NHTSA Crash Test Ratings
NHTSA gave the 2005 TT no overall, frontal or side rating. It did rate each seat in those tests and lists the seat ratings under Rating Breakdown on its page. We show them the same way below. These tests are from before 2011, so the stars are not comparable with ratings for 2011 and newer models. See the 2005 TT ratings on NHTSA.gov.
