The coaster train accelerates to its top speed in 5 seconds using a hydraulic launch system which generates a release velocity similar to that of steam catapults on an aircraft carrier.  Riders experience up to 1. 7 g of force during acceleration and up to 4. 8 g throughout the ride. The roller coaster track is 2. 2 km (1. 4 mi) in length, ranking it sixth in the world for steel roller coasters. Its shape was inspired by the legendary Italian racetrack Autodromo Nazionale Monza. Due to the high air speeds and thus risk of an impact with airborne particulates or insects, all riders are required to wear protective glasses similar to those used during skydiving. Formula Rossa surpassed Kingda Ka at Six Flags Great Adventure as the world's fastest roller coaster with Kingda Ka retaining the record of the tallest roller coaster in the world.
