Team boss Olivier Quesnel said he feels that 2010 has been Citroen's best in the World Rally Championship after Sebastien Loeb secured victory in the season ending Wales Rally GB.
Loeb took his eighth win of the campaign in the Welsh forests to give Citroen ten victories in 13 events, after fellow Frenchman Sebastien Ogier also won twice.
As well as securing the drivers' title with Loeb, Citroen also secured the manufacturers' championship once again in the final season for the current WRC cars.
After 36 wins in 56 starts, the current C4 WRC will be replaced by the new DS3 for the 2011 season.
“We've had a fantastic season with an impeccable performance from Sébastien Loeb, who has achieved an amazing feat by finishing all the events without ever having to use the SuperRally,” Quesnel said. “Sebastien Ogier has also had some good results. Apart from his mistake yesterday [when he crashed out of Wales Rally GB on Saturday], I'll remember his two world championship victories. With ten wins in thirteen rallies I think that Citroen Racing has had its best season since it arrived in the world championship.
“We had two aims this year: continue winning with the C4 and prepare for the future by developing the DS3 WRC. We'll see in Sweden if we've done a good job, but I'm feeling confident for 2011.”
