Univ. of Delaware Researchers Conclude Cash for Clunkers Cost Exceeded Benefit

Green Car Congress

Assuming 12,000 as the average miles driven per year and using the average mpg of the retired vehicles (15.8 mpg) and the newly purchased vehicles (25.0), they calculated that the program cut gasoline consumption by some 280 gallons per year per vehicle.

ACEEE ranks i-MiEV as “Greenest” car in US, Civic Natural Gas ties for second with LEAF

Green Car Congress

Highly efficient conventional gasoline vehicles also continue to have a presence on the “Greenest” list, claiming three of the top twelve spots. Vehicles are analyzed on the basis of a “Green Score,” a singular measure that incorporates unhealthy tailpipe emissions, fuel consumption, and emissions of gases that contribute to climate change.
