Reutemann's relationship with his teammate soured when, the following season, Reutemann disobeyed the team's orders and thereby refused to allow Jones to win the 1981 Brazilian Grand Prix. Jones never forgave this act of disobedience on the part of his teammate, while Reutemann felt frustrated at Jones' refusal to acknowledge his help, especially after having just given him the victory at the 1981 USA West Grand Prix. Reutemann continued to score more points than Jones throughout the remainder of the season, and the Brazilian victory (and another in Belgium) helped put him in a position to challenge for the title in a three-way battle with Nelson Piquet and Jacques Laffite at the season-ending race in Las Vegas. In what was probably a defining moment of the season, Reutemann was ordered at the 1981 Germany Grand Prix to turn over his unit to teammate Jones for the race due to the latter's car failure and had to race with the third unit of the team. That proved disastrous when his engine failed, preventing him from scoring points in a race where he had qualified in 3rd place.
