New Standards Would Increase Gas Mileage 25% by 2015

These new fuel economy benchmarks would save billions of gallons of gas and billions of dollars in fuel costs for drivers.

    Given impending increases to CAFE (corporate average fuel economy) standards, all cars will become more fuel-efficient, and there will be more superefficient models, such as the Toyota Yaris. The question is how high will regulators push the new CAFE benchmarks?

The U.S. Department of Transportation (DOT) proposed new fuel economy standards on April 22 that will result in a 25 percent increase in fuel economy by 2015. The proposed new Corporate Average Fuel Economy (CAFE) standards apply to cars and light trucks — pickups, vans, and SUVs — starting with vehicles in model year 2011, most of which will go on sale in late 2010. The proposed standards increase fuel economy by 4.5 percent per year for five years, ending with model year 2015. For passenger cars, the proposal would increase fuel economy from the current 27.5 miles per gallon (mpg) to 35.7 mpg by 2015. For light trucks, the proposal calls for increases from 23.5 mpg in 2010 to 28.6 mpg in 2015.

The proposed standards are the first step in implementing a 40 percent increase in fuel economy by 2020, as mandated by the Energy Independence and Security Act of 2007. See the DOT press release and the article from this newsletter on the energy act.

If the new standards are put in place as proposed, they will save nearly 55 billion gallons of fuel while cutting roughly 521 million metric tons of carbon dioxide emissions. Drivers that buy the new vehicles covered by the standards will collectively save more than $100 billion in fuel costs over the lifetime of the vehicles. The DOT's National Highway Traffic Safety Administration (NHTSA) will accept comments on the proposed standards for 60 days after their publication in the Federal Register.

In addition, the NHTSA is preparing an Environmental Impact Statement (EIS) to address the potential environmental impacts of the proposed standards and is seeking suggestions on the environmental issues and reasonable alternatives to be addressed in the EIS. The NHTSA is also requesting information from automakers on how they plan to meet the proposed rules. See the full proposal and related documents on the NHTSA Web site.

Although the new standards will mandate increases in fuel economy starting in late 2010, the current record-high prices for gasoline and diesel fuel are causing consumers to emphasize fuel economy now, and that shift in mindset is already influencing automakers' production plans. On April 28, General Motors Corporation (GM) announced that it will cut production of its full-size trucks by eliminating one production shift at four North American assembly plants: three that build full-size pickups and one that builds SUVs. The changes will cause GM to produce 138,000 fewer full-size trucks this year. On April 29, GM launched a new edition of its Chevrolet Cobalt, called the XFE for "Xtra Fuel Economy." Available in manual-transmission versions of both the sedan and the coupe, the Cobalt XFE will achieve an estimated 25 mpg in the city and 36 mpg on the highway through the combination of a revised engine calibration, low-rolling-resistance tires, and a higher gear ratio in the fifth gear. The Chevrolet Cobalt XFE is on sale now.

The American Automobile Association's "Fuel Gauge Report" listed new record highs for motor fuels on Tuesday, with the national average for regular gasoline hitting $3.607 per gallon and diesel fuel hitting $4.244 per gallon. See the GM press releases on the production cuts and the Cobalt XFE, and for the latest fuel prices, see the Fuel Gauge Report.

If a vehicle is getting 25mpg now, a 25% increase would move that to 31.25mpg. A very pathetic increase. Too little, too late! Our 97 Saturn gets about 37mpg with ethanol added and 42mpg without(that's another story). I had a 1985 Chevy Sprint 3 cylinder that got 55mpg on the highway at 55 mph. We have regressed folks. The new version of the Jeep that I now own (97)has a curb weight of 1000 pounds more than my vehicle. Mine is a Grand Cherokee with all the bells and whistles with a V-8. Electric vehicles are the way to go! The motors go at least 300,000 miles before they need anything and then it might be just a couple of bearings and back on the road. No computers to control an engine and no fuel to burn and the batteries are recycleable. If they come up with a better battery you just replace yours the next time you swap batteries and you get more efficient. Let see you do that by changing the fuel in your tank! Do yourselves a favor and see the videos "Crude Awakenings" and "Inconvenient Truth" and "The End of the Suburbs".
