the amount of fuel and the output is measured by the distance travelled.

	Vehicle Fuel Economy Standards Big Energy Savings at a Modest Cost (Site not responding. Last check: 2007-10-31)
		The 1985 average fuel economy standard of 27.5 mpg for cars has not been raised in the intervening 16 years, and the light truck standard increased only about 1 mpg in the same period.
		Engineering analyses show that this level of fuel economy improvement over the next 10–15 years is feasible and could be achieved using "conventional" (non-hybrid) technologies through a combination of streamlining, reduced tire rolling resistance, engine improvements, optimized transmission, and effective use of the upcoming transition to higher voltage automotive electrical systems.
		Given the importance of dramatically improving new vehicle economy in the coming decades, federal participation should be expanded in research and development of highly efficient vehicles—both light and heavy duty—and technologies such as fuel cells, hybrid-electric drivetrains, and lightweight materials.

	ET 11/99: Light-duty automotive technology and fuel economy trends through 1999
		Fuel economy is directly related to carbon dioxide emissions, the most prevalent pollutant associated with global warming, and light vehiclesontribute about 20 percent of all US carbon dioxide emissions.
		The 1999 fuel economy average is the lowest value since 1980 and is 2.1 MPG less than the peak value of 25.9 MPG achieved in both 1987 and 1988.
		Based on lower average fuel economies and projected longer useful lives, EPA estimates that the new light-duty trucks sold in 1999 will consume, over their lifetimes, almost 60 percent of the fuel used by all of the new light vehicles sold in 1999.

	DJC.COM: SUV popularity lowers overall fuel efficiency, provided by Seattle Daily Journal of Commerce
		Fuel economy for motor vehicles "has been consistently falling since the late 1980s" because of the growing number of light trucks, and for 1999 models, it declined to about where it was in 1980, the report said.
		It said the average fuel economy for new 1999 passenger cars was 28.1 mpg, but the average for light trucks, including SUVs and minivans, was 20.3 mpg.
		As a result, overall fuel economy for passenger vehicles was 23.8 mpg, the lowest since 1980 and six-tenths of a mile per gallon lower than in 1998.

	Annex III - Measuring cooking fuel economy
		Fuel consumption should be measured by weight rather than by volume since it is difficult to measure accurately the volume of a nonuniform fuel such as wood.
		For this measurement, the fuel available to the cook is pre-weighed and the fuel remaining upon the completion of the meal (or the day's meals) is weighed in order to obtain the consumption during cooking.
		Fuel consumption and cooking efficiency tests in the field require the surveyor or researcher to interfere with cooking to some extent.

		This fuel economy is measured by operating the vehicle on a chassis dynamometer using a repeatable driving schedule.
		Vehicle fuel economy can be severely diminished if additional work is required to move a vehicle through snow or water on a highway or if excessive weight is stored in the car.
		Considering all these factors, the fuel economy during urban trips of less than 10 minutes, in cold weather with snowy road conditions can easily be 50 percent lower than operation of the same vehicle in warm weather with dry roads.

	Effectiveness and Impact of Corporate Average Fuel Economy Standards
		With the nation's overall fuel economy slipping for more than a decade, Congress asked the National Academies to study the effects that CAFE standards have had over the past 25 years, as well as effects that potential changes to the program might have.
		To improve a car's fuel economy, one of two things must happen: The efficiency of the powertrain must be increased through new technologies, or the amount of work required by the engine to move the car must be lowered, usually by lessening wind resistance or by reducing the car's size and weight.
		CAFE standards require that the average fuel efficiency for domestic and imported fleets be calculated separately, with domestic fleets being defined as models that are made with at least 75 percent domestic parts.

	Public Citizen \| Fuel Economy (CAFE) - Corporate Average Fuel Economy
		Under the Corporate Average Fuel Economy (CAFE) program, manufacturers’ fleetwide fuel economy averages for cars and light trucks are measured against a federal fuel economy standard for each category of vehicles.
		The fuel economy of the U.S. vehicle fleet peaked in 1988 and has been swiftly declining ever since, due to in large measure to the billions of dollars spent by the auto industry over the past decade in marketing SUVs.
		In the absence of meaningful fuel economy standards, automakers have also been free to use gains in engine efficiency to increase the size and weight of the heaviest, largest vehicles, with devastating consequences for the safety of occupants and others on the road.

	Automobile and Light Truck Fuel Economy: The CAFE Standards
		Between 1976 and 1989, roughly 70% of the improvement in fuel economy was the result of weight reduction, improvements in transmissions and aerodynamics, wider use of front-wheel drive, and use of fuel-injection.
		The legislation would also require that the fuel economy of new vehicles acquired by the federal government exceed the baseline for a particular vehicle class by 3 mpg at the end of FY2003, and 6 mpg by the end of FY2005.
		The fuel economy provisions of H. 2587 were included in H. 4, debated by the House on August 1, 2001.

	Fuel Economy Fraud: Closing the Loopholes that Increase U.S. Oil Dependence
		In 1987, the fuel economy of the new U.S. car and truck fleet reached a peak of nearly 26 miles per gallon.
		This backsliding occurred because fuel economy standards have remained essentially unchanged over the past 20 years and automakers have increasingly exploited loopholes in Congressional and regulatory language.
		This report documents three major loopholes in fuel economy standards and two major cracks in the tax code, and highlights the possibility that a whole new set of loopholes could be created as the Bush administration considers radical changes to the federal fuel economy standards program.

	U.S. Eyes New Fuel Economy Rules - The Car Connection
		More recently the industry's lobbyists have argued raising fuel economy standards could force them to make lighter vehicles that would be more dangerous, limit consumer choices, and hurt sales of domestic automakers that are dependent on sales of trucks and cars.
		By and large, automakers have succeeded in blunting or derailing efforts to boost fuel economy standards and had even hoped that the Bush administration might consider scrapping the fuel-economy standards altogether.
		However, pressure to boost fuel economy standards has increased since the terrorist attacks of 9/11, and the war in Iraq has underscored the U.S. dependence on oil from the Persian Gulf and potentially volatile Central Asia.

	Bush Administration Fuel Economy Proposal Fails To Address Rising Gas Prices
		The new proposal would abandon the concept of a fleet wide fuel economy standard and create a new size-based system that would divide the current light truck fleet into six classes, with each class being determined by wheelbase (length) and track width (width).
		Unfortunately, the proposed gains in fuel economy are likely to be eliminated as a result of the radical overhaul of the current structure.
		Today’s announcement fails to set fuel economy standards for vehicles between 8500 to 10,000 pounds Gross Vehicle Weight Rating (GVWR) - like the Hummer H2, Ford Excursion, and some models of the Chevy Suburban - which are currently exempt from CAFE standards.
