Slinky Dog Dash, the family-friendly coaster at Disney's Hollywood Studios, reaches a top speed of 40 mph (64 km/h). In 2026, it continues to be one of the most popular attractions in Toy Story Land due to its unique "double launch" system. The first launch occurs at the very beginning of the ride, while the second happens midway through, where Slinky Dog "rewinds" slightly before springing forward through a series of "Go" rings. Designed by Mack Rides, the coaster is built to mimic the physics of a slinky stretching and coiling, providing a smooth but thrilling experience for guests who meet the 38-inch height requirement. Although 40 mph may seem modest compared to high-intensity "Giga-coasters," the open-air design and low-to-the-ground track layout make the speed feel significantly faster, especially during the banked turns and "camelback" hills that provide "airtime" for riders of all ages.
