Fuel efficiency gains for new vehicles sold in the US were in a bit of a holding pattern last month, according to a new report from TrueCar. Fleetwide fuel efficiency for new US light-duty vehicles in September rose 5.5 percent compared to 2011 figures, but remained the same as August 2012 figures.

In September, new cars got an average of 23.2 miles per gallon, up from an even 22 miles per gallon in September 2011. Through the first three quarters of 2012, US fleetwide new-vehicle fuel economy has been up 5.9 percent from 2011. Looking at individual automaker figures, Toyota showed the biggest year-over-year fuel efficiency gain (with a 1.4 percent increase), while Honda and General Motors both made 1.1 percent advances. On the flipside, Volkswagen's fuel efficiency gains were the lowest among the automakers tested, rising just 0.2 percent from a year ago. More details available below.

TrueMPGTM is an easy-to-understand and objective way to comprehend monthly fuel economy averages by brand, manufacturer, origin and vehicle segments using Environmental Protection Agency ("EPA") ratings based on estimated and/or actual monthly automotive sales-weighted data. TrueCar.com seeks to provide transparency and truth in average fuel economy, providing an alternative view to Corporate Average Fuel Economy ("CAFE") ratings that can be confusing and misleading. TrueMPGTM helps keep in perspective what each manufacturer's average miles per gallon per car sold, computed monthly and annually, by using the EPA's window sticker ratings.

TrueMPGTM computes monthly average fuel economy by brand, manufacturer, origin and vehicle segments by using actual sales data or forecasted sales data for the current month. Calculations start at the trim level, taking into account EPA fuel economy data including engine size and drivetrain that affect a vehicle's MPG ratings; the sales share from each trim level is then calculated to create an average for each model. Brand level data is calculated by the sales share of each model and the manufacturer data is then based on the share of each brand, providing an accurate and completely data driven picture of actual measured MPGs in the market place. TrueCar utilizes the EPA's average fuel economy rating using 45 percent highway and 55 percent city driving behavior.
