A number of cars offer systems that can detect an impending collision and, in some cases, apply the brakes automatically. On Friday, a leading auto safety group issued its first ratings of the systems.

“Front crash prevention systems can add a thousand dollars or more to the cost of a new car. Our new ratings let consumers know which systems offer the most promise for the extra expense,” said David Zuby, IIHS chief research officer.
