Having its nose higher than most bumpers is going to deflect the thing up into the air in an accident. This is never a good thing in a crash. Especially in a car that is prone to being rolled over (not to mention one with gull wing doors). A hit from the rear to one side has a far greater likely hood of rolling it due to the way the rear end slopes up from the sides.
The choice of lithium Ion batteries poses a serious fire risk (if you have ever seen one of these batteries go you know what I'm talking about). The energy density of a battery system big enough for a car is scary. |
O.K. first point. You need to watch a few vids on the Aptera. The shell is designed to be so strong an elephant could stand on it.
Second, I believe the reverse trike design makes it more stable than older tadpole designs, and I believe this design is much more likely to spin out than even a regular car. Just watch a few videos on the T Rex.
Third and most important. The Lithium battery that needs coolant are the lithium ions referred to as lithium cobalt oxide. Those are the thermal runaway batteries you are talking about. Anybody looking to use lithiums should look at Lithium Iron Phosphate. It is a much cooler running, much more stable and longer cycle battery chemistry than the others you are talking about. All of the home converted electric cars I know of using lithiums are using LiFePo batteries. You can find a dozen or more websites selling them now. They are the large format rectangular, yellow, blue or white batteries you may have seen pictures of.
