In a giant factory surrounded by mountains covered in snow, a lift lowers the steel bodies of cars onto the start of an assembly line.

They've just been welded together by robots - there are 690 working in this factory.

Next an army of human workers in red trousers and white t-shirts will transform these steel shells into finished cars.

One of these vehicles drives off the end of the assembly line every minute, flashing its headlights.

This is the European factory of Korean car company Kia, just outside the city of Zilina in the north of Slovakia.
