Crash & Occupant safety – Passenger Vehicle Category

  • FMVSS, ECE, AIS, LATAM, ASEAN
  • USNCAP, IIHS,ANCAP,JNCAP, Euro NCAP*, KNCAP, China NCAP, Latin NCAP, GNCAP,ASEAN NCAP,BNCAP**

* It has most comprehensive list of evaluation for star rating calculation.

* Underdevelopment by ARAI INDIA), currently GNCAP can be followed (FODB with 64kmph & Side impact should pass in AIS 99)
