The world’s steepest dive rollercoaster is set to open at Six Flags Fiesta Texas this summer.

Guests will soon be able to ride the eye-catchingly named Dr. Diabolical’s Cliffhanger.

Three 21-passenger trains will lift riders 150 feet in the air before dropping them down a 95-degree, vertical plummet at 60 mph.

It will be located in the Crackaxle Canyon Screampunk District of the park.

“Six Flags Fiesta Texas continues to push the limits of thrill and innovation as we prepare to introduce the world’s steepest dive coaster during our 30th anniversary season,” Park President Jeffrey Siebert said.

“Dr. Diabolical’s Cliffhanger joins an already stellar line-up of record-breaking roller coasters, rides, and attractions. With eight intense elements including dramatic inversions and extreme airtime, it will quickly become a fan favourite.”
