On August 14, 2012, IIHS released the first results for a new test, called "small overlap front test." The new test, which is used in addition to the 40% offset test introduced in 1995, subjects only 25% of the front end of the vehicle to a 40 mph impact against a solid, rounded-off barrier. As a result, it is far more demanding on the vehicle structure than the 40% offset test. In the first round of test, composed of 11 midsized luxury and near-luxury vehicles, most vehicles did poorly; only three vehicles received "good" or "acceptable" ratings.
