Moderate overlap front

Rating applies to 2005-10 models

Tested vehicle: 2009 Chevrolet Cobalt LS 2-door

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. The Pontiac G5 was discontinued after the 2009 model year and the Cobalt after the 2010 model year.

Restraints and dummy kinematics

Action shot taken during the frontal crash test.

The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained reasonably well.

Smeared greasepaint indicates where the dummy's head hit the roof rail and head restraint during rebound. Head accelerations from these hits were negligible.

Forces on the lower right leg were high enough to indicate the possibility of injuries.

How the moderate overlap front test is conducted

Side

Rating applies to 2009-10 models built after May 2009

Tested vehicle: 2009 Chevrolet Cobalt LT 2-door with standard front and rear head curtain airbags

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.

View of the vehicle after the crash with door removed, showing the side airbag and damage to the occupant compartment.

Smeared greasepaint shows where the driver dummy's head was protected from being hit by hard structures by the side curtain airbag.

Smeared greasepaint shows where the rear passenger dummy’s head was protected by the side airbag.
