In tests designed to replicate low-speed impacts, the bumpers of several luxury cars failed to prevent costly damage. In one case, a Mercedes-Benz C-class sedan sustained almost $5,500 in damage when hit in its front bumper at a speed of just 6 miles per hour.

The cars struck a barrier, designed to mimic the bumper of another car, straight-on from the front and from the rear at six miles per hour and diagonally into front and rear corners at three miles per hour. The Institute, a private organization funded by insurance companies, estimated repair costs after each test.

The C-class performed poorly in large part because its front bumper slid down below the impact barrier during the test.


The vehicle sustaining the most total damage was the Infiniti G35, made by Nissan, which had total estimated repair costs of $14,000. In the straight-on front impact test alone, the G35 sustained $5,223 in damage.


The Institute wasn't enthusiastic about even the Saab's performance in these tests, however.
