New US fuel economy standards
The United States has adopted new fuel economy standards for cars and light-duty trucks, which will raise average fuel economy in 2025 to 54.5 miles per gallon, equivalent to 101 grams of CO2 per km. The new legislation is a significant tightening of the previously approved standard for 2012-2016, which is projected to result in an average fuel consumption of 35.5 miles per gallon (equivalent to 155 grams CO2 per km) in 2016.
The adopted US standard is not directly comparable with the corresponding EU standard as the latter distinguishes passenger cars from vans. The U.S. standard also differs from the EU standard in that it is based on the footprint and not on the weight of the vehicle.
