In a presentation in Paris on March 1st, Richard Newell the Administrator of the U.S. Energy Information Administration, indicated that by 2035 new light duty vehicle efficiency is projected to reach 40 mpg (miles per gallon). In addition, flex fueled vehicles, mild hybrids, plug-in hybrids, and full hybrids will account for the majority of alternative fueled vehicles sold.
See the presentation below…look specifically at slides 10 and 11.
I was disappointed to see (or I guess not to see) that a very small percentage of new vehicles would be 100% pure electric. With any projection, I guess time will tell. Either way, alternative fueled vehicles will play a role in meeting the new CAFE (Corporate Average Fuel Economy) standards for 2016. The new standards require an average fuel economy standard of 35.5 mpg in 2016. See Whitehouse.gov article on these standards.
