Piquet took the team's last wins: two in 1984 by winning the seventh and eighth races of that season, the Canadian Grand Prix and the Detroit Grand Prix, and one in 1985 by winning the French Grand Prix. He finished fifth in 1984 and a mere eighth in 1985 in the respective Drivers' Championships. After seven years and two world championships, Piquet felt he was worth more than Ecclestone's salary offer for 1986, and reluctantly left for the Williams team at the end of the season.
