You may remember how the Tesla Motors Inc (NASDAQ:TSLA) Model S received the top U.S. crash rating by the National Highway Traffic Safety Administration (NHTSA). Rhett Allain, an associate professor of physics at Southeastern Louisiana University, was determined to find out how the Model S was so safe.
There is a lot of math involved in Allain’s article, but the conclusion is that the car’s ability to crumple easier makes the vehicle safer without smashing “up the human.”
Allain wrote “the Tesla Model S does have an advantage ? it?s new. Most cars have some type of legacy structure that they are built on. If you want to use a 2008 engine in your traditional car, you have to have a 2008-like frame in which to put this engine. The Model S is a pure electric car. It doesn?t have these legacy issues.”
Most other cars have some type of legacy structure that they are built on. Since the Model S is a pure electric car, it does not have legacy issues.
Below is a demo video of the Tesla Model S frontal crash test. You will notice how much of the car crumples and absorbs the impact before the dummy hits the air bag:
