Detroit • The four-door Mini Cooper Countryman was the only one of 12 cars to earn a top rating of "good" in new frontal crash tests.
The Nissan Leaf, Nissan Juke, Fiat 500L and Mazda5 wagon all fared worst in the tests performed by the Insurance Institute for Highway Safety, an Arlington, Va.-based safety group that's funded by insurers.
The Chevrolet Volt, Ford C-Max, Mitsubishi Lancer, Scion FR-S and Subaru BRZ all got the second-highest rating of "acceptable." The Hyundai Veloster and Scion xB were a notch below that, with "marginal" ratings.
The small overlap front crash test, introduced in 2012, replicates what happens when 25 percent of a car's front end strikes a rigid object at 40 miles per hour. It's a difficult test because a small area of the car's front end must absorb and manage the energy from a severe, high-speed crash.
