What happened
The Insurance Institute for Highway Safety (IIHS) is an independent nonprofit funded by auto insurers. On 30 August 2022, it published its first night ratings of pedestrian automatic emergency braking, for 23 vehicles. IIHS notes that three-quarters of pedestrian deaths occur at night. On a track kept below 1 lux, it ran an adult crossing the road and an adult walking along it, with low and high beams. Pre-Collision Assist with Automatic Emergency Braking is standard on the 2022 Ford Mustang Mach-E. The Mach-E avoided the crossing dummy at 12 and 25 mph and the walking dummy at 25 mph with both beams. IIHS reports that it slowed substantially at 37 mph with both beams, mitigating the impact. It was one of four vehicles rated superior. IIHS limits ratings of camera-based systems to the headlights it tested. Ford wrote in July 2020 that Mobileye's EyeQ chips and vision software would support Pre-Collision Assist on its next-generation vehicles, the Mach-E among them. No crash avoided on public roads is reported.

Insurance Institute for Highway Safety. Few vehicles excel in new nighttime test of pedestrian autobrake. News release, 30 August 2022, section How they fared.
The Camry, Highlander and Mustang Mach-E, which also earn superior ratings, avoided hitting the dummy in the crossing scenario at both test speeds and in the 25 mph parallel test with both low and high beams.

Press release, by the makers.
Ford Motor Company. Ford and Mobileye Expand Relationship to Offer Better Camera-Based Collision Avoidance in Global Vehicles. News release, 20 July 2020, archived copy. Ford names the Mustang Mach-E among the next-generation vehicles that use Mobileye's EyeQ chips and vision-processing software.
Used to help precisely identify what the windshield camera in a vehicle can see – including lane markings, traffic signs, pedestrians and other vehicles – Mobileye’s technology will support features such as Lane-Keeping System, Auto High-Beam headlamps, Pre-Collision Assist with Automatic Emergency Braking and Intelligent Adaptive Cruise Control, as well as Active Drive Assist hands-free driving coming to the all-new Mustang Mach-E and all-new F-150.

Mobileye. What is FMVSS 127 and how can Mobileye help automakers comply? Blog post, 9 October 2025. It describes Mobileye's current camera-only emergency braking on its EyeQ6L chip and adds that vehicles with EyeQ4 and EyeQ6 chips can take the software by update.
This is achieved with the support of the Mobileye EyeQ™6L SoC equipped with our proprietary AI models that have been trained on large volumes of real-world driving data.

AI system
- Workflow
-
Pre-Collision Assist with Automatic Emergency Braking was standard on the 2022 Mach-E. IIHS kept ambient light on the track below 1 lux and tested with low and high beams. Scores came from the average speed reductions in five runs of each test on dry pavement.
Follow-up
- Conditions for replication
-
The car has the headlights used in the test, since IIHS rates camera-based systems only with those headlights. The pedestrian crosses the road or walks in the car's lane, as in the tested scenarios.

- Sector
-
Road vehicle crash avoidance.
- Purpose
-
Ford built Pre-Collision Assist with Automatic Emergency Braking, part of Ford Co-Pilot360, to warn the driver and brake automatically when a collision with a vehicle or pedestrian is likely.
