Small overlap front: driver-side
Rating applies to 2012-15 models built before March 2015
Tested vehicle: 2013 Chevrolet Sonic LT 4-door
The Chevrolet Sonic was introduced in the 2012 model year. The small overlap frontal ratings apply to both the 4-door sedan and hatchback (5-door) versions of the Sonic.

| Driver restraints and dummy kinematics The dummy’s head barely contacted the frontal airbag before sliding off the left side as the steering column moved to the right, leaving the head vulnerable to contact with forward side structure. Additionally, the seat belt allowed excessive forward excursion of the dummy’s head and torso. The side curtain airbag deployed too late during the crash, after the head had moved to the left and was already rebounding, outboard of the inflating curtain, leaving the dummy's head vulnerable to contact with side structure and outside objects. |
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.
During the crash, the dummy's head barely contacted the frontal airbag before sliding off to the left, and the side curtain airbag deployed too late (after the time shown in the freeze frame) to offer any head protection, leaving the dummy's head exposed to contact with side structure and outside objects. The seat belt allowed the dummy to move too far forward, as is evident from the gap between the seat back and the dummy's torso.
Even though the knee airbag deployed, intrusion of the instrument panel contributed to a significant risk of injury to the right lower leg and a moderate risk to the left knee.

Action shot taken during the frontal offset crash test.
The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained very well.
A high head acceleration occurred when the dummy's head hit the steering wheel through the airbag.
Smeared greasepaint shows where the driver dummy's head was protected from hitting hard structures during rebound by the side curtain airbag.
