4. Tower of Terror – Dreamworld, Coomera, Queensland, Australia Top Speed: 100 mph / 161 km/h
Tower Of Terror is a steel reverse freefall coaster. The six ton passenger vehicle, is electro-magnetically powered, accelerating its passengers rapidly to 160.9 km/h (100 mph) in seven seconds. The track then turns skyward, with the passengers pulling 4.5 G’s. The car climbs to almost 38 stories high. Following the climb, there is a 6.5 second free-fall before the 90 degree turn is executed in reverse. The vehicle then hurtles into the station where it comes to a rapid stop.

3. Dodonpa – Fuji-Q Highland, Fujiyoshida, Yamanashi, Japan Top Speed: 106.9 mph / 172 km/h
Dodonpa opened in 2001 and is a steel sit-down roller coaster with a compressed air launch. It is 52 metres (170 feet) tall, and has a launch speed of 172 km/h (107 mph), which is reached in less than 2 seconds. The launch is followed by a huge, sweeping, overbanked curve, giving riders a chance to catch their breath back, before they hit the 170 foot top hat; an element with some extreme negative G forces. The name ‘Dodonpa’ comes from the musical sound which is played to customers waiting to board it.

2. Top Thrill Dragster – Cedar Point, Sandusky, Ohio, USA Top Speed: 120 mph / 193 km/h
Top Thrill Dragster was the first “Strata Coaster,” loosely defined as a complete circuit coaster that is 400 to 499 feet tall. It was the last one to use lapbars instead of over-the-shoulder restraints due to mechanical problems. Shortly after reaching its maximum velocity in less than four seconds, the train begins its ascent up a 90-degree incline that has a 90-degree counter-clockwise twist that takes the train straight over the top of the 420 foot hill, where riders will experience significant airtime (zero g-forces). On the way down the other side, there is a 270-degree clockwise twist that leads into the magnetic braking section that brings the train to a swift but comfortable stop.

1. Kingda Ka – Six Flags Great Adventure, Jackson Township, New Jersey, USA Top Speed: 128 mph / 206 km/h
Kingda Ka is not just the fastest, but also the tallest roller coaster in the world. A hydraulic launch mechanism rockets the train from 0 to 128 miles per hour (206 km/h) in 3.5 seconds, pulling about 1.67 g’s. At the end of the launch track, the train climbs the main tower, twisting 90 degrees to the right before reaching a height of 456 feet (139.5 m). The train then descends 418 feet (127 m) straight down through a 270-degree spiral. Finally, the train climbs the second, 129 foot hill, producing a moment of weightlessness before being smoothly brought to a stop by the magnetic brakes. Due to the high speed and open nature of the trains, this ride will not operate in even light rain, as rider contact with rain drops can cause discomfort.
