The 2013 Acura TL doesn't have a perfect set of safety ratings, but this year it's looking better.
Last year--or at least, the earlier part of last year--the crash-test ratings from the Insurance Institute for Highway Safety (IIHS) and the federal government (NCAP) weren't in accordance. Those from the federal government were quite poor, in fact; but late in the 2012 model year the TL was retested and it now earns better ratings of four stars overall, and four stars both for frontal and side impact.
In tests from the IIHS, on the other hand, the TL has achieved top 'good' results across the board, and it's been a Top Safety Pick.
All TL models include six airbags (front side airbags and full-length side-curtain bags), four-wheel disc brakes with ABF, Brake Assist, and electronic stability control. Rear headrests can flip neatly out of the way when nobody's back there, which helps visibility, and a rearview camera system is available. The Advance model also includes a Blind Spot Information System.
