General Motors earned half of the superior ratings from the Insurance Institute for Highway Safety’s rating program on front crash prevention. The Buick Regal, Cadillac CTS, Cadillac XTS and Chevrolet Impala are all considered industry leaders when purchased with GM’s available Front Automatic Braking system.
“We applaud GM’s commitment to making this important safety technology available not only on their luxury Cadillac products, but also on their more mainstream Chevrolet and Buick vehicles,” said IIHS Chief Research Officer David Zuby.

The IIHS previously recognized GM for front end safety, bestowing its highest safety rating – the 2014 Top Safety Pick + -- on the 2014 Chevrolet Equinox, GMC Terrain, and Chevrolet Malibu   with available forward collision alert. The Chevrolet Equinox and GMC Terrain are the only midsize SUVs out of the nine evaluated to earn “Good” ratings in the IIHS’s small overlap front crash test.
Front Automatic Braking can apply brakes when the system detects that a crash may be imminent and the driver has not taken action. It can apply hard braking to help reduce the severity of the crash, or it may assist the driver to avoid the crash.
Forward Collision Alert features crash-avoidance technologies that use a camera and sensors to help determine when the driver is getting too close to a vehicle ahead. This system alerts the driver with visual cues on the dashboard as well as audible signals. Drivers of the Cadillac XTS and CTS have the added benefit of the Safety Alert Seat which provides a vibrating pulse on both sides of the seat when a frontal threat is detected.
