The race itself belonged to Menu, who resisted the late race pressure of Priaulx, the Brit having spent most of the race gradually closing the gap down to the Lacetti as it seemed to fade in the latter stages.
Nonetheless, Menu retains the car's superb record around street circuits on the weekend that signals the Lacetti's final WTCC appearance before being replaced by the Cruze next season.
Behind the podium winners, Farfus battled to fourth position, ahead of Huff, who still only has a one point cushion over now Priaulx in the battle for third overall. Gene and Tarquini made it three SEATs in the top eight, while James Thompson has a great chance of ending a tough maiden season in the Honda Accord on a high as he starts from pole position in race two.
