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

The 1999 GMC Sonoma is a twin of the tested vehicle.

The Chevrolet S-10 and GMC Sonoma were redesigned for the 1994 model year. The Isuzu Hombre was introduced in 1996 and discontinued after the 2000 model year. For all three models, frontal airbags for both the driver and passenger became standard beginning with the 1998 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 both tibias and the right knee indicate that injuries to the knee and lower legs would be possible.

Restraints and dummy kinematics

Dummy movement wasn't well controlled. After the dummy moved forward into the airbag, it rebounded toward the driver door, which had bowed outward, and its head nearly hit the windowsill. In addition, there was too much movement of the steering wheel.
