Out of all seven newly rated 2018 models, none received a better than "acceptable" rating for structure, IIHS said.
Across the board, the Outlander Sport received a marginal rating and the Ford Escape earned a poor rating in part for allowing "too much intrusion into the occupant compartment" on the passenger-side, IIHS said.
"The Escape struggled in the test as intruding structure seriously compromised space for the right-front passenger," IIHS said. "Intrusion measured ten inches at the upper door-hinge pillar, compared with 5 inches in the driver-side test."
Crash test dummy measurements for the Escape indicate that right hip injuries are likely if a real-world crash of this level were to occur, the IIHS said.
"In 2017, Ford redesigned the driver side of the Escape to perform better and protect better and so they have an acceptable rating on the driver side, but they didn't make the same kind of structural changes to the passenger side," said Mueller.
"There were a number of things that were problematic to the Ford Escape that contributed to that poor passenger side rating," said Mueller.
