Improving Automobile Efficiency (broadcast Friday, December 7th, 2007)

US DOE

Energy legislation currently moving through Congress could result in an increase in fuel efficiency standards for the U.S. auto fleet. Current law sets the 'Corporate Average Fuel Economy,' or CAFE, at 27.5 miles per gallon for cars and 22.2 miles per gallon for light trucks, a category that includes many sport utility vehicles. The new legislation would somewhat change the way CAFE is calculated, basing the measurement in part on the size of the vehicles involved. The overall average efficiency of all vehicles sold in the U.S. would be set at 35 miles per gallon by 2020. The White House has said it plans to veto the legislation.

In this segment, Ira and guests talk about the energy legislation, and about research into improving the fuel efficiency of cars and trucks. Is it time for a new approach entirely? Teachers, find more information about using Science Friday as a classroom resource in the Kids' Connection.
