EPCOT Center's Never Built Future World Rollercoaster

 If you think Guardians of the Galaxy: Cosmic Rewind is the first rollercoaster planned for Epcot, think again. That honor actually goes to another Future World pavilion and not a reworking of the classic EPCOT Center attraction Universe of Energy. Any guesses as to what it could be?

Well, you'd be correct if you didn't think it was Test Track! But it was an attraction thought of for the Transportation pavilion, an early predecessor to the World of Motion. Imagineer Clem Hall designed the piece of concept art for that compound in Future World, but it never was built as designed. Fans never saw what could have been until years later. 

Look closely, and you'll see a four looped coaster track off to the back left side of the rendering before it heads back into the main structure. Shades of Tron, I'd say, decades before Shanghai Disneyland's "E Ticket" attraction came to be.
