The Tesla Model S may excel in its range, acceleration and tech capabilities but it looks like this model failed to impress when it comes to safety.

Back in 2011, the Model S received five stars from both the NHTSA and Euro NCAP and in 2013, it managed to claim the best results in crash testing since the US official brought on the current standards in 2011.

However, the Insurance Institute for Highway Safety has a different opinion. The Model S was rated “Good” in the moderate overlap front, side, roof strength, and head restraint/seat tests but only received the “Acceptable” rating when it came to the small overlap front crash test.

The issue was the seatbelt which failed to restraint the dummy’s head from hitting the steering wheel. So, as it failed to ace all five crash tests, Tesla did not receive a Top Safety Pick rating, once again.

To make it worse, the model is said to have poor headlights and marginal ease of use for its child-seat anchor latches. Although it comes with Advanced Autopilot system, the Model S fails to offer the front-crash prevention system needed to be eligible for a Top Safety Pick + award.

Meanwhile, the Chevrolet Volt and the Toyota Prius Prime both aced the tests and acquired the Top Safety Pick +. These plug-in hybrid models was rated “Superior” for their front crash prevention systems and the Prius was rated “Acceptable” for its headlights.
