The Audi Nose Team is a thing, and no, I'm not making this up. 

For 35 years, Audi has relied on a team of scientists to ensure that the interiors of their luxury vehicles smell as neutral as possible. The department works to determine that the materials and substances used in assembly won't leave a noticeable smell and that outside heat won't create foul odors from forming in the cabin. If the smell doesn't pass their test, it's back to product design for a do-over. Don't believe me? Give this video a watch.

Can you imagine the devastation if one of these guys caught a head cold?!

I would hope that the science lab gets a bit livelier than that, but something tells me that these German scientists have zero desire for horseplay. I could see some impish junior scientist swapping one of the "upholstery scent" jars for something particularly rancid to spring on his colleagues.

All the same, I'm actually quite impressed that Audi actually thought to dedicate an entire department to how a car smells, and I do appreciate the dedication. After all, the sense of smell is the strongest of the human senses, and the last thing you want is a headache-inducing odor assaulting your olfactories as you drive through the city. 

From now on, I will take a deep inhale of every new car I sit in for my own personal quality control. If a car manufacturer deems it important, that's a worthy enough reason for me.
