A new roller coaster at Ohio's Cedar Point amusement park will be the highest and fastest such ride in the world, officials announced.

Speed on the Magnum XL 200 will exceed 70 mph when riders drop at a 60-degree angle from 201 feet above the ground on the first hill to less than 10 feet. The all-steel ride is to be unveiled next May."We wanted to go after the record for speed. But then we started calculating the force of gravity and angle of descent and realized it would have to be the biggest roller coaster," said spokeswoman Melinda Huntley.

The world's present highest roller coaster, the Shock Wave at Six Flags of Great America in Gurnee, Ill., has a first drop of 170 feet.

It will be Cedar Point's eighth roller coaster and its most expensive ride at $8 million.
