Recent developments in models with warped extra dimensions have opened new possibilities for vectorlike quark studies at hadron colliders. These new vectorlike quarks can mix sizably with light standard model quarks without violating low energy constraints. We perform a model-independent analysis to determine the Tevatron reach in the search for new quarks. We find that the Tevatron has great potential to observe such quarks via their electroweak single production due to their mixing with valence quarks. With 4(8) fb-1 integrated luminosity, one may reach a 5sigma statistical significance for a heavy quark of mass 580(630) GeV if the heavy quark-Standard Model quark mixing parameter is order one.
