McLaren had the official unveil of its new production facility yesterday. I was among the group of journalists that got the tour and you can read more about it and the PM’s unexpected visit in the news story.

I’ve never been to the Norman Foster-designed McLaren Technology Centre before, and the new factory is as painfully clinical as you would expect. It’s a quite extraordinary feat to keep a car factory as pristine as the new Woking facility is and it’s very obvious on first impressions alone why McLaren is such a desirable place to work.

But while the efficiency and overall detail of the whole centre was weirdly inspiring, what impressed me more was the breadth and extent of the industries McLaren is involved in.

I’ve always been aware of the UK’s big Formula One presence and the ever-growing and vital car manufacturing that takes place here, but I was not aware of the number of other pies that McLaren has a squeaky clean finger in.
