AUSTIN, Texas (AP) — NASCAR is set to race the Circuit of the Americas for the first time and all eyes are on Chase Elliott and a wet weather forecast that could make the inaugural Texas Grand Prix a wild one. The Cup Series’ defending champion will start Sunday as the favorite given his career mastery of road courses. And he needs a win. NASCAR’s season of parity of 10 winners in 13 races has so far excluded him. NASCAR is racing for the first time at the track built for Formula One.
