U.S. seeks 5 percent annual fuel-economy gains through 2016

The Obama administration today proposed gasoline mileage and greenhouse-gas pollution standards for new vehicles for model years 2012 to 2015, filling in the blanks for manufacturers en route to a 35.5 mpg national target in 2016. The Transportation Department and EPA proposal calls for fuel economy to increase by about 5 percent each year, starting from an average of 27.3 mpg for the 2011 model year, the agencies said in a statement.

NHTSA says that designing the vehicles to make noise at speeds below 18 mph would prevent about 2,800 injuries over the life of each model year of vehicles.
