Obama Tells EPA To Set Next Heavy-Duty Truck Fuel-Efficiency Rule
The Obama Administration wants stricter truck fuel-economy rules to replace the current standards, which expire in 2018.

One of the best ways to save a lot of fuel is to improve the efficiency of the lowest-mileage vehicles on the roads. Those include semis, which often get no more than 2 or 3 miles per gallon of diesel fuel. Their huge diesel engines must put out massive torque to tow one, two, or even three trailers, and the resulting assembly has some of the worst aerodynamic drag of anything on the road. Since 2008, an entrepreurial startup called ATDynamics has been selling its $2,000 "Trailer Tail," which mounts on the rearmost trailer to smooth the airflow coming off the back, reducing drag and improving...
