Fuel Savings * USA - Scientists quantify one
USA -eTrucker, by Max Kvidera -24 Oct 2008: -- By using off the shelf technology, owners of long range tractor trailers could reduce fuel consumption per unit up to 12 percent annually, or 2,000 gallons, reduce emissions and realize a profit of as much as $30,000 per truck over the first eight years of ownership, says a study released today by the Union of Concerned Scientists... Retrofitting used tractors and trailers as old as 12 years with a full package of fuel-saving technologies could still produce unidentified net savings for individual owners, the report said... For fleet owners with an average of 2.5 trailers per tractor, a full technology package could yield savings for equipment up to 6 years old... The report used an average fuel price of $3.24 over the past two years and estimated that tractor-trailers ran about 130,000 miles annually and achieved fuel economy of 6 to 6.5 mpg... A full fuel-efficient technology package could include aerodynamic trucks with a sloped hood and full roof fairing, wide-single tires, trailer side skirts or side panels that cover gaps between wheels and rear-trailer fairings, the report said...
