The Insurance Institute for Highway Safety (IIHS) awarded the 2015 Acura TLX with the Top Safety Pick+ designation after receiving high marks in all safety tests.
The new midsize luxury sedan earned an acceptable rating in the difficult small overlap front test, good ratings in four other crashworthiness evaluations and a superior rating for front crash prevention.
While the TLX didn't perform as well in the overlap front test as the former Acura TL, which received a good rating, it did perform better than the TSX, which only received a marginal rating. The TLX replaced both the TL and TSX and includes a front-crash prevention system. The previous models did not.
The IIHS introduced the test in 2012 to measure the impact of a head on crash in which 25 percent of the vehicle's front end strikes a ridged barrier – like a tree or utility pole - at 40 mph. Measurements from the crash dummy indicates that while there is the possibility of injuries to the driver's left leg, the risk of other injuries of this severity are low.
In order to achieve the Institute's top rating, cars must earn good ratings in the moderate overlap front, side, roof strength and head restraint tests, an acceptable rating in the small overlap test and a front crash prevention rating of basic or higher.
