Two tests of the Genesis were conducted. In the first test, the dummy's head hit the steering wheel through the airbag, producing a high head acceleration. Also, forces on the dummy's right lower leg, knee, and foot indicated that injuries would be likely to the leg and possible to the knee and foot. In response, Hyundai modified the airbag and added padding behind the knee bolster in the area of the push-button ignition switch. In the second test, the right leg/foot injury rating improved to Good. Most injury data from the head were not obtained, but after the Institute reviewed comparable test data from Hyundai, the head/neck injury risk was rated Good in the second test.

The airbag and knee bolster modifications apply to all 2009 and later models manufactured after November 2008 (note: information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on or near the driver door). The cars manufactured before and after being modified are rated separately, except that the structural ratings for both vehicles are based on both Institute tests.

Injury Measures:
Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity. (Note: during the test, most injury data from the head were not obtained, but after the Institute reviewed comparable head and neck test data from Hyundai, the head/neck injury risk was rated good.)

Restraints / Dummy Kinematics:
Dummy movement was well controlled. During rebound, the dummy's head hit the roof rail.

The Hyundai Genesis was introduced in the 2009 model year. Beginning with 2010 models built after January 2010, design changes were made to the roof structure and B-pillar to improve occupant protection in rollover and side impact crashes (note: information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on or near the driver door).

Two tests of the modified 2010 Genesis were conducted, one by the Institute and the other by Hyundai as part of side crash test verification. Ratings are based on both tests.

Driver Injury Measures:
Measures from the dummies in the two tests, taken together, indicate that rib fractures would be possible in a crash of this severity. The risk of significant injuries to other body regions is low.

Passenger Injury Measures:
In both tests, measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.
