If you ever visit the Spa race circuit it's almost impossible not to become entranced by the "Eau Rouge" corner.

Well, I say Eau Rouge, but technically I suppose it's the Eau Rouge and Raidillon combination. According to the Belgians, Eau Rouge is the left-handed kink at the bottom of the hill, leading into Raidillon - the uphill right hander and onwards. 

Truth be told, it’s one of the most spectacular sections of track that I’ve ever seen. Its sharp gradient and turns causes many cars to bottom out, sending out showers of glowing steel, titanium and alloy. Either that, or the wheels tuck up so hard in the arches that they rub, billowing grey smoke for a fraction of a second as the cars arc through the bend.

Eau Rouge isn't a corner that's taken slowly either, as cars come barrelling down the main straight in to it and try to maintain as much speed as possible, because after that complex there's a long straight, and they need a good run at it to set a good time. 

It’s not a corner that’s prone to processions, either. Bolder competitors regularly vie for position, brakes glowing and exhausts flaring, or seize the opportunity to slingshot past slower cars through the bend.
