Let's take a quick detour from the Echo and have a look at on my (other) favourite cars right now, the Nissan GTR.
A cool feature of the GTR is the twin vents/scoops on the bonnet. Ever wonder what they are?
Well wonder no longer! These guys are actually called NACA or NASA ducts. They're streamline air inlets that take in air but produces less drag than convential scoops.

Originally designed by the National Advisory Committee for Aeronautics (NACA) which later evolved to being National Aeronautics and Space Administration (NASA), these ducts are usually found on aeroplanes.
NACA ducts eventually found thier way into race cars obviously due to thier streamline design. Apart from finding them on bonnets and sidepanels, a common place you would see these ducts would be on a non-glass window of a race car. These ducts can provide air cooling for components or even cooling for the driver! Nice!

So wonder no more of those weird holes on cars and planes! And for your next track project, consider these ducts as streamline alternatives to scoops! Or if you have a useless quarter window, consider making that a dedicated NACA duct!

So cool! I wonder if I could make one for the Echo... Any back seat passangers wouldn't be too happy with wind blowing at them though lol.
