the Grand Prix. The characteristics of the Hungaroring circuit requires teams to run their cars with a high load of aerodynamics and attention was placed onto dissipating heat since high temperatures were recorded at the circuit. McLaren introduced a revised aerodynamic for their MP4/15 chassis, aimed at increasing the amount of downforce, and therefore grip, produced by the bodywork. They also brought revised nose wings. McLaren also strengthened the car's steel rear suspension wishbones. BAR fitted their cars with one-off components that were produced to help optimise the performance of the monocoque's cooling systems. Ferrari introduced an aerodynamic setup similar to that used at the , and the team debuted a modified version of the F1-2000's chimneys. Minardi arrived with new radiator intakes and exits to rectify temperature issues with their Fondmetal V10 engines. Practice There were four practice sessions that were held before the Sunday race—two one-hour sessions on Friday, and two 45-minute sessions on Saturday. The Friday practice sessions took place in dry and hot weather conditions; track temperature lowered later on when clouds covered the circuit but ambient temperature remained consistent throughout. Nearly 20 minutes passed before any lap times were set as 15 drivers completed out-laps to allow them to conduct systems checks. The track was dirty due to a lack of activity for several months and race organisers were unable to completely clean the circuit. Michael Schumacher waited for other drivers to clean the dirty track and set the first session's fastest time on his first quick lap, at 1 minute and 20.198 seconds, in the final moments of the session. He was almost six-tenths of a second faster than teammate Barrichello. Jaguar's Eddie Irvine was third fastest, ahead of Williams' Ralf Schumacher. Fisichella, BAR driver Jacques Villeneuve, Jordan's Jarno Trulli, Diniz, Mika Salo of Sauber and Williams' Jenson Button completed the top ten. The two McLaren set no lap times during the session, opting to conserve their tyre usage. The session saw several teams focused on testing the high downforce aerodynamic packages fitted to their cars. In the second practice session, Coulthard set the day's quickest lap of 1:18.792 with approximately 15 minutes of the session left; The time was half a second slower than teammate Häkkinen's pole lap at the 1999 Grand Prix. Häkkinen was second fastest. The two Ferrari drivers were third and fourth—Michael Schumacher ahead of Barrichello. Trulli was running quicker
