It was a surprise to me that public disclosure of crash test results is not required. The USA only requires that auto makers internally test to certify that a car meets minimum requirements.(NHTSA). The IIHS also tests cars and sometimes has info on cars NHTSA has not tested. As of 2020, no Porsche, Landrover or Jaguar has been NHTSA tested along with exotics and some very low volume vehicles (which the Air qualifies as). So it could be quite a while before we see independent test results or maybe never.
