For the first time in the history of automotive safety crash testing, an automobile nameplate has simultaneously earned top government and IIHS safety ratings for every vehicle in its line-up.

Recently, the National Highway Traffic Safety Administration (NHTSA), as part of New Car Assessment Program (NCAP) testing in the U.S., awarded the all-new 2009 Acura TL a five-star rating — its top rating — for side impact crash safety for both front and rear passenger seating positions.

In earlier NHTSA testing, the 2009 TL achieved top safety ratings (a five-star rating for frontal crash performance for both driver and front passenger along with a five-star rating for rollover resistance) meaning the 2009 TL now ranks as a top performer in all governmental safety ratings.

“Acura’s achievement means that no matter which Acura model buyers choose, they’re getting a high level protection for the most common types of real-world crashes,” said IIHS president Adrian Lund.
