Neither the Insurance Institute for Highway Safety (IIHS) nor the National Highway Traffic Safety Administration (NHTSA) has tested the 2009 BMW 6-Series.
According to reviewers, the 6-Series ranks high for its safety systems, but even with all of these excellent safety precautions in the BMW 6-Series, ConsumerGuide mentions, "Aft visibility is tricky in coupes" and restricted in "top-up convertibles."
Convertible versions of the 2009 BMW 6-Series come standard with "a rollover protection system," says Edmunds, and optional features include a "night vision system that uses a thermal imaging camera to spot potential obstacles" and "a new lane departure warning system."
MyRide.com points out that the 6-Series is equipped with "two-stage front airbags, side-impact airbags for front seat passengers, active knee protection airbags, and dual threshold deployment of the seatbelt pretensioners." And Road & Track adds to that list, explaining, "Brake Assistant which, working in conjunction with the car's optional radar-based active cruise control and the stability control systems, will pre-load the brakes should the system decide that the driver is possibly getting into a position where he/she might need additional stopping power." Both systems work together to load the brakes of the BMW 6-Series in case the driver needs additional stopping power.
