Liuzzi, 29, was available after being released from his Force India contract at the end of last season, and tested with the Spanish team in Barcelona last month with a view to securing a drive alongside Narain Karthikeyan.
Liuzzi made his F1 debut in 2005 replacing Christian Klien at Red Bull and securing his first point with eighth place on his debut at Imola.
The Italian then moved to Red BullÃ¢â‚¬â„¢s junior team Toro Rosso for 2006 and 2007, with an impressive performance at the 2007 Chinese Grand Prix to finish sixth.
Liuzzi moved to Force India in 2009 and equalled his best finish with sixth place at the inaugural 2010 Korean Grand Prix in October, finishing the season with a career-best 21 points.
Ã¢â‚¬Å“I am really happy to have signed this agreement with Hispania Racing,Ã¢â‚¬Â said Liuzzi. Ã¢â‚¬Å“I never lost hope to be in Formula One as I knew I have the experience and the right attributes for a young and ambitious team.
Ã¢â‚¬Å“I face a new challenge now and this excites me. I also face a lot of hard work in guiding Hispania Racing through the development of our new car. I am extremely grateful to JosÃƒÂ© Ramon Carabante and to Colin Kolles for giving me such an opportunity.”
Hispania team principal Colin Kolles added: Ã¢â‚¬Å“I have known Tonio for many years as he raced with me in lower categories. He is a very professional driver who will bring a lot of benefits to the Team.
Ã¢â‚¬Å“I am convinced about his skills to develop a car and his speed. He has shown this in the past having contributed to a large extend developing and moving a back grid car to the front.
Ã¢â‚¬Å“I had the pleasure of working with him and I am very happy and proud to have him racing with Hispania Racing.Ã¢â‚¬Â
