Sep.21 (GMM) Axed Toro Rosso driver Scott Speed is set to kick off a new career in American tin top racing.

The Californian, who was replaced by Sebastian Vettel recently following a falling out with his F1 team bosses, will drive a Red Bull-sponsored car in the ARCA race - a stepping stone to the NASCAR series - at Talladega next month.

"I come from a completely different world of racing, so there's no doubt it's going to be a challenge learning how these cars handle," he said. "But I'm ready to get out there and see what I've got," Speed said.
