Fury 325: Dare you ride the world's fastest, 153km/hr roller coaster with an 81-degree drop?

Standing six metres taller than the Statue of Liberty, capable of speeds just shy of 153 kilometres per hour, and with an 81-degree first drop, this is clearly not a theme park ride for those with a weak constitution.

Fury325 is the world's tallest and fastest "giga coaster", a term used for rides that have a drop of between 91 and 122 metres, with a height of 99 metres - that's five times taller than the Big Dipper, a notorious ride in the UK's Blackpool.

The ride will open to the public on March 28 at the Carowinds theme park in North Carolina, USA, which is investing a total of $US50 million ($A65 million) in new rides and ticketing systems.

Other well-known giga coasters include the 94-metre Millenium Force at Cedar Point amusement park in Sandusky, Ohio, and Steel Dragon 2000, at Nagashima Spa Land in Japan, which is 97 metres tall.

Fury325 is not the world's tallest coaster overall: that gong goes to the Kingda Ka, at Six Flags Great Adventure in New Jersey, which takes riders to the perilous height of 139 metres.

American theme parks have a history of opening ever-more outlandish theme park rides. Last year the world's tallest waterslide, at 51.38 metres, opened at Kansas City theme park.
