electrical problems

[Hisham Amaral]

If this was anNCAP test it should have been performed at 35MPH. The last 18 years of my engineering work was in safety restraints and vehicle impact performance. The front end must have a very stiff structure to withstand the impact loads, however the dummies do not do so well the energy that did not get absorbed in the frame was transferred to the occupants. I don't understand the 5* rating that is printedat the bottomscreenbelow the video. Hisham Amaral W.

New Setra ($600K??) and 44 test dummies. Wonder how fast it was traveling when it hit the wall -- there was a lot of front end damage. Sure lets you know why they have alternate escape hatches!
