If the zombie apocalypse does get triggered by a bioweapon attack, the safest place to be might not be the nearest bunker after all. If it's up to electric carmaker Tesla, the safest place anyone could be in is inside one of its vehicles, specifically its crossover SUV, the Tesla Model X.

In a recent test, Tesla stated that the Model X's Bioweapon Defense Mode, which uses a HEPA air filtration system and which critics argued was simply a marketing statement, was so powerful, it actually cleaned the air both inside and outside the vehicle.

Tesla was able to do this by placing the green vehicle inside a large bubble that is saturated with extreme pollution levels. The air was so dirty inside the bubble that it is about 8,200 percent above the EPA's "good" air quality index. Indeed, the air inside the bubble was really bad. Toxic, even.

In just about 120 seconds, the Model X's HEPA filtration system was not only able to keep the air inside the car's cabin clean, it was also able to lower the pollution levels in the bubble that the instruments detecting the harmful particles in the air were not able to detect anything at all.

In fact, Tesla even stated that the testers inside the bubble were eventually able to remove their gas masks and breathe in fresh air which, just minutes ago, was so dirty that breathing it in would be harmful to the lungs.

"The Bioweapon Defense Mode is not a marketing statement, it is real. You can literally survive a military grade bio-attack by sitting in your car," Tesla said in a statement.

The results of the Model X's Bioweapon Defense Mode are indeed remarkable and is probably part of the firm's efforts at silencing critics who have alleged that the feature is simply a marketing stunt. After all, with Tesla attempting to breach markets worldwide where pollution is a huge problem, such as China, a feature such as the Model X's Bioweapon Defense Mode would undoubtedly be a good selling point.

Besides, who can deny that the name of the feature alone is already extremely cool?
