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. The ride lasts 28 seconds from the start of the launch to the end of the brakes. The track is 3,118 feet (950 m) long.
