A wing is one of the coolest things you can have on a road car. In some cases, they're just there for aesthetics, while in others, they actually provide downforce. Which is your favorite?
My favorite wing to appear on a road car is probably the one on the Koenigsegg Regera. The way in which the mechanism retracts from the body is unlike anything I've seen, using top mounts on the actual aero piece to improve airflow, while still sitting flush with the body when not in action.
Let Christian Von Koengisegg explain the active wing's revolutionary design in this video.
Now we'd like to know: Which car do you think has the coolest wing or spoiler? It doesn't have to be a new car, or even a fast car that necessarily needs a wing. It just has to be a factory piece of kit to fit the bill. Let us know in the comments below.
