Ford Motor Co. led all automakers for the second year in a row with six 2010-model top safety picks from the Insurance Institute for Highway Safety, including four from Volvo, a brand that's being sold. Subaru and Volkswagen AG finished next with five qualifying vehicles, and Chrysler Group had four. Offerings from General Motors, Mercedes-Benz, Honda, Kia and Nissan also made the list.

The nonprofit insurance group, funded by auto insurers, tightened its top pick criteria for the second time since it started the award for the 2006 model year.

This year vehicles must have “good” ratings in the institute's rollover testing. Getting that rate requires doubling the roof strength required by the U.S. government, the group said in a statement.

That adds to existing requirements for receiving the “good” label in front, side and rear crashes and having electronic stability control.

Toyota was the only automaker among the six biggest in the United States that didn't have a winner. Before this year, Toyota, the world's top-producing automaker, had top safety picks in every year but 2007. The Camry almost qualified, the insurance group said. But it received a “marginal” rating in a rear crash test because the seats and headrests provided less than desirable protection against whiplash.
