The Obama administration is suggesting a fuel-economy standard of 56.2 miles per gallon average for an automaker’s whole fleet by 2025, boosting the price of a new vehicle at least $2,100, the government calculates.
That rating in EPA testing, converted for real-world driving, would translate to a window-sticker rating of about 37 mpg for combined city/highway driving. The best gasoline-electric hybrids already beat that, and some gas-only small cars are close, rated 33 or 34 mpg in city/highway driving.
