Video: BMW gives factory tour of new 1-Series production

Modern car plants are fascinating to watch, but only a select few get to see what goes on inside. Now BMW gives us a preview of what occurs in one of its main factories in Regensburg, Germany when producing the new 1-Series.

Our tour guides for today are brothers, Freddy and Adam, who have appeared in BMW's recent 1-Series 'One Origin' advert.

The Regensburg factory is roughly 1.4 million square metres (15.1 million square feet) and employs around 9,000 workers that produce 1,100 cars per day.
