ARLINGTON, Va. --- The Insurance Institute for Highway Safety has given the 2007 Mini Cooper an overall rating of "good" for its performance in a frontal crash test. Based on crash tests, the institute rates vehicles as either "good," "acceptable," "marginal," or "poor." The Mini's impressive performance comes just four months after earning a five-star Euro NCAP rating for crash test performance in both front and side-impact tests. "Dummy movement was well controlled," the institute's report said in its assessment of restraints and dummy kinematics. "During rebound, the dummy's head hit the roof rail." In the assessment of injury measures, the institute acknowledged that a "high head acceleration occurred when the dummy's head hit the steering wheel through the airbag, indicating that head injuries would be possible." However, the institute added that "head acceleration from the roof rail hit was negligible." What's more, the institute said, "measures taken from the neck, chest, and both legs indicate low risk of injuries to these body regions in a crash of this severity." The testing was conducted by BMW as part of front crash test verification. The Mini Cooper's extra safety features include side airbags, electronic stability control (optional), antilock brakes and daytime running lights.
