None of 6 minivans, all 2008 models, is designed to resist vehicle damage in many low-speed collisions. The front and rear bumper systems on these minivans allowed $5,000 or more damage in a series of 4 crash tests conducted at 3 and 6 mph. The Nissan Quest was the worst, sustaining damage that cost more than $8,000 to repair. These are the results of recent crash tests conducted by the Insurance Institute for Highway Safety to assess and compare how well vehicle bumper systems resist damage in the kinds of low-speed collisions that frequently occur in commuter traffic and parking lots. In the Institute's bumper tests, each vehicle is run into a barrier designed to mimic the design of a car bumper. The steel barrier's plastic absorber and flexible cover simulate cars' energy absorbers and plastic bumper covers. The series of 4 tests includes front and rear full-width impacts at 6 mph and front and rear corner impacts at 3 mph.
