Pons Racing and Oscar Tunjo have mutually decided to end their collaboration. The Colombian racer, who was scheduled to enter the 2015 World Series Renault 3.5 season with the Spanish operation, was forced to reconsider his plans due to budget concerns. Tunjo had made his WSR debut with Pons Racing during the 2014 season. The team, managed by Emilio de Villota, has now two seats available.
