In its "first real-world look at an advanced crash-avoidance technology," the Insurance Institute for Highway Safety's Highway Loss Data Institute (HLDI) has found that in low-speed traffic the Volvo XC60 and its City Safety forward collision-avoidance system (view Volvo video here) resulted in 27% fewer property damage liability coverage claims than other vehicles in its class (midsize luxury SUV). City Safety monitors vehicles up to 18 ft (5.5 m) in front with a laser sensor built into the windscreen at the height of the rearview mirror. Between 2 and 19 mph (3 and 31 km/h), the car automatically brakes if the driver does not respond in time when the car in front slows down or stops—or if the driver is driving too fast toward a stationary object. If the relative speed difference between the two vehicles is less than 9 mph (14 km/h), the collision can be entirely avoided. If the speed difference is between 9-19 mph, the speed at impact is reduced by about one-half, thereby mitigating the collision. City Safety also is standard on the 2011 and 2012 S60, 2012 S80, and 2012 XC70. HLDI says it is working with several automakers to evaluate various crash-avoidance technologies.
