Kevin Giovesi will complete the Lazarus team's GP2 line-up for its second season in the category.
Giovesi has raced primarily in Formula 3 for the past three years, taking three wins in Italy in 2012. He then tested for Lazarus over the winter before securing a place as Rene Binder's team-mate.
"The jump from F3 to GP2 is very high, but the test sessions in Jerez and Barcelona gave me a very good feeling, so I think I'm well prepared for racing in GP2," said Giovesi. "It will be a tough season. I will have to learn the circuits very fast but, with the help of the team, I can do a good job starting from the first race in Malaysia."
