Bjørn Nyland finds himself in unusual Norwegian scenery (in fact he is in the U.S.) testing the Tesla Model X.

It turns out that a trip to Arizona is also a good opportunity to test Tesla's Bioweapon Defense Mode against manure (well, sh*t happens).

Of note:  The HEPA filtration option has just been added to the Model S as an option this week as part of a large refresh program for the car that also added a new front fascia (details)

Thankfully, the Bioweapon Defense Mode does the job and cleared the air when needed...or at least we believe so, as the video didn't give off any odor when we watched it.

"We were in the Tesla Model X driving west of Gila Bend in Arizona/US when we suddently felt this strong smell of manure. I grabbed my camera and enabled the bioweapon defense mode. The fans went full speed and created a pressurised cabin.

Normally, any smell inside the car will take several minutes to clear. But with the bioweapon defense mode, the smell disappeared within seconds. Very impressive!"

About the filter itself:

"Pollution Free, Inside and Out

A medical grade HEPA filter strips outside air of pollen, bacteria, viruses and pollution before circulating it into the cabin. There are three modes: circulate with outside air, re-circulate inside air and a bioweapon defense mode that creates positive pressure inside the cabin to protect occupants."
