According to The New York Times "Wheels" blog:

"The revamped system provides an overall ratings score to help make comparing vehicle safety easier. The score will combine findings from the frontal crash test and side crash test, as well as a new side-impact oblique pole and rollover test."

The full set of new scores -- 33 in total -- after the jump, but as a quick aside, only two of those received the highest vehicle score of five stars: the rear-wheel-drive BMW 5-Series sedan and the Hyundai Sonata (applicable to all those built after July 2 of this year.)
