The average mileage for new vehicles rose from 21.4 miles per gallon in June to 22.1 mpg in July. That may not sound like much, but it's the highest mileage researchers at the University of Michigan have seen since the Environmental Protection Agency reconfigured mileage estimates in October 2007. It's also the biggest one-month jump.
Study co-author Michael Sivak noted the improvement came even as gas prices fell and unemployment levels shrank somewhat. Normally, those factors lead to the purchase of more gas guzzlers.

That's because the trade-in rebate program only got going late in July.
