Manufacturers make progress on voluntary commitment to include automatic emergency braking on all new vehicles

Washington, DC — Four of 20 automakers report that automatic emergency braking (AEB) is standard on more than half of their 2017 model year vehicles, the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS) announced in the first update of manufacturer progress toward equipping every new vehicle with the crash avoidance technology. Even without making it standard, another five automakers report that more than 30 percent of vehicles they produced in 2017 were equipped with AEB.

"The growing number of vehicles offering automated emergency braking is good news for America's motorists and passengers," says U.S. Transportation Secretary Elaine L. Chao. "With each model year, manufacturers will increasingly utilize technology to allow vehicles to 'see' the world around them and navigate it more safely."

Twenty automakers pledged to voluntarily equip virtually all new passenger vehicles by Sept. 1, 2022, with a low-speed AEB system that includes forward collision warning (FCW), technology proven to help prevent and mitigate front-to-rear crashes. The commitment is intended to get the technology into a wider swath of the vehicle fleet faster than otherwise possible today.

"IIHS is pleased to see that automakers are steadily moving toward the shared goal of putting standard AEB into every new car they sell," says David Zuby, executive vice president and chief research officer of IIHS. "This is a big win for safety on our nation's roads, which will see fewer crashes and injuries because of this commitment."

By 2025, the commitment will prevent 28,000 crashes and 12,000 injuries, IIHS estimates. Consumer Reports supported the commitment and agreed to assist in monitoring automaker progress.

"This progress is great news for luxury car buyers and many others, but many automakers still need to do more, as Consumer Reports analysis indicates that only 19 percent of 2017 models included these lifesaving technologies as standard features," says David Friedman, director, cars and product policy and analysis at Consumers Union, the policy and mobilization division of Consumer Reports. "Automakers, safety groups and the government should also work together to make highway operation and pedestrian detection standard features on all AEB systems."

Manufacturers recently submitted their first yearly progress report to NHTSA on the AEB status of the 2017 fleet for vehicles manufactured from Sept. 1, 2016, through Aug. 31, 2017, for the U.S. market (Docket ID: NHTSA-2015-0101). The participating automakers include Audi, BMW, Fiat Chrysler, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Kia, Maserati, Mazda, Mercedes-Benz, Mitsubishi Motors, Nissan, Porsche, Subaru, Tesla Motors, Toyota, Volkswagen and Volvo. These companies represent more than 99 percent of the U.S. automobile market.

Toyota is the frontrunner when it comes to having the largest number of 2017 vehicles with standard AEB. The automaker equipped 56 percent of its 2017 fleet — 1.4 of 2.5 million vehicles — with AEB. General Motors has the second-highest number of 2017 models with AEB — 551,777 of 2.8 million vehicles, representing 20 percent of its 2017 fleet. Honda is third-highest with 492,330 of 1.6 million vehicles with AEB, representing 30 percent of its 2017 fleet.

In terms of the proportion of vehicles produced with AEB, luxury makers in general lead the way. Tesla included the technology on nearly all 2017 Model S cars and Model X SUVs, either as original equipment or via an over-the-air software update, although the feature was deactivated on some vehicles for part of 2017. Mercedes-Benz equipped 96 percent of its 2017 vehicles with standard AEB. Seventy-three percent of 2017 Audi vehicles have AEB, followed by 68 percent of Volvos and 58 percent of BMWs. Just under half of Subaru's 2017 vehicles have AEB.

Other manufacturers have yet to make significant progress. Fewer than 10 percent of 2017 vehicles sold by Fiat Chrysler, Ford, Hyundai, Kia and Mitsubishi have AEB. Jaguar Land Rover and Porsche didn't report any 2017 vehicles with AEB conforming to the commitment's requirements.

Background

Initially announced with 10 automakers in September 2015, and another 10 in March 2016, the voluntary commitment was brokered by NHTSA and IIHS to make AEB with FCW standard on virtually all light-duty cars and trucks with a gross vehicle weight of 8,500 pounds or less beginning no later than Sept. 1, 2022. The commitment calls for the technology to be standard on virtually all trucks with a gross vehicle weight between 8,501 pounds and 10,000 pounds beginning no later than Sept. 1, 2025.

AEB, also known as autobrake, among other names, includes a range of systems designed to address the large number of rear-end crashes in which drivers do not apply the brakes or fail to apply sufficient braking power to avoid or mitigate a crash. AEB systems use on-vehicle sensors such as radar, cameras or lasers to detect an imminent crash, warn the driver and, if the driver does not take sufficient action, engage the brakes. Forward collision warning alerts drivers to conflicts ahead but doesn't take action for the driver. AEB systems halve rear-end crashes, while FCW alone reduces them by nearly a third, IIHS research indicates.

Conforming systems must come with FCW that meets 2 of 3 NHTSA 5-Star Safety Ratings' requirements and AEB that earns at least an "advanced" rating from IIHS. Although a low-speed AEB system is standard on all Volvo passenger vehicles, not all include forward collision warning as outlined in the voluntary commitment. Mazda also offers a low-speed AEB system without forward collision warning.
