This crash test has been done by the ADAC.
The first one: a frontal crash at 64kph. The second one, an impact in the back by a "car ram" of 1400kg launched at 80kph.
As you can imagine, the car looks like a thimble after… But, no electric problem, just a minor break of the battery pack protective case under the violence of the second impact…
In case of crash the i-MiEV
uses a safety device which allows to immediately stop any electricity flow protecting passengers and rescuers.
