Nanjing, China - While Western drivers like the 'new car' smell fresh off the production line, Chinese would rather their cars didn't smell of anything - a cultural divide that's testing car makers seeking an edge to revive sales in the world's biggest auto market.

At Ford, for example, 18 smell assessors - dubbed "golden noses" - at its research plant outside the eastern city of Nanjing test the smell of each material that goes inside a Ford car to be sold in China and around Asia.

The China smell test isn't unique, but illustrates the lengths automakers go to to attract buyers in markets where consumer attitudes vary widely.

Andy Pam, material engineering supervisor at the Ford facility, which employs about 2300 people, said: "In North America, people want a new car smell and will even buy a 'new car' spray to make older cars feel new and fresh. In China it's the opposite."

Top concern

The smell of a new car in China can have a huge effect. A 2016 JD Power report showed unpleasant car smells were the top concern for Chinese drivers, ahead of engine issues, road noise or fuel consumption.

The smell assessors at Ford, whose sales in China are down seven percent in 2017, carry out 300 tests a year, a third more than their counterparts in Europe. They rate the odour of all materials used in a car from "not perceptible" to "extremely disturbing".

Pungent materials - from carpets to seat covers and steering wheels - are noted as smelling of anything from "burnt tire" and "bad meat" to "moth balls" or "dirty socks". Some are sent back to the supplier.

Seats for Ford cars in China are stored in perforated cloth bags to keep them ventilated before being installed, as opposed to plastic wrapping in the US market where customers are less concerned about chemical smells.

'Pretty pungent'

Tom Lin, a 24-year-old high-school teacher in Zhejiang province who bought a local Roewe brand car in October 2016, said: The smell inside the car can often be pretty pungent,"

There was still a bit of an odour six months later, he said.

"With the next car I buy, I'm going to take more care to check out any odd smells." he said.

Smell is just one factor for automakers to get right in China, where picky buyers are always looking for fresh car models and Beijing is making a big drive towards new energy vehicles.

Extra edge

In a slower market makers are looking for an extra edge to appeal to buyers Local rivals Geely and BYD have air filters to protect drivers from China's harmful air pollution, and BMW says it is adding larger touch screens and tweaking colours to appeal to Chinese buyers.

Smell is key though, reflecting a wider concern in China about chemicals and pollution.

Don Yu, general manager at CGT, which makes materials to cover car seats and dashboards for General Motors, Volkswagen and Ford, explained: "When I lived in the United States I might look at the suspension or the engine. In China, though, people open the car and sit inside, if the smell isn't good enough they think it will jeopardise their health."

Strict routine

For Ford's "golden noses" that means a strict routine. Testers undergo a tough selection process, proving themselves on blind smell tests before being chosen.

One of the team, 33-year-old Amy Han, said: "We have to have very healthy habits; we can't smoke, we can't drink."

She avoids spicy food and doesn't wear nail polish, strong perfume or even a leather jacket to keep her sense of smell sharp.
