Auto Special: Infiniti's luster: Local production of top luxury

One thing that Wang Yuanpo must do before he fires up the paint shop every day is to help his 13 spray robots wear fabric sleeves to keep the dust away. It is one of the innovations at the Infinite's Xiangyang plant, Hubei province, to ensure the locally produced Infiniti Q50L model meets the same high specs as the imported Q50.

The 27-year-old Wang, who was born in a village in Shaanxi province, said he believes exterior finish on a luxury car should have a mirror sheen and "the Infiniti model we are producing also must have such a feature".

Spraying up to 60,000 revolutions a minute, robots at the Infiniti's production base can better atomize the paint. But the high voltage used by robots attract impurities that then pollute the car surface.
