Tell Ford to improve gas mileage! (english)
01 May 2003
Cars and light trucks guzzle 40% of U.S. oil and emit 20% of the nation's carbon dioxide (CO2) pollution. Each gallon of gasoline burned pumps 28 pounds of CO2 into the atmosphere-19 from the tailpipe and nine pounds from upstream refining, transporting and refueling.

Mr William C Ford

Tell Ford Motors to get more out of a gallon of gas.
----------------------------------------------------------------------------
Subject: Ford vehicles should average 40 miles/gallon.

It's time to free America from its 8-million-barrel-a-day oil habit.
As chairman of Ford, you have a responsibility to improve fuel
economy. You can help break the grip of oil producing countries;
instead, your company is fighting new standards to require
better gas mileage.

Detroit is not being asked to stop making SUVs, but to use
technology and American know-how to improve fuel economy.

Please publicly commit to make your vehicles average 40 miles
per gallon. Start improving fuel economy by putting the Freedom
Option Package of technologies into your five top-selling
vehicles. By turning gas-guzzlers into responsible vehicles,
you can help reduce both America's dependence on oil and
the threat of global warming.

Sincerely,

Your Name
Your Address

BACKGROUND INFO

The biggest single step the United States can take to curb global warming and ensure a safe energy future for America is to adopt stronger automotive fuel-economy standards for cars and light trucks. Congress passed current Corporate Average Fuel Economy (CAFE) standards in 1975. They have proven to be the most successful energy saving measure Congress has ever adopted, saving three million barrels of oil per day. The standards require that new cars average 27.5 miles per gallon (mpg) and light trucks average 20.7 mpg. Automakers can produce vehicles with lower mileage as long as enough vehicles exceed the standard. Since auto makers achieved the standards in the 1980s, however, average fuel-economy levels have been in decline.The average fuel economy of new vehicles sold in 2000 sank to its lowest point since 1980.

Cars and light trucks guzzle 40% of U.S. oil and emit 20% of the nation's carbon dioxide (CO2) pollution. Each gallon of gasoline burned pumps 28 pounds of CO2 into the atmosphere-19 from the tailpipe and nine pounds from upstream refining, transporting and refueling. The average car emits about 70 tons over its lifetime - the average SUV around 100 tons. America's automobiles produce more global-warming pollution than all sources in Great Britain combined!

Updated CAFE standards could save an additional three million barrels of oil each day when fully implemented. New standards of 45 mpg for cars and 34 mpg for light trucks would cut CO2 pollution by 600 million tons and save consumers at least $45 billion each year at the pump. The U.S. is the world's largest emitter of CO2 and must take the lead in reducing this pollution-particularly by automobiles.

QUESTION AND ANSWER

Q: Can we improve fuel economy without sacrificing safety?

A: Absolutely. Long-time safety advocates such as the Center for Auto Safety and Ralph Nader support increasing the CAFE standard to 45 miles per gallon and point out that we can do so safely. In its report on auto-motive fuel economy, the National Academy of Sciences agreed that improvements in fuel economy need not impair safety: "improved design and the incorporation of new technology can enhance both crash - avoidance and crash-worthiness potential,while improving fuel economy. In fact, the rate of traffic fatalities fell 50% over the same period that CAFE doubled car-fuel economy."

The auto manufacturers claim they can only achieve higher CAFE standards by making "mini-cars." But they said the same thing in 1974 when a Ford spokesperson testified before Congress that a 27.5 mpg standard would result in a "Ford product line consisting of either all Pinto-sized vehicles or some mix of vehicles ranging from a sub-sub-compact to perhaps a Maverick." Obviously, they were wrong then and they are wrong again today.

CAFE improvements would require increases in the average fuel economy of the fleet of automobiles, not every individual vehicle. Manufacturers could use existing technologies (see below) to increase fuel economy, rather than making " Pintos and Mavericks."

Q: What technologies are currently available that will help get the average new
automobile to 45 mpg?

A: Technology accounted for 86% of the fueleconomy improvements between 1975 and the late 1980s. Greater use of technology will again be key to increasing fuel economy and saving oil. Gasoline-electric hybrid engines can be used to achieve significant improvements in fuel economy. Honda's Insight 2-seater travels 70 mpg and the Toyota Prius 5-passenger car gets 55 mpg. Ford has plans for a 40 mpg hybrid SUV in 2003. A hybrid combines an electric motor that does not need to be plugged in with a clean gas-powered engine, refillable at any gas station. The gasoline engine generates electricity for the electric motor, and the energy typically lost to braking is also directed to recharge the batteries. Other existing technologies are readily available to improve fuel economy. According to a 1992 National Academy of Sciences report, "most of these technologies have reached only a fraction of their potential application in vehicles sold in the U.S. " These technologies, which still haven't been implemented, in addition to hybrid engines, can be used to improve fuel economy.

1. Changing an engine from two to four valves per cylinder improves its fuel economy by over 5%. Engines with four valves per cylinder deliver fuel and oxygen to their engines more efficiently, and increase fuel economy.

2. Variable valve timing (VVT) adjusts the air flow at different engine speeds to the optimum level, improving horsepower and fuel economy by about 12%. Adding leanburn technology, which introduces more air than is needed to the combustion chamber, to engines with VVT can provide further fuel-economy gains. Honda's 1994 Civic VX with a VTEC-E lean-burn engine was 44% more efficient than that year's Civic DX without the lean-burn engine.

3. Electronically controlled gear shifting, automatic transmissions with five speeds rather than three or four speeds, and continuously variable transmissions, such as the ones found in Honda's Civic HX and Toyota's Prius, enable cars to operate at optimal efficiency more of the time, wasting less fuel.

4. High-strength, lightweight materials, like those found in Saturns and some Audi models, can reduce the load the engine carries without compromising safety. The Congressional Office of Technology Assessment found that 35 pounds of composite plastics or 45 pounds of aluminum can be as strong as 100 pounds of steel. Every 10% reduction in weight yields a 6.6% average improvement in fuel economy.

5. Front-wheel-drive vehicles don't have bulky drive shafts, so they are lighter and require less fuel to operate. Automakers could shift most of the millions of rear-wheel-drive vehicles sold annually in the U.S. to front-wheel-drive and improve the fuel economy of each by 12.5%.

* Better aerodynamic designs, like that of the Ford Taurus, can cut down on wind resistance and improve fuel economy by 3 to 5%.

Q: The auto industry says higher fuel economy will cost jobs. Is this true?

A: No. A study by the American Council for an Energy Efficient Economy (ACEEE) shows that higher fuel economy will actually create jobs. Although some sectors of the economy, such as the oil industry, will experience losses, ACEEE estimates the auto industry alone will gain 47,000 new jobs. They project that money saved at the gas pump will be reinvestedd throughout the economy, creating a net increase of 244,000 new jobs nation wide. The real danger to auto industry jobs is U.S. automakers' lack of leadership in developing new technologies. While Japanese and European car makers are putting lean-burn engines, continuously variable transmissions, and other efficiency technologies into their cars, American automakers continue to produce primitive, inefficient designs. U.S. fuel economy is actually in decline. During recent years, each Big 3 Automaker has failed to meet the current CAFE standards.

Q: Will truck owners still be able to buy the vehicles they need under tighter CAFÉ standards?

A: Yes. According to the Union of Concerned Scientists, technology can make today's best selling SUV, the 19 mpg Ford Explorer, a 34 mpg vehicle. Improved engine, aerodynamics, and transmission along with high-strength, light-weight steel will make the difference. And, this technology will cost $935 and save around $5500 at the pump, based on $1.50 per gallon. The fuel economy of pickup trucks can also be vastly improved with technology at even less cost. The fuel-economy standards for light trucks have virtually stagnated for 20 years. Light trucks are now half of all new vehicles sold compared to 20% in 1975. The loophole in the law that lets these vehicles meet a lower 20.7 mpg standard means an additional 18.4 billion gallons of gasoline burned each year and 237 million tons of global-warming pollution emitted into the atmosphere.
