XLR-8 (pronounced "accelerate") was a suspended roller coaster located at the defunct Six Flags AstroWorld. Manufactured by Arrow Huss at a cost of $3.2 million,[1] the ride opened to the public in 1984, where it operated until the park's closure in 2005. It was one of Arrow's first attempts at producing a successful suspended coaster following troubles with The Bat at Kings Island, which operated briefly from 1981 to 1983.
