According to the Insurance Institute for Highway Safety (IIHS) the Cobalt receives an overall top score of “Good” for front collisions.[8] However, it receives a “Poor” overall score for side impacts without side curtain airbags,[9] and an “Acceptable” overall score with side curtain airbags.[10] In 2008 side curtain airbags became standard but the Cobalt’s structure remains the same and consequently in structure/safety category of the IIHS’s side impact test the Cobalt receives a “Marginal” score. Side airbags are limited to the curtain type, torso type side airbags are unavailable.[11] According to the IIHS’s injury measurements taken from the side impact test the driver’s torso is given a “Marginal” score.
