Small overlap front: driver-side

Rating applies to 2016-19 models built after October 2015

Tested vehicle: 2016 Hyundai Sonata Eco 4-door

The Hyundai Sonata was redesigned for the 2015 model year. Beginning with 2016 models, the driver's seat belt was modified, and front suspension changes were made to alter wheel movement during small overlap frontal crashes. Later, beginning with 2016 models built after October 2015, the structure was reinforced at the junction between the door sill and hinge pillar to improve occupant protection in small overlap crashes. (Information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on the driver door or adjacent B-pillar.)

The Kia Optima was redesigned for the 2016 model year and since then has been built on the same platform as the Hyundai Sonata. All 2016 and later Optimas include equivalent modifications made on the driver side of Sonatas built after October 2015.

Action shot taken during the driver-side small overlap frontal crash test of the 2016 Hyundai Sonata built after October 2015.

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.

Forces during the crash contributed to a moderate risk of injury to the dummy's left foot.

About the small overlap front test

Small overlap front: passenger-side

Rating applies to 2016-19 models

Tested vehicle: 2017 Hyundai Sonata SE 4-door

The Hyundai Sonata was redesigned for the 2015 model year. Beginning with 2016 models, the driver's seat belt was modified, and front suspension changes were made to alter left and right wheel movement during small overlap frontal crashes to improve occupant protection.

The Kia Optima was redesigned for the 2016 model year and since then has been built on the same platform as the Hyundai Sonata, with the exception that the Optima's passenger side structure was lacking some of the strengthening needed for optimal performance in passenger-side small overlap crashes.

Beginning with 2018 Optima models built after January 2018, the passenger-side door sill, lower door hinge pillar, and toepan were reinforced to improve occupant protection in such crashes. (Information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on the driver door or adjacent B-pillar.)

Passenger restraints and dummy kinematics
The dummy’s head contacted the frontal airbag but moved off toward the right side, leaving the head vulnerable to contact with forward structure. The side curtain airbag deployed and has sufficient forward coverage to protect the head from contact with side structure and outside objects. The side torso airbag also deployed.

Driver restraints and dummy kinematics

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 maintained well.

The dummy’s head contacted the frontal airbag but moved toward the right side, allowing the head to slip into the gap in coverage between the frontal and side curtain airbags.

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

About the small overlap front test

Moderate overlap front: original test

Rating applies to 2015-19 models

Tested vehicle: 2015 Hyundai Sonata Sport 2.0T 4-door

The Hyundai Sonata was redesigned for the 2015 model year and the Kia Optima was redesigned for the 2016 model year (since then the two cars have been built on the same platform). Moderate overlap frontal ratings are assigned by the Institute based on a test of a 2015 Sonata conducted by Hyundai.
