Even without a Cash for Clunkers $2 billion extension locked in place by the Senate, the U.S. government bean counters are crediting the auto incentive for moving more than 180,000 vehicles off dealer lots. The big winner so far is Toyota, knocking Ford's Focus off the top-selling vehicle spot with its economy-oriented Corolla sedan.

According to the numbers, more than 80 percent of the traded-in vehicles were light trucks (including SUVs, pickups, and vans), and 59 percent of the purchases are passenger cars... meaning the program is successfully replacing those thirsty vehicles with a class that is a bit more efficient.

The list of top-10 most traded-in vehicles is chock-full of domestic trucks. The soon-to-be-euthanized victims include five light trucks by Ford, three Jeep and Dodge brands, and two Chevys. And lastly, for those keeping track of the decimal points, the new vehicles being sold under the program earn an average 25.3 mpg, while the condemned only brought an 18.5 mpg average to the party.
