Some of the smallest cars sold in the U.S. fared poorly in overlap tests performed by an insurance industry group.

The  Insurance Institute for Highway Safety tested 11, 2014 models.

The  test, introduced two years ago, show what would happen to the front end if a car going 40 mph hit another vehicle or object.

None of the vehicles recieved the highest rating of "good" from the Insurance Institute for Highway Safety. The Chevrolet Spark earned the second-highest rating of "acceptable."

Six  cars including the the Nissan Versa - got the lowest rating of "poor."

While the Honda Fit and Fiat 500 scored high in other IIHS tests, they showed potential for driver injury in this test.

Car dealers said good scores help sell cars, but the law of physics puts small cars as a disadvantage over large cars during accidents.

Some small car owners said they still prefer their small, fuel efficient cars.
