Nigel Mansell once again suffered the curse of bad luck when a loose right rear wheel nut forced him to retire from the Hungarian Grand Prix in a commanding position. Having secured Williams' 25th pole position, Mansell led most of the race before being denied the victory when misfortune struck five laps from the chequered flag. Bitter rival and Williams team mate Nelson Piquet went on to take the win and, subsequently that year, the championship.
McLaren denied that Lewis Hamilton had used the 'F word' word as reported by British newspapers during a radio conversation with team boss Ron Dennis in qualifying for the Hungarian Grand Prix. Hamilton had been held up by team-mate Fernando Alonso during qualifying and missed the chance to complete a final flying lap. Papers later reported that Hamilton had had a heated discussion with Dennis, telling his team boss to 'never f****** do that to me again' and 'go f****** swivel.' On the same day, Malaysian driver Fairuz Fauzy returned to Formula One action to carry out a day of testing for the Spyker team. Fauzy, who had not driven the Spyker since May, assisted the team with their aero development programme.
Formula One commercial rights holder Bernie Ecclestone expressed his confidence that the United States Grand Prix would take place in 2006 despite question marks raised over the future of Indianapolis after the 2005 race was held without seven of the 10 Formula One teams when Michelin teams withdrew on tyre safety grounds. The fiasco was followed by harsh criticism of the event among the local public, subsequently leading Michelin to announce it would refund all ticket holders.
