The team was forced to change their plan to test in Monza, due to the snow that covered the Italian track, and headed for the Slovak Republic.
Huff and his team-mates Marc Basseng and René Münnich completed more than 500 kilometres between Wednesday and Thursday, focusing on set up, qualifying simulations and starts.
Huff said: “I'm very pleased to be joining the team. They are World Champions themselves and so we have a very strong team and a great car for the yea. I'm very excited. It's going to be a big challenge, but it’s nice for me.”
Basseng added: “The level of competition in WTCC is actually very high and we are a new team. We definitely have to learn, but we have a good driver line up, with Rob Huff as the World Champion. He has a lot of experience and can help the team to improve quickly. So we hope that we can be on the front of the grid from the beginning.”
