The 2008 GMC Sierra 1500 is a twin of the tested vehicle.
The Chevrolet Silverado 1500 and GMC Sierra 1500 were redesigned for the 2007 model year. Two tests of a 2009 Silverado 1500 were conducted, one with optional side airbags 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.
Driver — Measures taken from the dummy indicate that rib fractures and/or internal organ injuries would be likely in a crash of this severity. Serious neck injuries and a fracture of the pelvis would also be possible, and loading to the shoulder was excessive.
Passenger — Measures taken from the dummy indicate that rib fractures and/or internal organ injuries would be likely in a crash of this severity. The risk of significant injuries to other body regions is low.
Driver — The dummy's head was hit by the window sill of the driver door. This impact did not produce high head injury measures, but the head protection is inadequate.
Passenger — Although the intruding barrier did not hit the dummy's head in this test, the head was not protected from contacts outside the vehicle. This indicates that only slightly different crash circumstances could produce a direct hit to a person's head.
Tested vehicle specifications
|Tested vehicle||2009 Chevrolet Silverado LT 1500 (2wd crew cab) |
|Weight|| 5,176 lbs.|

How this test is conducted
Measures of occupant compartment intrusion on driver side
|B-pillar to longitudinal centerline of driver's seat (cm) |
Negative numbers indicate the amount by which the crush stopped short of the seat centerline.
