Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

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.

Injury measures

Measures taken from the head, neck, and chest indicate low risk of injuries to these body regions in a crash of this severity. Forces on the right tibia indicate that injuries to the lower leg would be possible. Head acceleration from the roof rail hit was negligible.

Restraints and dummy kinematics

Dummy movement was well controlled. During rebound, the dummy's head hit the roof rail after first contacting the head restraint.
