The rest of 1989 was characterised by gearbox and various other problems, including a disqualification at the Canadian Grand Prix and a black-flagged incident at the Portuguese Grand Prix for reversing in the pit lane, which resulted in a ban for the next race in Spain. However, Mansell finished fourth in the Championship with the help of a second win for Ferrari at the tight and twisty Hungaroring for the Hungarian Grand Prix. Early in practice Mansell had seen that trying to qualify the car high on the grid was a pointless exercise and he decided instead to concentrate on a good race set-up. After qualifying 12th (0.681s behind teammate Gerhard Berger in sixth and 2.225s behind pole man Riccardo Patrese in his Williams-Renault) and not even being considered a chance for the race, he charged his way through the field until he pulled off a sensational passing manoeuvre on the McLaren-Honda of World Champion Ayrton Senna on lap 58 to take a lead he would not lose.
