F1 cars are built in these British sheds

ZIRCOTEC

Sat on land consecrated by the original MG factory, Zircotec supplies some form of its nuclear-grade heat-protective coating technology to every F1 team on the grid.

And good lord, this stuff's clever. The coating protects vulnerable composite parts from getting damaged by heat - so stuff like carbonfibre brake guards, engine airboxes and floors -by applying a 0.3mm layer of ceramic.

But this isn't Ming Dynasty spec - it's a special concoction that only sticks to stuff when it's applied with a 14,000°c flame at twice the speed of sound. The method uses so much power that Zircotec has to have its own substation.
