Insurance Institute Unveils New Crash Test
The idea is to improve protection for people in frontal crashes
Thursday, August 16, 2012
Only three of 11 midsize luxury and near-luxury cars evaluated earn good or acceptable ratings in the Insurance Institute for Highway Safety’s (IIHS) new small overlap frontal crash test -- the latest addition to a suite of tests designed to help consumers pick the safest vehicles.
The Acura TL and Volvo S60 earn good ratings, while the Infiniti G earns acceptable. The Acura TSX, BMW 3 series, Lincoln MKZ and Volkswagen CC earn marginal ratings. The Mercedes-Benz C-Class, Lexus IS 250/350, Audi A4 and Lexus ES 350 earn poor. All of these cars are 2012 models.
In the test, 25 percent of a car’s front end on the driver side strikes a 5-foot-tall rigid barrier at 40 mph. A 50th
percentile male Hybrid III dummy is belted in the driver seat. The test is designed to replicate what happens when the front corner of a car collides with another vehicle or an object like a tree or utility pole. Outside of some automakers’ proving grounds, such a test isn’t currently conducted anywhere else in the United States or Europe.
“Nearly every new car performs well in other frontal crash tests conducted by the Institute and the federal government, but we still see more than 10,000 deaths in frontal crashes each year,” Institute President Adrian Lund says. “Small overlap crashes are a major source of these fatalities. This new test program is based on years of analyzing real-world frontal crashes and then replicating them in our crash test facility to determine how people are being seriously injured and how cars can be designed to protect them better. We think this is the next step in improving frontal crash protection.”
The number of drivers of 0-3-year-old passenger vehicles involved in fatal frontal crashes has fallen 55 percent since 2001. Much of the improved outlook is due to the success of consumer information testing like the New Car Assessment Program begun by the National Highway Traffic Safety Administration (NHTSA) in 1978 and crashworthiness evaluations the Institute started in 1995. In NHTSA’s frontal test, passenger vehicles crash at 35 mph into a rigid barrier covering the full width of the vehicle. In the Institute’s 40 mph offset frontal test, now called a moderate overlap frontal test, 40 percent of the total width of a vehicle strikes a deformable barrier on the driver side.
In a 2009 Institute study of vehicles with good ratings for frontal crash protection, small overlap crashes accounted for nearly a quarter of the frontal crashes involving serious or fatal injury to front seat occupants. Another 24 percent of the frontal crashes were moderate overlap crashes, although they likely occurred at much higher speeds than the Institute’s moderate overlap test. An additional 14 percent occurred when passenger vehicles underrode large trucks, SUVs or other high-riding passenger vehicles. The Institute is exploring countermeasures for large truck underride crashes and in other research has found that the problem of crash incompatibility between cars and SUVs is being reduced.
