Default Nissan Leaf awarded 5-star rating in the toughest Euro NCAP test to date

New LEAF charging ahead with 5 star result in toughest safety tests to date.

The LEAF is the first car to be assessed against Euro NCAPís improved and extended protocols for 2018.

As road casualty numbers plateau, more action is needed to ensure that new vehicles offer the latest and best safety technology.


Cyclist-detection with auto brake technology is tested for the first time on the LEAF and is included with AEB Pedestrian in a new designation called AEB Vulnerable Road Users (AEB VRU). Detecting cyclists presents new challenges to car manufacturers, both from a hardware and a software perspective: sensors must have a wide angle of view to detect fast-moving cyclists in good time, and complex algorithms are needed to ensure correct identification of potential collision threats while avoiding false activations.

Other rating updates for 2018 include testing of pedestrian detection in darkness and obscure lighting conditions to ensure these systems work at all times. Emergency Lane Keeping (ELK) systems are the newest generation of intelligent lane support systems that autonomously take evasive action if the car is in danger of leaving the road or of colliding with another vehicle.

New Euro NCAP tests verify that the system reacts to a road edge, marked and unmarked, to ensure the car does not run off-road; that the car returns safely to its lane when an overtaking manoeuvre is attempted and an oncoming vehicle is detected; and that the car is prevented from inadvertently steering into the path of a vehicle which is overtaking in an adjacent lane.

Default Nissan Leaf scores 5 stars in updated Euro NCAP crash tests

The Nissan Leaf become the first car to be tested under the updated Euro NCAP norms. The electric hatchback managed to score a 5-star rating in the crash tests.

Euro NCAP has updated its testing methodology for 2018. It includes new sections like cyclist detection, lane-keeping assist and pedestrian detection in the dark as well as revised tests for autonomous emergency braking (AEB). New sections for safety assist systems in a car now include ESC, seatbelt reminders for all occupants, speed assistance, lane assist and high-speed AEB tests.

The cyclist detection was thanks to a grant of the Dutch government to develop a protocol for the detection of cyclists. Euro NCAP makes use of a cycle mounted on a moving platform with an articulating dummy that can mimic the pedalling action. Tests include a cyclist coming perpendicular to the car as well as one going in the same direction of the car. In case of pedestrian safety, tests are designed to factor in pedestrians jumping out of parked cars, kids and those walking parallel to the car. It uses a revised dummy and tests are repeated in low-light conditions.

Changes in the AEB include an updated target car, which is stationary, slow moving or stops suddenly to gauge the system’s response. Speeds up to 80 km/h are used. There is an additional emphasis on safety assist systems including lane departure warning, blind spot warnings and speed assistance including adaptive cruise control and autonomous braking systems.
