Two previous tests of a 2004 Chevrolet Malibu were conducted, one with an optional side curtain airbag for the driver and rear passenger, and one without. Beginning with 2005 models, side airbags designed to protect drivers' and front passengers' torsos were added to the optional side curtain airbags previously available.
The three tested vehicles are rated separately, except that structural ratings for the vehicles are based on the two previous tests plus the latest test. Also, the rear passenger injury and head protection ratings are based on the two tests with side airbags.
Please note that roadtests.com provides the test of the model equipped WITH all optional side-impact airbags only. In the test without these airbags, the Malibu fared much worse, earning an overall "Poor" evaluation due to strong head, neck, and torso-injuries on the driver's side. Roadtests.com would thus like to encourage buyers to specify the optional side-impact airbags upon purchase.
