SANTA MONICA, Calif. — April 22, 2010 — An analysis of the best selling vehicles in 2010 and 2005 reflects a major shift towards fuel efficiency, according to, the premier online resource for automotive information.

The top five best-selling vehicle segments generally account for just under two thirds of total vehicle sales. Today's best sellers earn an average of 20.4 miles per gallon, while the 2005 group earned an average of 18.2 mpg.

"There will come a day in the not-so-distant future when a comparison of fuel efficiency improvements from five years earlier will be laughable," remarked Edmunds' Editor John O'Dell. "There is much promise reflected in the upcoming introductions of mainstream electric vehicles like as the Chevy Volt and the Nissan Leaf."

In 2005, large trucks were the most popular purchases among new vehicle buyers, and the segment averaged 14.5 miles per gallon. Today, midsize cars sell at the fastest rate and earn an average 22.0 miles per gallon.
