No, Test Track is technically faster than Guardians of the Galaxy: Cosmic Rewind, though they offer very different sensations of speed. Test Track remains the fastest attraction at Walt Disney World, reaching a top speed of 65 mph (105 km/h) during its outdoor high-speed loop. In comparison, Cosmic Rewind reaches a top speed of approximately 60 mph (97 km/h) during its initial reverse launch and subsequent maneuvers through the "Galaxarium." While Test Track is 5 mph faster, many riders find Cosmic Rewind to be the more "intense" experience because it is an indoor roller coaster featuring a unique "omnicoaster" system where the vehicles rotate 360 degrees to point you at the action. The combination of darkness, rotating cars, and a high-speed reverse launch makes Cosmic Rewind feel incredibly fast, whereas Test Track's speed is more linear and traditional, mimicking the feel of an open-top car on a highway.
