pre-season testing with West Surrey Racing, he got an invitation from Tauranac to join the works Ralt Formula Two team. Moreno finished runner-up to Mike Thackwell, the pair dominated the final European Formula Two Championship, in their Ralt-Hondas. He tasted victory at the Hockenheim and Donington Park races. Tauranac wanted Moreno to stay for the inaugural International Formula 3000 season (1985), but Moreno had been testing the Toleman at the end of 1984, with Senna's car. He look set to get a drive with the team, only to be told that they did not have any tyres, and the deal fell through. A move to Indycars was next for Roberto with Rick Galles's Galles Racing, as he had seen Moreno impress frequently. The deal was for Roberto to drive in the road race. He was invited to do a full campaign in 1986, however they had problems with the car and did not have any good results. When he was unable to find a full-time Indycar drive, he decided to try to get into F3000 driving with Ralt. During that season, he won Gran Premio del Mediterraneo, together with some consistent finishing saw him finished 3rd overall, before receiving the call to join up with AGS. Moreno almost joined the Brabham Formula One team in . On the suggestion of his friend, Brabham lead driver and defending World Champion Nelson Piquet, Brabham team owner Bernie Ecclestone almost signed the young Brazilian to drive the team's #2 car. However, this opportunity for Moreno came to nothing when Brabham's Italian based sponsor Parmalat insisted on having an Italian driver as Piquet's teammate. This led to the unique situation where Ecclestone signed brothers Teo and Corrado Fabi to share the drive in the car. Teo was the main driver, but as he was already contracted to race in the United States based CART/PPG World Series for Forsythe Racing, Corrado, who had driven for Osella in , substituted for him in 3 races where the respective F1 and CART schedules clashed. His performance at AGS did not get him a seat in F1. He went to Bromley Motorsport in F3000. The team, owned by Ron Salt, had Gary Anderson as its Technical Director, with whom Roberto had worked with at Galles. With help from Reynard Motorsport, they began the season with virtually no money. Revenge was sweet, when Moreno took a sponsorless Reynard-Cosworth 88D
