Small overlap front: driver-side

Rating applies to 2013-17 models

Tested vehicle: 2014 Nissan Leaf S 4-door

The Nissan Leaf was introduced in the 2011 model year and re-engineered beginning with 2013 models. The car is a plug-in battery-electric vehicle with no gasoline or diesel engine to help power the car.

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 23 cm to the right, leaving the head vulnerable to contact with forward side structure and allowing little airbag cushioning for the chest. The side curtain airbag deployed but does not have sufficient forward coverage to protect the head from contact with forward side structure and outside objects. The side torso airbag 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 not maintained well.

During the crash, the dummy's head and torso barely contacted the airbag before sliding off to the left as the steering column moved to the right. The side curtain airbag did not extend far enough forward toward the A-pillar.

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 significant risk to the left thigh.

How the driver-side small overlap front test is conducted

Moderate overlap front: original test

Rating applies to 2013-17 models

Tested vehicle: 2013 Nissan Leaf SL 4-door

The Nissan Leaf was introduced in the 2011 model year and re-engineered beginning with 2013 models. The car is a plug-in battery-electric vehicle with no gasoline or diesel engine to help power the car. Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by Nissan as part of frontal crash test verification.

Rating applies to 2013-17 models

Tested vehicle: 2013 Nissan Leaf SV 4-door with standard front and rear head curtain airbags and standard front seat-mounted torso airbags

The Nissan Leaf was introduced in the 2011 model year and re-engineered beginning with 2013 models. The car is a plug-in battery-electric vehicle with no gasoline or diesel engine to help power the car. Side ratings are assigned by the Institute based on a test conducted by Nissan as part of side crash test verification.
