Vitantonio Liuzzi earned two points for the Mercedes-powered Force India team with ninth, and former Brawn driver Rubens Barrichello took the final point with 10th on debut for Williams.
Recent reports suggest that Sauber, Force India's Swiss-based rival, is for sale and over the past two months Mercedes has offloaded 40% of its team to motorsport entrepreneur Toto Wolff and triple F1 champion Niki Lauda.
