|Side crash test ratings can be compared across vehicle categories.
The 2011 GMC Canyon crew cab is a twin of the tested vehicle.
The Chevrolet Colorado and GMC Canyon were introduced in the 2004 model year as replacements for the Chevrolet S-10 and GMC Sonoma. Side airbags became standard beginning with 2010 models (they had been optional in 2004-09 models). Structure ratings are based on this test and on an earlier test of a 2008 Colorado model without side airbags.
These side impact crash test ratings also apply to the Isuzu i-series pickup, which was introduced in the 2006 model year, because crew cab models had standard side airbags. The i-series was discontinued after the 2008 model year.
Driver — Measures taken from the dummy indicate that rib fractures and/or internal organ injuries plus a fracture of the pelvis would be likely in a crash of this severity. In addition, loading to the shoulder was excessive.
Passenger — Measures taken from the dummy indicate that rib fractures would be possible in a crash of this severity. The risk of significant injuries to other body regions is low.
Driver — The side curtain airbag adequately covered the window opening near the dummy's head during deployment, but the head then moved outward and downward into near proximity with the intruding barrier. Although the barrier did not hit the dummy's head in this test, this near miss indicates that only slightly different crash circumstances could produce a direct hit to a person's head.
Passenger — The side curtain airbag did not deploy properly, and the dummy's head was hit by the window frame of the rear passenger door and the pillar behind the door. This impact did not produce high head injury measures, but the head protection is inadequate.

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.
