To earn a "good" rating in both versions of the side test, the occupant compartment of the vehicle must hold its shape, the crash-test dummies must not show signs of severe injuries, and the side airbags and seat belts must "prevent the dummies' heads from making hard contact with the interior of the vehicle."
The 10 vehicles to receive a "good" rating were the Ford Explorer, Infiniti QX60, Lincoln Aviator, Mazda CX-9, Nissan Pathfinder, Subaru Ascent, Toyota Highlander, Volkswagen Atlas, Volkswagen Atlas Cross Sport and the electric Volkswagen ID4.
The Buick Enclave and Chevrolet Traverse earned "acceptable" ratings, while the Honda Passport, Honda Pilot, Hyundai Palisade, Jeep Wrangler four-door , Kia Telluride and Nissan Murano earned "marginal" ratings.
IIHS President David Harkey told Automotive News that he was pleasantly surprised with the results of the test because when the institute ran the new test on small crossovers in the fall, only one out of the 20 tested vehicles received a "good" rating.
"It means that the automakers have already started to make improvements in their vehicles that can prevent these more severe collisions and injuries," Harkey said. "And so we are encouraged that we think the automakers will continue to progress pretty rapidly at improving their vehicles and providing even more safety for consumers."
