America’s new cars are more fuel-efficient than ever before
The 1990s-style thirst for power that gave rise to America’s fleet of gas-guzzling SUVs is being replaced by a hunger for fuel-efficient cars, helping auto manufacturers in 2012 beat their previous record for overall gas mileage.
The average model-year 2012 vehicle got 23.6 miles per gallon, according to a new report from the EPA. OK, that’s still pretty lame — but it’s 1.2 mpg better than the previous year, the second-largest annual increase in history.

“More consumers value fuel economy than in the past,” Christopher Grundler, director of the EPA’s office of Transportation and Air Quality, told the AP.
The average new car last year had 222 horsepower. That’s a helluva lot of horses, but nonetheless a reduction of eight relative to 2011, according to the report. That helped improve overall mileage, as did a 150-pound reduction in the weight of the average car.
Here are more report highlights from EPA:
Fuel economy has now increased in seven of the last eight years. …
The large fuel economy improvement in model year 2012 is consistent with longer-term trends. … While EPA does not yet have final data for model year 2013, preliminary projections are that fuel economy will rise by 0.4 mpg, and carbon dioxide emissions will decrease by 6 grams per mile in 2013.
EPA … attributes much of the recent improvement to the rapid adoption of more efficient technologies such as gasoline direct injection engines, turbochargers, and advanced transmissions.
Consumers have many more high fuel economy choices due to these and other technologies, such as hybrid, diesel, electric, and plug-in hybrid electric vehicles. Consumers can choose from five times more car models with a combined city/highway fuel economy of 30 mpg or more, and from twice as many SUVs that achieve 25 mpg or more, compared to just five years ago.
Nearly every major automaker produced vehicles in 2012 that were more efficient than its models from the year before. Mazda now has the most efficient fleet, while Chrysler is the biggest laggard.
