Gas Mileage

  • Gas pump

    It's been clear that under the Trump administration, the NHTSA and EPA plan to roll back linked fuel-economy rules and emission limits on new vehicles. Now a possible justification that will be used has emerged—and it's not the one many advocates had expected. According to a Bloomberg report on Monday, the fuel-economy proposal due March 30 may lower the requirements because the agency will claim that will make new cars safer.

  • Ram 1500 Plug-In Hybrid pickup truck and Chrysler Town & Country plug-in hybrid minivan, April 2012

    U.S. car buyers have increasingly ignored passenger sedans and hatchbacks and replaced them with utility vehicles of various sorts, and that's a trend that shows no sign of abating. One reason is that crossovers and SUVs now get better fuel economy than they did 10 years ago, when owning one imposed a significant hit in gasoline costs every week. Gasoline has stayed cheap, and so light utility vehicles are eating significantly into sales of sedans.
