WTCC drivers treated American fans to a breathtaking show when the championship visited Sonoma and the United States.
Both races were eventful. Yvan Muller and Rob Huff in their Chevrolet Cruzes shared the victory honours and their results also made the fight for the world championship as hot as ever. The two Chevrolet drivers are now on equal points with only six races to go. Rob Huff is pictured above celebrating winning Race 2.
It's easy to predict that the battle will go to the wire at Macau once again.
Norbert Michelisz also had reasons to rejoice as the young Hungarian was a pain in the neck for the Chevrolet cars in both races and eventually claimed two podium results and stretched his leadership in the Yokohama Trophy.
Gabriele Tarquini and Alaim Menu tried their best and never gave up, but their hopes of achieving great results vanished when they collided at the start of the first race. The Italian had the consolation of a podium in Race 2 while the Swiss saw his hopes of staying in contention for the title fight seriously jeopardized.
Tom Coronel completed two great recoveries from 20th on the grids to eight and fifth; Alex MacDowall chased the topd rivers in both races and Tiago Monteiro finished twice in the points on his last appearance with Sunred before switching to Honda.
The championship now crosses the Pacific for the Asian tour that traditionally closes the season and includes stops in Japan, China and Macau. Rounds 19 and 20 will take place at Suzuka on 21 October.
