The tests are done at 64kmph. But in reality when two car moves and crashes head on at say 60kmph the impact is supposed to be twice than what it was tested. |

Bit confused here - did you mean two cars crashing head on at say 30kmph each is equivalent to one of them crashing onto an immovable object at 30kmph? |

Thanks for clarification. In continuation of this, let us assume that car A is at 30kmph and other car B is at 80kmph. Will this still be applicable? |

No, the cars need to be identical in weight and speed. That determines their kinetic energy. In your example the faster case has a considerable higher kinetic energy, especially as in the kinetic formula speed is squared. So once they hit the faster car will actually push the slower car back, so from 30 kmph going one way to going reverse. Huge forces involved! Safety in cars is down to two main elements: Making sure the occupants don’t get crushed and making sure the occupants have as little deceleration as possible. It is all about how to absorb that energy in a very short space of time and space. Jeroen |
A key change is the implementation of a new moving barrier to moving car frontal crash test, replacing the regulation-based moderate offset-deformable barrier test, used by Euro NCAP for the last 23 years. This new crash test not only evaluates the protection of occupants inside the car, but also assesses how the cars’ front-end structurers contribute to injuries in the collision partner. Important innovations are the Mobile Progressive Deformable Barrier and the unique method to rate vehicle compatibility, as well as the first adoption of the world’s most advanced “THOR” mid-sized male crash test dummy. Side impacts account for the second highest frequency of death or serious injuries. The latest updates to this area of the safety assessment include adjustments to the near-side barrier test speed and mass, increasing the severity of the test. More significantly, Euro NCAP will for the first time evaluate far-side impact protection, focussing on driver protection and the potential interaction between driver and front seat passenger. With the latter test, the protection offered by new-to-market countermeasures such as centre airbags can be adequately verified. |
Yaris emerges with flying colours from Euro NCAP’s 2020 test programme. The car is the first to be subjected to an all-new frontal offset test, which replaces the one previously used since the programme started in 1997, and is the first to feature a counter-measure for injuries in far-side impacts. The mobile progressive deformable barrier (MPDB) test assesses the protection a car offers its occupants as well as the risks it poses to the car it has crashed into. The Yaris, in general, does well, its small size and benign front end making it one of the less aggressive crash partners on the road. Two centre-mounted airbags inflate in side impacts to limit an occupants’ travel to the opposite side of the vehicle and to mitigate the risk of occupant to occupant contact. The Yaris also showcases the rapid advancements in crash avoidance technology: the latest generation of Toyota Safety Sense now can stop the vehicle during turning to avoid a crash |
