Nearly the End of the Line for S.U.V.’s

Even a federal bailout could not save three of the last remaining plants in the United States still making sport utility vehicles.

Reeling from its financial problems and a collapsing S.U.V. market, General Motors on Tuesday closed its factories in Moraine, Ohio, marking the passing of an era when big S.U.V.’s ruled the road. The moves followed the shutdown last Friday of Chrysler’s factory in Newark, Del., which produced full-size S.U.V.’s.
