Fuel economy and the electrified vehicle dominate the show.
But with current fuel pricing — a barrel of oil skidded to $35 last week — alternative-energy cars are going to have to wait to catch the American mainstream.
"At $1.50 a gallon, the American public is not willing to pay for fuel-saving technology," said General Motors Vice Chairman Bob Lutz. AutoNation Inc. CEO Mike Jackson said last week he could give away a Toyota Prius hybrid right now — in contrast to last summer, when the Prius had a waiting list of buyers.
But automakers face increased concerns about global warming, sharply higher federal fuel economy rules and large loans from the U.S. government. So electric and hybrid cars are hot, at least in the sense that almost every major automaker has at least one on display.
Here's a look at some hits and misses from the Detroit show — hybrids, electrics, diesels and traditional gasoline-powered cars and trucks.
