New crash tests of midsize cars: protection in side impacts improves, but most cars tested still afford marginal or poor protection in rear crashes

Occupant protection in side impacts of midsize cars is improving as automakers introduce safer designs and add side airbags as standard equipment. The Insurance Institute for Highway Safety recently completed front, side, and rear tests of seven 2008 model midsize cars, both moderately priced and luxury: Chevrolet Malibu, Dodge Avenger, Infiniti G35, Kia Optima, Mitsubishi Galant, Nissan Altima, and Saturn Aura.
