Buick 2013

Small overlap front: driver-side

Rating applies to 2013-14 models

Tested vehicle: 2013 Buick Encore 4-door 4wd

The Buick Encore was introduced in the 2013 model year. Two tests of the Encore were conducted because the onboard (car interior) cameras failed during the first test. As a result, the restraints and dummy kinematics rating is based primarily on the second test. Injury and structural ratings are based on both tests.

Driver restraints and dummy kinematics In the second test, the dummy’s head barely contacted the frontal airbag before sliding off the left side as the steering column moved 18 cm to the right, leaving the head vulnerable to contact with forward side structure and resulting in little airbag cushioning for the chest. (In the first test, the steering column moved 23 cm to the right.) Additionally, the seat belt allowed excessive forward excursion of the dummy’s head and torso. The side curtain airbag deployed too late during the second crash and does not have sufficient forward coverage to protect the head from contact with forward side structure and outside objects. The side torso airbag deployed in the first test but not in the second test. P

Action shot taken during the second of two small overlap frontal crash tests.

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 wasn’t maintained well (second test shown).

During the second crash, the dummy’s head barely contacted the frontal airbag before sliding off to the left as the steering column moved to the right. 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.

Door hinge pillar and instrument panel intrusion was extensive and contributed to a high risk of injuries to the left knee and left lower leg and a moderate risk to the left thigh (second test shown).

Action shot taken during the moderate overlap frontal 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 well.

Smeared greasepaint shows where the driver dummy’s head was protected from hitting hard structures during rebound by the side curtain airbag.

Intrusion into the driver’s space was minimal, and all leg and foot injury measures were low. The deployed knee airbag is resting on the dummy’s lower legs.
