WASHINGTON — The 2007 Toyota Camry and 2006 RAV4 small sport utility vehicle earned top marks in front and side crash tests released by the insurance industry.

The Insurance Institute for Highway Safety, reviewing six vehicles, gave the Camry and RAV4 top scores in protecting passengers in a crash. The redesigned Camry has standard curtain-style side air bags to protect passengers' heads and side air bags to protect front seat motorists' midsections.

The 2006 Kia Optima and 2007 Dodge Caliber also earned top scores in frontal tests, but the Caliber had the second-to-lowest score of marginal in side tests.

The Caliber was an improvement upon its past version, the Dodge Neon sedan. In past tests, the Neon was rated poor in side-impact tests.

Among other vehicles tested, the 2006 Lincoln Zephyr and 2005-06 models of the Hyundai Tucson and Kia Sportage received the Institute's second-highest ranking of acceptable in front and side tests.
