While both are high-speed thrills, Test Track is technically the faster ride, reaching a top speed of 65 mph during its outdoor "speed loop" at EPCOT. TRON Lightcycle / Run at Magic Kingdom, by comparison, tops out at approximately 59 mph during its initial outdoor launch. However, many riders find TRON to be more "intense" because of its unique motorcycle-style seating and the sheer force of its launch, which hits top speed in seconds. In 2026, visitors often debate which is better for a "need for speed" fix: Test Track offers the raw sensation of a fast convertible on a highway, while TRON provides a sleek, futuristic rush. If your goal is purely the highest number on the speedometer, Test Track remains the undisputed champion of the Walt Disney World resort.
