Dyne will compete in the No. 14 Barracuda Racing Ford Fiesta SuperCar.
"I am really excited to be expanding into GRC, and to do it with friends and partners like Barracuda and Austin Dyne is ideal," Herta said. “The car looks fantastic and the schedule and TV platform for the series is extremely compelling."
Dyne was named rookie of the year in the NASCAR K&N Pro Series West last year.
"It is exciting to be driving for Barracuda Racing this season," Dyne said.
"This is an outstanding team of people put together here and we are looking forward to getting the Red Bull Global Rallycross season underway in Barbados, May 18."
