After HRT collapsed at the end of the 2012 season, Ma moved to Caterham, continuing the role of Friday test driver whilst racing for their GP2 Series team for the season. In 2013 Chinese Grand Prix, he replaced Charles Pic to participate in the Free Practice 1 and became the first Chinese driver to drive in home Grand Prix session, but he was about 1.5 seconds off the pace to his teammate Giedo van der Garde and out of the 107% reference time to the quickest driver in Free Practice 1. Soon after the 2013 Chinese Grand Prix, Caterham team claimed that he would be replaced by Alexander Rossi for the rest of the 2013 season. In the 2013 Bahrain GP2 Series round, Alexander Rossi made his debut GP2 Series race and took a podium finish.
