Small Car vs Big Car Crash Test – Video
In the first of the two demonstration tests, a used 2016 Kia Sorento, a midsize SUV, and a 2018 Kia Forte, a small car, collided with each other. In the second test, a used 2015 Toyota Avalon, a large car, was paired with a 2018 Toyota Yaris iA, a minicar. Both the Sorento and the Avalon are among the IIHS Best Choices for teens. The Forte and the Yaris iA have good ratings in the five IIHS tests relevant to driver protection, and the Forte is a 2018 TOP SAFETY PICK+ winner.
In each test, the vehicles traveled toward each other at 40 mph, with 50 percent of the smaller vehicle’s width overlapping the larger vehicle. Forces on the driver dummies in the smaller vehicles were much greater than those in the larger vehicles.
Measurements indicated a high likelihood of head injuries for the driver of both the Yaris iA and the Forte in a real-world crash of the same severity. Right leg injuries would be likely in the Forte and possible in the Yaris iA. Neck and chest injuries would also be possible for drivers of both vehicles, and left leg injuries would be possible in the Forte.
In contrast, the Avalon and Sorento had mostly good injury measures, aside from a possible right leg injury in both.
The structures of the Forte, which weighs 928 pounds less than the Sorento, and the Yaris iA, which weighs 1,033 pounds less than the Avalon, didn’t hold up as well against the larger vehicles as in the car-to-barrier tests that IIHS ratings are based on.
In the crash with the Sorento, the Forte had an acceptable structural rating, with maximum intrusion of 8 inches at the left toepan. In the crash with the Avalon, the Yaris iA also had an acceptable structural rating, with maximum intrusion of 10 inches at the center toepan. In contrast, the Forte and the Yaris iA earn good structural ratings in the moderate overlap and the driver-side small overlap front crash tests.
The Avalon and the Sorento had good structural performance in the paired crashes.
“Bigger vehicles provide greater protection,” Cicchino says. “If you’re riding in one of the smallest vehicles on the road, you’ll be at a disadvantage in a crash with almost any other vehicle around you.”
