    FOTW #1131: Average Fuel Economy for Model Year 2019 Light-Duty Vehicles Was 95% Better than Model Year 1975

    Originally posted by the Department of Energy Office of Energy Efficiency and Renewable Energy | Original Article

    The average production-weighted fuel economy for all new light-duty vehicles in model year (MY) 2019 was 95% better than in MY 1975, while average horsepower was 78% higher and weight was 1% higher. From the late 1980s to the mid-2000s, fuel economy generally declined while horsepower and weight increased. Since 2004, due to technical innovations, fuel economy and horsepower have increased while vehicle weight has stayed about the same.

    Note: Data for 2019 are preliminary. All data are production weighted.
