Hello Karen! Welcome to the Disney Parks Moms Panel.
The speed and thrills of
Test Track at Epcot are made even more exhilarating knowing that you have designed the performance for your own vehicle.
The process for designing your vehicle initially begins in the queue where you go through the paces to create your ultimate dream vehicle. These schematics are loaded onto your
MagicBand or Admission Card. Once you reach the attraction itself, your creation will hopefully, be the one chosen and downloaded as the schematics for your attraction vehicle when you ride.
Upon exiting the attraction, there are several exhibits at the
Test Track SIMporium that will allow you to see scores for your vehicle, play additional games and make an ad for your vehicle. In my experience, the most recent car you designed is the one loaded onto the MagicBand or Admission Card. If you skip the design portion upon revisiting Test Track, the last car you designed will be the one accessed for the experience.
Happy Driving!
