The reason why you can't hear the motor is because we are using electromagnets. This means while acceleration is poor (the car weighs between 10t (empty) and 18t (full)) very high speeds and very high lift shafts are possible (this one is 870m tall). Specs: Maximum speed: 25.65 m/s, 92.34km/h, 57.37 mph. Acceleration: 0.9m/s^2, 0.091G
