Small overlap front: driver-side

Rating applies to 2019-24 models

Tested vehicle: 2019 Chevrolet Silverado 1500 LT Crew Cab 2wd

The Chevrolet Silverado 1500 and GMC Sierra 1500 Crew Cab were redesigned for the 2019 model year.

Driver restraints and dummy kinematics

Action shot taken during the driver-side small overlap frontal crash test.

The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was maintained reasonably well.

The frontal and side curtain airbags worked well together to keep the head from coming close to any stiff structure or outside objects that could cause injury.

Intrusion of the toepan contributed to a moderate risk of injuries to the left foot and right lower leg.

Action shot taken during the passenger-side small overlap frontal crash test.

The dummy's position in relation to the door frame and dashboard after the crash test indicates that the passenger's survival space was not maintained well.

The frontal and side curtain airbags worked well together to keep the passenger dummy’s head from coming close to any stiff structure or outside objects that could cause injury.

Extensive intrusion of the dashboard, toepan, and door hinge pillar contributed to a significant risk of injury to the right lower leg and a moderate risk to the left lower leg.

Tested vehicle: 2023 Chevrolet Silverado 1500 LT Crew Cab 4wd

The Chevrolet Silverado 1500 and GMC Sierra 1500 Crew Cab were redesigned for the 2019 model year. Two tests of the Silverado were conducted because the rear passenger data acquisition system failed during the first test. Driver dummy injuries, rear dummy restraints and kinematics and structural ratings are based on both tests. The rear dummy injury values are based only on the second test.
