The 2012 Mercedes-Benz C-Class, Audi A4 and two Lexus sedans — the IS 250/350 and the outgoing ES 350 — failed the latest round of IIHS frontal tests.
As we reported Monday, the Insurance Institute for Highway Safety’s new offset frontal-barrier test simulates a 40-mph collision with a rigid barrier that overlaps just 25% of the car. The test simulates a front-corner collision with a tree, a pole or another vehicle, a scenario that is responsible for almost 25% of front crashes that seriously injure or kill someone in front, IIHS says. The new test will augment the agency's existing frontal test, which crashes a car at 40 mph against a deformable barrier that overlaps 40% of the front.
"Outside of some automakers’ proving grounds, such a test isn’t currently conducted anywhere else in the United States or Europe," IIHS said in a statement, noting that despite an increasing number of cars that score well in frontal crash tests, some 10,000 highway deaths still come from frontal collisions each year.
