By 1998 the attraction was still not open, but the concept art and videos shown in the Test Track Preview Center were updated. Guests also began to see Test Track merchandise available at a cart outside of the pavilion. Finally, in December of 1998 the ride was complete. The large mural on the outside of the building was removed, and soft openings for guests and cast members began. Although complete, Test Track broke down frequently, and took a long time to restart. This pushed back the opening of the attraction once again to March of 1999. After three years of construction, Test Track was officially dedicated on March 17, 1999. On hand for the event was NASCAR driver Richard Petty and supermodels Christine Brinkley, Angie Everhart, Carol Alt, and Frederique. Musical bands Earth, Wind and Fire and The Spinners played as fireworks flew over Epcot.
Since it's opening, the attraction has remained essentially the same. However in February of 2012, Disney announced that Test Track would be going under a lengthy refurbishment. General Motors' Chevrolet will assume sponsorship of the pavilion, and guests will now be able to design their own Chevrolet while in the queue. After designing their car guests will be see how their car endures through the various testing proceduresby boarding the "SimCars"". The post show is expected to allow guests to see new models of Chevrolets, as well as future Chevrolet products.
