(August 9, 2011) SANTA MONICA, Calif. (PRNewswire) — TrueCar.com today provided actual fuel economy numbers from June light vehicle auto sales that indicate TrueMPG will increase to 21.6 mpg in July 2011 compared to 21.4 mpg in July 2010, but remain flat from June 2011 at 21.6 mpg.

"In July, a balanced mix of cars and trucks were purchased, keeping the overall fuel economy of new vehicles sold flat compared to June," said Jesse Toprak, Vice President of Industry Trends and Insights at TrueCar.com. "Looking into the second half of the year, TrueMPG should decrease as consumers tend to purchase larger vehicles during the winter months."
