Test Track is a track ride in Future World - Test Track at Epcot. While it's not the best, it is also recommended. The minimum height to ride is 40 inches.
You’ll tour an idealized automotive design facility in this ride sponsored by Chevrolet. While you wait to board, you’ll get to choose some of the elements of a new car that will be tested during your ride. Once on board, you’ll ride in a six-seat “test vehicle” as unseen engineers test your car for traction, response, efficiency, and, of course, speed. The finale blasts you through the wall of the test facility for a high-speed ride around the outside of the Test Track building.
