Gas guzzler graveyard

High pump prices are hitting big SUVs hard and shrinking their numbers. Here's a look at a few former kings of the road.

Big SUVs used to rule the American road. But now, like big cars with tail fins in the '50s or muscle cars in the '60s, full-size SUVs may have seen their day.

High gas prices have sent consumers in search of more fuel-efficient alternatives, such as car-based crossovers, and that's meant hard times for these brawny vehicles.
