IIHS announces low-speed bumper tests of mid-size sedans; 4 of 6 midsize sedans improve; none earns good rating

Bumpers on 4 of 6 midsize sedans improve;
none earns good rating in low-speed tests

ARLINGTON, VA — Bumpers on 2009 models of the Honda Accord, Hyundai Sonata, Mazda 6, and Nissan Maxima performed better than their 2007 predecessors in low-speed crash tests conducted by the Insurance Institute for Highway Safety. Bumpers on the 2009 Chevrolet Malibu and 2010 Ford Fusion did worse than earlier models. None of the 6 popular midsize sedans earns the top rating of good in a recent series of tests designed to assess and compare how well bumpers resist damage in everyday fender-benders. The Mazda 6 improves to acceptable from marginal, with an average repair cost of less than $900 after 4 tests at 3 and 6 mph. The Accord and Sonata improve to marginal from poor. The Fusion slips to poor from marginal, and the Maxima and Malibu remain poor.

"Consumers buy midsize cars for practical reasons. There's nothing practical about a $1,000-plus repair bill after a minor bump in commuter traffic," says Joe Nolan, Institute senior vice president.

This is the second group of vehicles the Institute has evaluated under a new bumper ratings protocol based on repair costs averaged and weighted to reflect real-world damage patterns and insurance claims frequency (see table below). The Institute rates bumpers good, acceptable, marginal, or poor based on performance in 4 tests — front and rear full-width impacts at 6 mph and front and rear corner impacts at 3 mph. Each vehicle is run into a steel barrier designed to mimic the design of a car bumper, with the barrier's plastic absorber and flexible cover simulating typical cars' energy absorbers and plastic bumper covers. These tests are designed to drive bumper improvements that lead to better damage resistance in a range of real-world crashes.
