Rating applies to 2018-19 models

Tested vehicle: 2018 Nissan Leaf SL 4-door

The Nissan Leaf was redesigned for the 2018 model year. 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. Ratings apply to both the Leaf (tested) and the structurally similar Leaf Plus, which was introduced in the 2019 model year.
