About the original moderate overlap front test

Tested vehicle: 2005 Chevrolet Cobalt 4-door with optional front and rear head curtain airbags
Rating applies to 2010 models

The Chevrolet Cobalt was introduced in the 2005 model year as a replacement for the Cavalier and discontinued after the 2010 model year.

Two tests of a Cobalt were conducted, one with an optional side airbag for the driver and rear passenger, and one without. These vehicles are rated separately, except that the structural ratings for both vehicles are based on both tests.

In the 2008-09 model years, the side airbags were made standard, except in cars sold to fleet buyers that could still be ordered without side airbags. Caution: This means that when fleet vehicles without side airbags are eventually sold, they will be available to retail purchasers. For the 2010 models, side airbags were made standard for retail and fleet buyers.
