The 1989 Hungarian Grand Prix was a Formula One motor race held at Hungaroring on 13 August 1989. It was the tenth race of the 1989 Formula One World Championship. The 77-lap race was won by Nigel Mansell, driving a Ferrari. After qualifying only 12th, Mansell charged through the field and took the lead with an opportunistic overtaking manoeuvre on Ayrton Senna in the McLaren-Honda as the two were lapping Stefan Johansson in the Onyx-Ford. Senna finished 26 seconds behind Mansell, with Thierry Boutsen third in a Williams-Renault. Senna's teammate and Drivers' Championship rival, Alain Prost, finished fourth, meaning that his lead over Senna in the championship was reduced to 14 points. Qualifying Pre-qualifying report The Hungaroring had been changed from the year before; the tight, slow S-bends after Turn 4 had been bypassed, extending the straight into Turns 5 and 6; raising the circuit's average speed by 10 percent. In the Friday morning pre-qualifying session, an Onyx topped the time sheets for the fourth Grand Prix in succession. Stefan Johansson was comfortably fastest, and his team-mate Bertrand Gachot also pre-qualified in fourth. Both drivers had re-signed with Onyx for 1990. For the first time this season, Piercarlo Ghinzani went through to the main qualifying sessions, in second place. For the third time this season, and for the first time since the US Grand Prix, he outpaced his Osella team-mate Nicola Larini, who missed out in fifth position. The Larrousse-Lola of Michele Alboreto was the other pre-qualifier in third, the Italian suffering from a cracked rib. His team-mate Philippe Alliot was down in sixth, the first time either he or a Larrousse had failed to pre-qualify. The AGS cars of Yannick Dalmas and Gabriele Tarquini were seventh and ninth respectively, while Zakspeed drivers Bernd Schneider and Aguri Suzuki, still hampered by their underpowered Yamaha engines, were eighth and twelfth. Roberto Moreno was tenth in the Coloni, while his team-mate Pierre-Henri Raphanel was unable to post a representative time and was bottom of the time sheets in his last appearance for the team. Gregor Foitek was still unable to pre-qualify the new EuroBrun car, and was eleventh fastest.
