Kingda Ka uses a hydraulic launch mechanism that has a motor capable of producing 20,800 horsepower. It accelerates the train to 128 miles per hour (206 km/h) in 3.5 seconds, subjecting riders to about 1.7 g's of acceleration. The launch occurs on the straight track partially visible at the bottom of this picture.
