Yesterday, Tesla Motors put out a post on the effectiveness of its Bioweapon Defense Mode found on the Model X & S.

Late last night, the electric automaker released a brief video showing Bioweapon Defense Mode in action in a Model X in smoggy Beijing.

Video description:

"Watch air pollution levels inside Model X drastically drop when we turn on Bioweapon Defense Mode in Beijing."

According to Tesla, "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.”
