The Insurance institute of safety gives the new 2008 Ford Taurus X a superior safety rating in a rear end collision due to its adjustable headrests. They did not even rate the Enclave because it has non adjustable headreasts which implies the Enclave is not safe in rear collisions. The Tauraus X gets excellent safety ratings in all other safety catagories as does the Enclave. Whiplash injuries could be extremely severe and frequent in the Enclave. Does this concern anyone? The Enclave has a back up camera and adaptive HID headlights. Taurus X does not, but the headrests concern me to the point I am considering a Taurus X now.
