More cars are coming equipped with robotic functions that protect drivers from front-end crashes with other vehicles or objects, which could result in fewer crashes and lower insurance rates for drivers.
The Insurance Institute for Highway Safety said 52% of the 784 new vehicle models come with technology that alerts a driver to a pending crash as either a standard or optional feature.
Among 2015 models, 27% also offer robotic braking, which automatically slows or stops the vehicle without driver intervention if a crash is imminent. That's more than twice as many as in the 2012 model year.
"Automatic braking is an accessible technology that's within reach for many drivers," said David Zuby, the institute's executive vice president and chief research officer. "That's a welcome sign for highway safety and helps pave the way for the eventual deployment of fully autonomous vehicles."
Early studies are finding the technology is effective. Front-crash prevention systems use cameras, radar and laser sensors to judge whether a vehicle is getting too close to one in front of it. Most systems issue a warning and precharge the brakes to maximize their effect if the driver responds by braking, while others have robotic braking.
Automatic braking systems slash front-end crashes by 14% over the same vehicles that don't offer the feature, according to the institute's research. Vehicles that only alert drivers to a potential crash, but don't stop the car, cut collisions by 7%.
While the trade group has not measured the technology's effect on insurance premiums, it believes fewer crashes will soon be reflected in lower rates, said Russ Rader, an institute spokesman.
"Progressive is starting to lower rates for vehicles with stability control, adaptive headlights and forward-collision warning with braking," said Mike Doerfler, the insurer's product development manager. "We're introducing that on a state-by-state basis."
But vehicle design will influence which vehicles eventually realize premium savings, Rader said.
Many automakers are putting the crash-prevention sensors behind the grille in the front end where they're vulnerable to being damaged.
"The sensors are expensive to replace, so that can offset the cost benefits of fewer crashes," he said.
Some manufacturers are making adjustments and moving the sensors to the windshield ahead of the rear-view mirror, where they're better protected, Rader said.
The insurance group tested the systems and rated the vehicles as basic, advanced or superior for front-crash prevention depending on whether they offer autobrake and, if so, how effective it is in tests at 12 and 25 mph.
Typically, these systems are offered on luxury vehicles or as expensive options. But some automakers, including
Toyota, for example, plans to offer safety-package options for nearly every Toyota and
Mercedes-Benz is the first automaker to offer a standard front-crash prevention system that earns the "superior" rating in IIHS test track evaluations. The system comes on Mercedes' 2015 C-Class, CLA and E-Class.
The technology is catching on with more mainstream nameplates. Seven of the 19 superior- or advanced-rated models in the institute’s latest testing round are moderately priced:
In the latest testing, 14 new models earned the superior rating and five won the advanced rating.
The “superior” vehicles included the 2016
BMW's X3 earned an advanced rating when equipped with BMW's camera-only system, called City Braking Function, and is rated superior when equipped with a camera- and radar-based system.
Acura was pleased with the results.
"Acura is committed to implementing the AcuraWatch suite of safety and driver-assistive technologies on all models, and the recent IIHS results further validates our effort to remain the safety leader in the luxury segment," said Gary Robinson, manager of Acura product planning.
