    While it's far from the best or mist accurate testing method, the one thing CAFE has going for it is the unilateral consistency. For the most part, you're comparing apples when you compare EPA numbers across manufacturers. Yes, Hyundai/Kia just got caught cheating, and there's no legit way to test the "fuel economy" of an electric vehicle, but for 99% of the buyers out there, it's a tool they can actually use.

    "The average fuel economy of new vehicles sold in the U.S. last month was 25.4 miles per gallon — an increase of 5.3 mpg since October 2007. "

    Putting challenges in front of automakers has, historically, produced a much better automobile.

    The average fuel economy of cars, light trucks, vans and SUVs purchased in the United States in May was 25.6 mpg, a 0.4 mpg improvement over the previous month, according to the University of Michigan Transportation Research Institute.

    This marks the highest average mpg capability ever, topping the previous record -- 25.2 mpg in March -- by 0.2 mpg, the research institute said in a statement this week. The average is up 5.5 mpg from October 2007, the first full month of monitoring by the institute.

    Average Fuel Economy for New Cars Holds Steady at 25.3 MPG in October

    "The unchanged average fuel economy is likely a net consequence of two opposing trends: less demand for fuel-efficient vehicles because of the decreasing price of gasoline, and improved fuel economy of 2015 model year vehicles compared to 2014 model year vehicles."

    In California, when the new law is signed by the Governor, the standard will be 35mpg. Hybrids can do that as well as electric. Technology will advance, the goal is achievable. Yes, Diesel can do it now, but they will not allow dirty Diesel in 15 years, so better count on the hybrids.

    Progress toward 2025 goals is good, but slowly recently:

    "The average unadjusted fuel economy of U.S. light vehicles from 2014 needs to increase 57% to meet 2025 goals, according to the new WardsAuto CAFE Performance Index, based on EPA and NHTSA standards.

    The annual rate of improvement will need to be about 4% to meet those 2025 goals. Small and midsize cars are closest to their requirements, while large cars and SUVs need the most development.

    The WardsAuto Fuel Economy Index showed new light vehicles sold in the U.S. had an average window-sticker fuel-economy rating of 25.4 mpg (9.3 L/100 km) through the first-half of 2015, just 1.3% above like-2014. The results for calendar-year 2014, 25.0 mpg (9.4 L/100 km), were 2.2% higher than the prior year.

    A sharp drop in the average price of gasoline moved some consumers to larger, less-efficient vehicle types, thus slowing the rate of progress. These trends started last year and continue to hinder growth for 2015.

    Improvement in the index results was due to the increasing availability of more-efficient vehicles. While dealing with consumer demand for traditionally less-efficient cars and trucks, automakers are using smaller engines and higher-speed transmissions to reach CAFE standards. Four-cylinder engines powered 52.2% of U.S. LVs in model year ’14. Eight-speed automatics and CVTs have increased share at the expense of 4-, 5-, 6- and 7-speed units.

    Light trucks accounted for 52.6% of indexed sales in 2014, above cars for the second consecutive year. The rating for cars improved 2.9% from 2013 to 29.2 mpg (8.1 L/100 km). Light trucks averaged 21.1 mpg (11.1 L/100 km), up 2.8%. All eight WardsAuto vehicle segments exceeded previous index highs in 2014...."
