It's official – Australia's V8 Supercars series is set to bash fenders in Austin, Texas in 2013. The news comes hard on the heels of the Austin city council approving the United States Grand Prix Formula One race at the Circuit of the Americas. The FIA-sanctioned touring car series has signed a five-year contract and the two 124-mile (200-km) races will be televised live on SPEED. The 3.4-mile Circuit of the Americas will also play host to MotoGP bike racing, having sewn up that series from 2013 to 2022. Check out the full details in the press release after the jump.
