As an advocate of the unified process of automobile odor evaluation in Germany, Audi set up a special odor research and development department as early as 1985, which played a leading role in the field of automobile odor. On September 20th, 20 10, FAW-Volkswagen Audi brand cooperated with Odor Store, the most powerful force in the domestic odor marketing field, for the first time, and conducted a unique Audi odor tour in Beijing, exploring the enterprising atmosphere of Audi brand with the media and guests, and deciphering the unknown R&D story of Audi's "nose team".

Audi's R&D department attaches great importance to the sensory experience in the R&D process, and strives to convey the user's pleasant driving experience through the five senses. It can be said that compared with those tangible assembly standards or research and development achievements, "smell" is often the most easily overlooked part, but it is also the part most closely related to the life of people and cars. Smells are everywhere, and there are more than 10 thousand kinds of smells that human beings can recognize and remember. At the same time, smell is also called the "best clue" to trace the past. Compared with other perceptual experiences, the sense of smell is more likely to induce emotions. Therefore, derivative aromatherapy is also used in psychotherapy to help people overcome anxiety. Fragrance marketing, olfactory recognition system and personalized olfactory customization are being accepted and used by more and more domestic enterprises.
