Chart: True MPG by Manufacturer
According to the data collected by, the miles per gallon average for all vehicles sold in October 2011 is expected to be 22.2. That may not sound like much when compared to the kind of numbers that are tossed around when talking about hybrids, newer diesels or even the latest generation of efficient small sedans, but it's a small step in the right direction from the 21.5 mpg delivered by vehicles sold a year ago. Looked at over the short term, this also marks the fourth month in a row when the mpg has increased.

The biggest gainers were Hyundai and Ford, whose numbers were up for the same reason that the overall numbers rose: an increase in the sales of small cars. Ford's mpg numbers rose from 20.1 in October 2010 to 21.3 in that same month in 2011. Hyundai kept its place at the top of the charts with a move from 25.7 to 26.8.

TrueMPG is calculated using sales by manufacturer and model, the EPA estimates, and the trim level for vehicles sold.
