Are you considering a new SUV and wondering how modern safety features truly perform? The video above provides a stark visual demonstration of Automatic Emergency Braking (AEB) systems put to the test by the IIHS (Insurance Institute for Highway Safety). As you witnessed, not all systems are created equal, and understanding these critical differences can significantly impact your family’s safety.
Today’s vehicles come packed with advanced driver-assistance systems (ADAS) designed to make driving safer. Among these, Automatic Emergency Braking (AEB) stands out as a crucial technology. It helps prevent or reduce the severity of collisions, particularly common rear-end crashes. This system works by detecting potential obstacles ahead and, if the driver doesn’t react in time, automatically applying the brakes.
Understanding Automatic Emergency Braking (AEB)
Automatic Emergency Braking (AEB) is a proactive safety feature that uses sensors like radar, cameras, or lidar to monitor the road ahead. When the system detects an imminent collision with another vehicle, pedestrian, or even a large animal, it first issues a warning. If the driver fails to respond, the system can automatically apply the brakes to avoid or mitigate the crash. This technology is a game-changer for reducing accidents and injuries on our roads.
The effectiveness of AEB systems can vary significantly between different car models and manufacturers. Research by the IIHS shows that front crash prevention systems with autobrake can cut the rate of rear-end crashes by a remarkable 50 percent. Furthermore, they reduce the rate of rear-end crashes resulting in injuries by 56 percent, highlighting their critical role in enhancing vehicle safety.
How IIHS Conducts Front Crash Prevention Tests
The IIHS is a non-profit organization dedicated to reducing deaths, injuries, and property damage from motor vehicle crashes. They conduct rigorous tests on vehicles to assess their safety performance, including how well their AEB systems prevent collisions. Their front crash prevention evaluation measures a vehicle’s ability to avoid or lessen the impact of a crash with another vehicle or a pedestrian.
In the tests shown in the video, vehicles are driven towards various stationary or moving targets, such as a semitrailer, an offset car, a centered car, or a centered motorcycle. The tests are performed at different speeds, including 43 mph, 37 mph, and 31 mph. Vehicles earn a rating of “GOOD,” “ACCEPTABLE,” or “POOR” based on how effectively their AEB system avoids or significantly reduces impact speed.
A “GOOD” rating indicates superior performance, often meaning the vehicle successfully avoided collisions in most test scenarios or achieved substantial speed reductions. An “ACCEPTABLE” rating signifies adequate performance, typically avoiding crashes at lower speeds or significantly slowing down before impact. A “POOR” rating, however, means the system performed poorly, failing to prevent crashes or offering minimal speed reduction, as unfortunately demonstrated by some SUVs in the video.
Examining SUV Safety: IIHS Test Results in Detail
The video showcased several popular SUV models and their performance in the IIHS Front Crash Prevention tests. These results are invaluable for anyone prioritizing safety when purchasing a new vehicle. Here’s a closer look at how some of these SUVs performed:
SUVs with a “GOOD” Rating for Automatic Emergency Braking
-
BMW X5: This luxury SUV demonstrated strong performance. In a 43 mph test with a semitrailer, it received an overall rating of “GOOD.” This indicates its AEB system effectively detected the large obstacle and initiated appropriate braking action.
-
Kia Sorento: The Sorento also earned a “GOOD” overall rating. It performed well in tests against an offset car target at 43 mph and a centered motorcycle target at 37 mph, showing versatility in detecting different types of obstacles.
-
Subaru Forester: Known for its safety features, the Forester lived up to its reputation. It achieved a “GOOD” rating in a 43 mph test with a centered car target and a 37 mph test with an offset motorcycle target. Subaru often integrates robust safety technology, and these results reinforce that commitment.
SUVs with an “ACCEPTABLE” Rating for Automatic Emergency Braking
-
Mazda CX-50: The Mazda CX-50 received an “ACCEPTABLE” overall rating across multiple tests. This included a 43 mph test with a semitrailer, a centered car target, and a centered motorcycle target. While not reaching “GOOD,” an “ACCEPTABLE” rating still means the system provides a decent level of crash prevention.
SUVs with a “POOR” Rating for Automatic Emergency Braking
-
Chevrolet Trax: The Trax unfortunately received a “POOR” overall rating. In a 37 mph test with a centered car target, its AEB system struggled, leading to an impact. This highlights potential limitations in its front crash prevention capabilities.
-
Audi Q7: Despite being a premium vehicle, the Audi Q7 was rated “POOR” in a 31 mph test with a centered motorcycle target. This outcome is concerning, especially given the vulnerability of motorcyclists on the road.
-
Chevrolet Tahoe: The larger Tahoe also performed poorly, earning a “POOR” rating in a 31 mph test with a centered motorcycle target. For such a substantial vehicle, effective AEB is critical to protect both its occupants and others on the road.
The Broader Impact of Advanced Driver-Assistance Systems (ADAS)
Automatic Emergency Braking is just one component of a larger suite of Advanced Driver-Assistance Systems (ADAS) increasingly common in new vehicles. These systems collectively aim to prevent accidents and protect occupants. Features like lane departure warning, blind-spot monitoring, and adaptive cruise control all contribute to a safer driving experience.
As technology advances, these systems become more sophisticated, integrating better sensors and artificial intelligence to improve their accuracy and reliability. For car buyers, understanding these features and their real-world performance is more important than ever. Always look beyond the simple presence of a feature; delve into independent safety ratings like those from the IIHS to gauge true effectiveness.
Choosing an SUV with Superior AEB Performance
When you are in the market for a new SUV, prioritize safety ratings from reputable organizations like the IIHS and NHTSA (National Highway Traffic Safety Administration). Do not assume that all models, even within the same brand, offer the same level of protection. The video clearly illustrates that performance can vary drastically.
Look for vehicles that earn “GOOD” ratings in front crash prevention tests. This indicates a robust Automatic Emergency Braking system capable of handling various real-world scenarios. Choosing an SUV with top-tier AEB can provide peace of mind and significantly reduce your risk of becoming involved in a collision.
