Disney has just announced that the Test Track attraction at the Epcot park will reopen in the Fall! Here are some artist renderings from the Disney Parks Blog of what the attraction will look like when it opens to park visitors.
Guests will be able to design their own custom vehicles and then test it on the Test Track. After the ride, guests will be able to make a TV commercial featuring their concept car, and they will be able to race their concept car on a virtual track.
P.S. Did you notice that the ride is no longer sponsored by GM as a whole, but instead by Chevrolet?
