US vehicle fleet fuel efficiency fell in 2019 to 24.9 mpg : EPA
The US vehicle fleet's fuel efficiency in the 2019 model year fell to 24.9 miles per gallon (mpg) as more Americans bought larger sport utility vehicles instead of cars, the Environmental Protection Agency said on Wednesday.
The EPA said the fuel economy of the US fleet fell by 0.2 mpg and most manufacturers are using banked credits to meet current compliance requirements. It said fuel economy and emissions have improved in 12 out of the 15 years since the 2004 model year vehicle fleet average of 19.3 mpg.

General Motors Co and Fiat Chrysler Automobiles NV (FCA) both saw fleetwide fuel economy fall 0.5 mpg in the 2019 model year, with FCA at 21.2 mpg and GM at 22.5 mpg. Ford Motor Co rose 0.1 mpg to 22.5 mpg.
The shift to larger vehicles was the biggest factor hurting fuel economy. In 2019, 44% of the fleet were cars and 56% were light-duty trucks, a category that includes SUVs, the highest percentage of trucks on record. SUVs alone account for almost 50% of US vehicle production.
The EPA also said average vehicle weight and horsepower hit records in the 2019 and were on place to rise again in 2020. Horsepower is up 79% since 1975 for all vehicles.
