Test details: The Chevrolet TrailBlazer was introduced in the 2002 model year, and the GMC Envoy was redesigned the same year. The Buick Rainier and Isuzu Ascender (5-passenger) were introduced in the 2004 model year. Beginning with 2005 models, structural, frontal airbag, and seat belt changes were made to improve occupant protection in frontal crashes. The Saab 9-7X was introduced late in the 2005 model year, and the Buick Rainier was discontinued after the 2007 model year. Restraints/dummy kinematics — Dummy movement was well controlled. During rebound, the dummy's head hit the B-pillar. 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 B-pillar hit was low. Left to right: * Action shot taken during the frontal offset crash test. Larger photo * 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. Larger photo * Smeared pink greasepaint indicates where the dummy's head hit the B-pillar. Head acceleration from this hit was low. Larger photo * Forces on the lower right leg were high enough to indicate the possibility of injuries. Larger photo Additional features: * Side airbags: front and rear head curtain airbags (standard in Saab 9-7X models, optional in all other models) * Rollover sensor: designed to deploy the side curtain airbags, if equipped, in the event of an impending rollover * Electronic stability control (beginning with 2005 Saab 9-7X models and all 2006 models) * Antilock brakes * Daytime running lights Tested vehicle specifications: * 2007 Chevrolet TrailBlazer LS 4wd * Class: Midsize SUV * Weight: 4,641 lbs. * Side airbags: front and rear head curtain airbags * Wheelbase: 113 in. * Length: 192 in. * Width: 75 in. * Engine: 4.2 L 6-cylinder * EPA ratings: 15 mpg city | 21 mpg highway
