Two Nissan vehicles join the ranks of Top Safety Pick+ winners after earning superior ratings for front crash prevention.

The Nissan Sentra, a small car, and the Infiniti QX60, a midsize luxury SUV, both have good ratings in the Insurance Institute for Highway Safety’s five 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.

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, plus an advanced or superior rating for front crash prevention.

Nissan now has six vehicles that qualify for the award.
