The Toyota Sienna stumbled, the Chrysler Pacifica turned in an acceptable performance and the Honda Odyssey finished strong in the Institute’s passenger-side small overlap front crash test.

The 2018–19 model minivans are the latest group to be put through the passenger-side small overlap test. A small overlap crash occurs when just the front corner of the vehicle strikes another vehicle or an object such as a tree or utility pole. IIHS began rating vehicles for occupant protection in a driver-side small overlap front crash in 2012 and added the passenger-side test last year to make sure occupants on both sides of the vehicle get equal protection.

Manufacturers are making fast improvements to secure a good or acceptable rating in the passenger-side test, one of the requirements to earn a 2018 TOP SAFETY PICK+ award.

“In our latest passenger-side tests, we didn’t find any performance issues with safety belts or airbags like we did when we evaluated small and midsize SUVs earlier this year and midsize cars last year,” says David Zuby, the Institute’s chief research officer. “Instead, we saw some structural deficiencies on the right side that still need addressing.”

The Pacifica earns an acceptable rating in the passenger-side small overlap front test, and the Odyssey earns a good rating. Results for the Odyssey first were released in September 2017. The Sienna earns a marginal rating in the passenger-side small overlap test.
