When the Toyota Yaris iA, a minicar, and the Toyota Avalon, a large car, were crashed into each other, the smaller vehicle's structure didn't hold up as well as it should have.

Arlington, Virginia -- November 1, 2018 -- When it's time for a new driver's first set of wheels, many young people and their parents opt for something cute and inexpensive -- in other words, small. In terms of safety, that's a mistake, according to the Insurance Institute for Highway Safety (IIHS).

IIHS recently conducted a pair of front-to-front crash tests demonstrating what happens to small cars and minicars -- even new ones with stellar safety ratings --- when they collide with larger used vehicles from the same manufacturer. The results show the importance of size and weight when it comes to occupant protection.

In its regular vehicle ratings program, IIHS evaluates passenger vehicles of all sizes, and even minicars are eligible for the Top Safety Pick and Top Safety Pick+ awards. But the vehicles IIHS rates can't be compared across size and weight classes because the severity of the front and rear tests is determined in part by the vehicle's own weight. Consumers who opt for smaller vehicles are choosing a lower level of protection even if they purchase a Top Safety Pick winner.

Kia Sorento vs. Kia Forte and Toyota Avalon vs. Toyota Yaris iA

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 on which IIHS ratings are based.

The tests reinforce a message IIHS has been sending since it began publishing an annual list of recommended used vehicles for teens in 2014: An older, larger used vehicle is often a safer choice than a newer small vehicle that costs the same. All the models on the agency’s lists of recommended vehicles for teens are midsize cars or larger.

"We know safety is just one of the factors people consider when choosing a vehicle, but we hope parents will give it extra consideration when purchasing a vehicle for a teenager," says Jessica Cicchino, IIHS vice president for research. "Teen drivers are at greater risk, due to immaturity and inexperience behind the wheel."

"Bigger vehicles provide greater protection," Cicchino concludes. "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."
