Vibe must have been tested earlier. I found this link
http://www.nhtsa.dot.gov/NCAP/Cars/2003Cmpt.html It shows:2003 Vibe 4x2 - front driver & passenger 5 stars, rollover 4 stars2003 Vibe 4x4 - side front 5 stars & side rear 4 stars, rollover 4 starsI wonder whether the side ratings were with side air bags.
