DETROIT (Reuters) - Ford Motor Co is assembling a plan to retool its North American truck plants to build cars in a bid to keep up with changing consumer demand in the United States, the Detroit News reported on Wednesday.

The No. 2 U.S. automaker would revamp some of its North American plants to produce vehicles currently built in Europe, where it is a leader in the small-car segment, the paper reported, citing people familiar with the company's plans.

Ford is also reviewing its entire product pipeline in North America to accelerate the introduction of more fuel-efficient cars and build more vehicles on fewer platforms, according to the report.

Details of the plan are expected to be announced in July, it said.

A Ford spokesperson was not immediately available for comment.

Ford's U.S. vehicle sales plunged 12 percent in the first five months of 2008 from a year earlier as record gasoline prices depressed sales of gas-thirsty trucks and large SUVs.

Last month, Ford dropped its long-standing goal of returning to profitability in 2009, saying the shift in consumer demand toward fuel-efficient cars and crossovers and away from trucks and SUVs is permanent.
