No, TRON Lightcycle / Run is significantly different from Test Track, even though both are high-speed "Tomorrowland" style attractions at Disney World. Test Track is a "simulated car" ride that reaches a top speed of 65 mph on a flat outdoor loop; its intensity comes from speed and wind, but it does not have drops or coaster-style gravity elements. In contrast, TRON is a high-speed roller coaster that uses a unique "motorcycle" seating position where you lean forward and are secured by a back and calf restraint. While TRON is slightly slower than Test Track (topping out at 60 mph), it feels much more intense because of its "launch" out of the station and its vertical climbs and sharp banked turns under an illuminated canopy. TRON is much shorter—lasting only about 60 seconds—whereas Test Track is a longer, narrative-driven experience. If you enjoy the speed of Test Track, you will likely handle TRON well, but be prepared for a much more physical "coaster" sensation rather than a fast car ride.
