Crash tests continue to get ever tougher, and the new “small overlap” test from the Insurance Institute For Highway Safety is giving engineers fits. The new procedure, launched in August, subjects just 25 percent of a vehicle’s front end to an impact at 40 miles per hour, and it’s proven to be a lot tougher to ace than the institute’s old 40-percent overlap test, which is also still in use. The test is designed to simulate impact with a pole, tree or an offset other vehicle – all common crash scenarios.

In its initial round of tests, the IIHS found just three of 11 midsize luxury and near-premium cars up to the job of earning acceptable or good ratings. In this latest go around, the IIHS subjected 18 midsize family sedans to the test, with two earning good ratings, 11 earning acceptable scores, three netting marginal and two suffering poor marks. Of those tested, the Honda Accord and Suzuki Kizashi earned top marks.

Interestingly enough, the IIHS has gone out of its way to highlight the poor performances by the Toyota automobiles it tested. The Camry and Prius V were both called out for poor performances in the small overlap, deeming them “the worst performers of the midsize group.” This, despite the fact that both models were new for 2012. Interestingly, both vehicles previously earned Top Safety Pick status, showing just how tough the new small overlap test really is.

IIHS also called out the 2013 Volkswagen Jetta for a poor performance, noting that its driver airbag module actually detached from the steering column during the crash test. The IIHS notes that the detachment occurred “relatively late in the crash and didn’t affect the dummy’s movement,” but it still marked down the Volkswagen as a result.
