Citroën Racing has announced it is expanding to four cars full time in the WTCC for 2015 to include Chinese driver Ma Qing Hua alongside reigning champion Jose Maria Lopez, Sebastien Loeb and Yvan Muller. The former HRT F1 test driver only raced with the team on a temporary basis last year, but certainly made an impression when he did, taking a podium in his home race and then becoming the first Chinese driver to win an FIA world championship race at Moscow Raceway. “I’m really happy to be carrying on with Citroën. As soon as I arrived in the team, I felt like part of a family,” the 27 year-old said. “Competing in every round of the championship marks a new stage in my career. I know that Citroën are counting on me, and I promise to give it my all.” The WTCC teams' first test begins this Friday. Given that he’ll be with the same team and car (Citroën C-Elysée) which dominated last year, his chances of further success look good when the season starts in Argentina on March 8th.
