Although the U.S. and Europe are meandering down the same road to fuel efficiency, they’re driving in different lanes. Hybrids, which have caught on among a certain set on this side of the Atlantic, are just now hitting Europe. On the other hand, thrifty Europeans have embraced diesel — in the form of the teeny-tiny, 60-mpg “smart car” — and are sending some this way. Of course, knowing American proclivities, they’ve made an SUV version called — and I audibly groan here — “formore.”

In other green car news, the mayor of Fort Wayne, Ind., is converting the city’s trucks to biodiesel and buying hybrid cars. Hmm … will they be red or blue?
