Tesla testing Bioweapon Defence Mode that can save drivers from a 'military-grade bio-attack'

American automotive company, Tesla, is testing its Bioweapon Defence Mode, a state-of-the-art air filtration system, which is designed to protect drivers from harmful emissions.

Both the Model X and the new Model S cars will come equipped with the new defence mode called Hepa, which according to Tesla is capable of helping drivers "survive a military grade bio attack".

Tesla said in a blog: "Not only did the vehicle system completely scrub the cabin air, but in the ensuing minutes, it began to vacuum the air outside the car as well, reducing PM2.5 levels by 40%. In other words, Bioweapon Defense Mode is not a marketing statement, it is real.

Among the various places where the auto-maker tested its Bioweapon Defence Mode in the Model X include California's traffic-congested highways, major Chinese cities and cow pastures in central California.

The system reportedly cleanses the air both inside and outside the car. The Hepa takes inspiration from the air filtration systems used in hospitals, labs and the space industry, which is designed to eliminate "pollen, bacteria and pollution" before they can enter the car's cabin. Within the confines of the vehicle, the Hepa system works diligently to remove remote traces of harmful chemicals, ensuring that the air is clean and pure.

Air pollution is considered to be one of the most dangerous environmental health risks, according to the World Health Organization (WHO). Given the alarming levels of air pollution in developing countries like India and China, the new affordable Tesla Model S, if launched could prove to be immensely popular.
