Tesla Addresses Air Quality

When it comes to Tesla, things like âLudicrous Modeâ have a certain âweâre-not-taking-ourselves-too-seriouslyâ aspect to them. But the âBioweapon Defense Mode,â the name of the HEPA air filtration system thatâs used in the cabins of the Model S and the Model X sounds about as funny as your entire neighborhood suddenly being overrun by zombies.
âBioweaponâ? Sounds a bit extreme. Ludicrous, perhaps.
But Tesla has pointed out just how bad bad air really is.
The company cites figures from the World Health Organization on the amounts of PM2.5 levelsâthatâs particulate matter 2.5 micrometers in diameterâfound in various cities around the world. The average annual figures for various cities are: 56 Âµg/mÂ³ in Beijing, 25 Âµg/mÂ³ in Mexico City, 21 Âµg/mÂ³ in Hong Kong, 20 Âµg/mÂ³ in Los Angeles, 20 Âµg/mÂ³ in Berlin, 17 Âµg/mÂ³ in ParisÂ and 16 Âµg/mÂ³ in London.
Which doesnât mean a whole lot until you take into account that, again according to Tesla, a 2013 study conducted at Harvard indicates that people who live in those locales donât live as long as they might were they not breathing in all of those particles: population-averaged life expectancy reductions of 23 months in Beijing, 10 months in Mexico City, 9 months in Hong Kong, 8 months in Berlin and Los Angeles, and 7 months in Paris and London.
In developing their system they put a Model X in a sealed container and filled said bag with 1,000 Âµg/mÂ³ of PM2.5. They activated the Bioweapon Defense Mode and the results look like this:
Which is great for those who have the system in their Model S and Model X vehicles. But for the rest of usâparticularly those in the aforementioned citiesâbad air isnât particularly funny.
