(CBS) - The Insurance Institute for Highway Safety is out with new crash test results for small cars.
The Mini Cooper-Countryman is the only small car to receive a good rating in the crash tests. The Institute performed its newer "small overlap" test on 12 small cars. The 40-mile per hour crash simulates what happens when the front corner of the car collides with another car or tree. It's the first time the institute performed this particular test on electric and hybrid cars.
The Ford C-Max hybrid and electric Chevy Volt received acceptable ratings. The Volt was the only car in the test group to earn the 2014 Top Safety Pick plus the institute's highest award.
"The Top Safety Pick Plus also rewards vehicles that have forward collision warning systems and systems with autonomous breaking, which is available on the Volt," says Joseph Nolan, IIHS Senior VP of Vehicle Research.
The Volt's electric competitor -- the Nissan Leaf rated poor. The Fiat 500-L, the Nissan Juke and Mazda 5 were the worst performers. The IIHS says the Mazda 5 was also the only 2014 model car to earn a marginal rating in its side impact test -- one of the Institute's 4 other crash tests.
