While product cycles can be as little as 36-months for a body-in-white to production,the convention has been a 48-month cycle.I suspect that the applicable NHTSA safety regulations for model years 48-months out,are already frozen,giving automakers ample time for engineering and verification.With finite element analysis,computers have been able to crash-test vehicles within a virtual domain since 1990.The actual crash testing is basically a confirmation of the numerical modelling.Bill Gates knows all about this.
