The Insurance Institute for Highway Safety is updating its vehicle-to-vehicle front crash prevention test to address crashes that occur at higher speeds and those in which the struck vehicle is a motorcycle or large truck. Only one of the first 10 small SUVs evaluated earns a good rating.
The Subaru Forester is the only small SUV to earn a good rating in the updated test. Two others, the Honda CR-V and Toyota RAV4, are rated acceptable. The Ford Escape, Hyundai Tucson and Jeep Compass earn marginal ratings, while the Chevrolet Equinox, Mazda CX-5, Mitsubishi Outlander and Volkswagen Taos are all rated poor.
The original vehicle-to-vehicle front crash prevention evaluation was developed when the technology was relatively new, so the performance requirements only addressed low-speed crashes. By the time the original evaluation, with test runs at 12 and 25 mph, was discontinued at the end of 2022, all tested vehicles were earning the top rating of superior.
While real-world data indicate that front crash prevention is eliminating higher-speed crashes, the original test didn’t provide a way to gauge the performance of specific systems at those higher speeds.
Additional IIHS research also showed that today’s systems are less effective at preventing crashes with motorcycles and medium or heavy trucks than they are at preventing crashes with other passenger vehicles.
To address those issues, instead of the earlier 12 and 25 mph speeds, the updated test includes trials run at 31, 37 and 43 mph (50, 60 and 70 kilometers per hour). In addition to a passenger car target, it examines performance with a motorcycle target and a semitrailer. As a result, the new evaluation reflects a substantially greater proportion of police-reported front-to-rear crashes, including many that are more severe.
