Venezuelan racer E.J. Viso has signed to drive for Andretti Autosport in the upcoming IndyCar season, giving the team four cars in the series in 2013, owner Michael Andretti said Thursday. The deal announced Thursday will see the South American speedster join reigning series champion Ryan Hunter-Reay and fellow American Marco Andretti plus Canadian James Hinchcliffe in the Andretti line-up. "I could not ask for more than to get the opportunity to drive for a championship team," Viso said.
