Unlike some SUVs, the all-electric Tesla Model X is not prone to rolling over. As a matter of fact, recent testing conducted by the electric automaker reveals that the Model X is almost impossible to roll.

During official testing conducted by the National Highway Traffic Safety Administration (NHTSA), the Model X was awarded a five-star overall rating and given five stars in every individual category during crash testing. Of particular interest was the rollover test which the Model X passed with flying colors and was awarded five stars in.

To show just how difficult it is to get the Model X to roll, Tesla has posted a video on its official Twitter showing the SUV being shoved sideways into a massive box of sand to see if it will flip. On three occasions, the SUV looks to be on the verge of rolling but at the last second, manages to right itself. In the final test, the Model X actually starts to roll onto its roof but somehow flips back around.

Of course, it isn’t entirely surprising how difficult it is to roll the Model X. After all, the vast majority of its weight is centered around the floor where the heavy battery pack and electric motors can be found.

As well-rounded as the Model X may be, it is still very much restricted to the wealthy. However, Tesla is currently working on a much more affordable SUV, dubbed the Model Y, which should make electric SUVs accessible to the masses.
