Two vehicles from Nissan Motor Co. — the 2016 Nissan Sentra and Infiniti QX60 — have joined the ranks of Top Safety Pick+ award winners after drawing “superior” ratings for front crash prevention, the Insurance Institute for Highway Safety said.

Both models also earned “good” ratings — the highest available score — in the five IIHS crashworthiness tests. Their optional front crash prevention systems only recently became available for testing.

In the 12 mph IIHS track test, the Sentra avoided a collision completely. In the 25 mph test, the car’s impact speed was reduced by an average of 10 mph, IIHS said. The QX60 avoided a collision in both tests.

Both vehicles also received credit for forward collision warning components in their front crash prevention systems that meet National Highway Traffic Safety Administration criteria.

To qualify for Top Safety Pick+, the institute's highest award, a vehicle must earn “good” ratings in the small overlap front, moderate overlap front, side, roof strength and head restraint tests as well as an “advanced” or “superior” rating for front crash prevention.

With the addition of the Sentra and QX60, Nissan Motor Co. has a total of six vehicles that qualify for the award.
