About the original moderate overlap front test

Tested vehicle: 2009 Chevrolet Cobalt LT 2-door with standard front and rear head curtain airbags
Rating applies to 2009-10 models built after May 2009

The Chevrolet Cobalt was introduced in the 2005 model year, and the Pontiac G5 (available only as a 2-door) was introduced in the 2007 model year. Beginning with 2008 models, side airbags were made standard (they were optional in 2005-07 models). The Pontiac G5 was discontinued after the 2009 model year and the Cobalt after the 2010 model year.

Starting with 2009 models manufactured after May 2009, the side curtain airbags of the 2-door models were modified to improve occupant protection in side-impact crashes (note: information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on or near the driver door). The tested car was manufactured after the modifications had been made.
