The 2003 GMC Sierra 1500 is a twin of the tested vehicle.
The Chevrolet Silverado 1500 and GMC Sierra 1500 were redesigned during the 1999 model year (the previous design extended into the early 1999 model year). The Classic nameplate was added in the 2007 model year to distinguish what effectively are carryover 2006 models from the redesigned 2007 Silverado 1500 and Sierra 1500.
Note: These ratings do NOT apply to the redesigned 2007 Chevrolet Silverado 1500 and GMC Sierra 1500.
Injury measures
Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity. Head acceleration from the belt housing hit was low.
Restraints and dummy kinematics
Dummy movement wasn't well controlled. After the dummy moved forward into the airbag, its head dropped down below the window sill. Then the head rebounded upward and hit the shoulder belt housing, which is mounted directly to the seat back. There was far too much upward movement of the steering wheel. Also, the driver seat came loose on one of its tracks and moved rearward slightly on the right side, where the safety belt buckle is anchored.
