A new energy law calls for the fleet wide average of new cars and trucks to reach 35 miles per gallon by the year 2020. The current rule calls for 27.5 miles per gallon for cars. SUVs, pickup trucks and vans need to get 22.5 miles per gallon. Transportation Secretary Mary Peters announced this proposal which is expected to be finalized before President Bush leaves office.
