Brought into the little team for financial reasons, Londoño took part in the special acclimatisation practice session held before the Grand Prix weekend. This session was held because the Jacarepaguá circuit had not been used in F1 for some time. He performed reasonably well in the session, but it became irrelevant when the FIA elected not to grant Londoño the necessary licence to take part in the proper practice sessions and the race, due to his lack of experience. Ensign replaced him with Marc Surer, who qualified for the race and finished 4th, amazingly putting in the fastest lap of the race.
Even though he did not take part in the official practice sessions, he was entered for the race, so Londoño is officially Colombia's first Formula One driver. He retired in 1985.
