Test Track is a high-speed slot car thrill ride located in World Discovery at Epcot, a theme park at the Walt Disney World Resort in Bay Lake, Florida. The ride is a simulated excursion through the rigorous testing procedures that General Motors uses to evaluate its concept cars, culminating in a high-speed drive around the exterior of the attraction. The attraction soft-opened to the public on December 19, 1998, after a long delay due to problems revealed during testing and to changes in design. As a result, the attraction officially opened on March 17, 1999. Test Track replaced the World of Motion ride, which closed three years earlier in 1996. Originally, guests rode in "test vehicles" in a GM "testing facility" through a series of assessments to illustrate how automobile prototype evaluations were conducted. The highlight of the attraction is a speed trial on a track around the exterior of the building at a top speed of 64.9 miles per hour (104.4 km/h) making it the fastest Disney theme park attraction ever built. Test Track closed for refurbishment on April 15, 2012, and re-opened on December 6, 2012. It is now sponsored by the Chevrolet brand instead of General Motors as a whole. Guests now design their own car in the Chevrolet Design Studio. Then they board a "Sim-Car" and are taken through the "digital" testing ground of the "SimTrack". Throughout the ride, guests see how their designs performed in each test. After the ride, guests can see how their car did overall, film a commercial, race their designs, and have a picture taken with their own virtually designed vehicle with a chosen backdrop in the background. Test Track is located in World Discovery, formerly known as Future World East. History Test Track Presented by General Motors (March 1999–April 2012) World of Motion was an attraction that was located in the current building of Test Track and was sponsored by General Motors. When the sponsorship expired, GM was in the process of conducting lay-offs and cutbacks forcing the company to question whether or not to sign another sponsorship agreement. Upon deciding to sign another agreement, GM wanted Disney to construct a new ride on the site of World of Motion. The new ride would focus specifically around their automobiles, rather than the fanciful history of transportation from the pre-historic (animal transportation) to the modern age (automobiles, planes, etc.) that were
