WASHINGTON (AP) — The government says new cars and trucks averaged 24.3 miles per gallon last year, marking no improvement.
The Environmental Protection Agency says fuel economy stayed flat as technological advancements in automotive engines and transmissions were offset by a resurgent demand for larger vehicles.
EPA originally reported the 2013 average at 24.1 miles per gallon, but later revised that figure upward by two-tenths of a mile per gallon. Falling gas prices and consumers' rekindled love of SUVs could endanger future fuel economy gains.
The EPA's calculations are based on cars and trucks produced for sale in the U.S. each model year.
Officials predict slow growth for 2015. Automakers still expect to meet federal standards requiring a fleet-wide average of 54.5 miles per gallon by 2025.
