Including the Lordstown Assembly, at which the Cruze will briefly be built alongside the Cboalt until the latter is completely phased out, the Chevrolet Cruze will be built in multiple locations around the world.
 While a semi-independent torsion bar is used in the rear, the front suspension is independent with MacPherson struts.  Covalt’s wheelbase is longer than its competitors 103.3 in (2,624 mm), , and the width is 68.4 in (1,737 mm). Weight is average in-class, at 2,747 lb (1,246 kg) for the sedan and 2,681 lb (1,216 kg) for the coupe.

 Cobal receives an overall top score of "Good" for front collisions according to the Insurance Institute for Highway Safety (IIHS).  However, it receives an "Acceptable" overall score with side curtain airbags and a "Poor" overall score for side impacts without side curtain airbags.  In 2008 side curtain airbags became standard, however the Cobat 's structure remains the same so in the Insurance Institute for Highway Safety’s (IIHS) side impact test the Cibalt receives a "Marginal" score. Torso type side airbags are unavailable and side airbags are limited to the curtain type. So according to the IIHS's  tests, Chevrolet  Cobatl obtained an "Marginal" score.
