In its latest round of tests the Insurance Institute for Highway Safety found that diminutive cars still have issues with its challenging small overlap front crash test. This time out electric cars like the range-extender 2014 Chevrolet Volt and 2014 Nissan Leaf were tested for the first time with mixed results, while the Mini Countryman was the only small car in the group to earn a top grade in the test.
The Volt popped up on IIHS' scale of poor, marginal, acceptable and good with a score of acceptable, good enough for the Volt to be awarded a 2014 Top Safety Pick+ designation, the institute's highest award. The Leaf didn't fare as well in the 40-mph test designed to simulate a collision with another vehicle or a pole and earned a poor rating. IIHS observed intrusion in the lower and upper compartments indicating likely injuries to the left knee and left lower leg, while a left thigh injury would also be possible. Neither electric car had any issue with the batteries or electrical systems post-crash.
Ten other small cars went through this round of IIHS small overlap crash tests along with the Volt and Leaf, including the Mini Cooper Countryman and the Mazda5, which IIHS says is one of the worst-performing models the institute has evaluated in the small overlap test.
