Last year 20 automakers that control 99 percent of the U.S. market agreed to make Automatic Emergency Braking (AEB) a standard feature across almost all models by 2022.

After one year, some are way ahead and others have barely started.

Consumer Reports has long called for automakers to make AEB standard equipment in cars sold in the U.S., and last year CR began awarding bonus points in the Overall Score of vehicles that include AEB and forward-collision warning (FCW) as standard features across all trim levels of a model.

“It shouldn’t take buying a luxury car or pricey add-ons for a consumer to get this protection,” says William Wallace, policy analyst for Consumers Union, the policy and mobilization arm of Consumer Reports. “All automakers should quickly make both low-speed and high-speed systems standard.”

The National Highway Traffic Safety Administration and the Insurance Institute for Highway Safety negotiated the voluntary agreement under the theory that consumers would benefit from the technology faster if compliance were voluntary, rather than mandated through a regulatory process. Consumer Reports supported the deal and agreed to monitor compliance. 

But the agreement only calls for implementing low-speed AEB systems. As a result, even if manufacturers meet the terms of the agreement, high-speed AEB may not be a standard feature on every model. Because motorists are more likely to be killed or seriously injured at higher speeds, Consumer Reports encourages automakers to offer high-speed AEB.

If a car equipped with AEB senses a potential collision with a vehicle in front and the driver doesn’t react in time, it brakes for you. The latest study from the IIHS found rear-end crashes for models equipped with AEB were cut by 50 percent.

The automakers promised that the technology would be made standard on all models except heavy-duty pickup trucks. The agreement also includes a pledge to adopt FCW.  

More on Advanced Safety Systems

So far, Volvo, Toyota, and Mercedes are leading the way. Volvo made AEB standard for all its models in 2014. Toyota aims to make AEB standard on all models by the end of 2017. Nissan is also ahead of schedule, saying it is likely to have standard AEB on more than a million vehicles sold in 2018. AEB comes standard on every Mercedes model except the G-Class. Mazda has taken a major step forward as well, with an announcement that low-speed AEB will come standard on all 2018 models except for the MX-5 Miata.

“Safety remains one of our top priorities, and we take a long-term view when it comes to our product decisions,” says Chris Nielsen, chief quality officer for Toyota. “Ultimately, as customer adoption rates for advanced safety features increase, we will be prepared to meet demand.”

Automakers that are sold on the technology, such as Nissan, describe it as a breakthrough that prevents not only fatal accidents but also the smaller fender-benders that can disrupt consumers’ lives. Nissan feels that even if it’s an unfamiliar technology, the company needs to “communicate to consumers, teach them the benefits of new technologies and create desire,” says Michael Bunce, Nissan North America’s vice president of product planning.

“In a market with so many choices, we want Nissan to stand out by standing for something,” Bunce says. “Our guiding principle is to innovate and bring unique, market-leading features to many of our vehicles, not just to the most expensive vehicles.”

And then there’s Ford and Fiat Chrysler. Neither offers standard AEB on any models.

Both still plan to meet the terms of the agreement, they say. “We strongly support the voluntary agreement to proliferate AEB,” says Eric Mayne, Fiat Chrysler spokesman. “Accordingly, we are adding our robust brand of the technology to a steadily growing number of vehicles.”

And Ford spokeswoman Elizabeth Weigandt says, “Ford was one of the original collaborators on the voluntary adoption of AEB standardization, and we have a plan to standardize over time.”

The Detroit area’s other automaker, GM, currently offers standard AEB on only one of 42 models sold under its four brands: Buick, Cadillac, Chevrolet, and GMC. It says AEB will be available on two-thirds of its models next year, but it won’t be a standard feature.

Although progress hasn’t been made across the board, David Zuby, executive vice president and chief research officer at the IIHS, says he is pleased with the steps that manufacturers have taken so far. “I think that’s good news for the idea that a voluntary commitment, while not having the same teeth as regulation, can achieve similar gains.”

NHTSA didn’t respond to questions for this article.

CR reached out to all 20 automakers involved with this agreement and asked them which of their models will have AEB as a standard or optional feature on their 2018 models. The chart below incorporates their responses.
