Small overlap front: driver-side

Rating applies to 2015-19 models

Tested vehicle: 2017 Chevrolet Impala 1LT 4-door

The Chevrolet Impala was redesigned for the 2014 model year. Beginning with the 2015 model year, the front-end structure was modified and the door sill was reinforced to improve occupant protection in small overlap frontal crashes.

Driver restraints and dummy kinematics
The dummy’s head contacted the frontal airbag but then slid off the left side, leaving the head vulnerable to contact with forward structure. The side curtain airbag deployed and had sufficient forward coverage to protect the head from contact with side structure and outside objects. The side torso airbag also deployed.

Action shot taken during the 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 dummy's head contacted the frontal airbag but slid completely off the left side, allowing the head to move into the gap in coverage between the frontal and side curtain airbags.

The driver's space was maintained reasonably well, and risk of injuries to the dummy's legs and feet was low.
