Update 2023: The MAZDA MX-30 PHEV is a variant of the MX-30. Some additional tests and checks have been done to ensure that the rating of the MX-30, tested in 2020, applies to the Plug-in Hybrid variant.

Euro NCAP performs a series of crash and safety tests on car models:
a frontal impact test, 50% of the width of the car is striking an oncoming deformable barrier, also travelling at 50 km/h
a frontal impact test, the car impacts a rigid full width barrier
a side impact test, a mobile deformable barrier impacts the driver's door
a pole test, the tested car is propelled sideways into a rigid pole and the robustness of the centre airbag is evaluated.
A series of pedestrian tests are conducted with different impactors, adult and child head form, lower and upper leg form and whiplash tests are performed on a sled as well as AEB pedestrian and cyclist tests.
Active safety is tested based on the car’s equipment: autonomous emergency braking car-to-car scenarios, occupant status monitoring (including seatbelt reminders), lane support and speed assistance technologies.
