the Saturday morning practice sessions. Most of the teams fine-tuned the aerodynamics of their vehicles and used new and worn tyres at both the front and the rear. Ralf Schumacher had a new engine installed in his car due to oil pressure faults and extra downforce was added to his car which was substantially reconfigured. Häkkinen was fastest in the third practice session with a time of 1:19.115. Barrichello was second quickest, lapping 0.089 seconds slower than Häkkinen. Michael Schumacher was third fastest, ahead of Ralf Schumacher, Villeneuve, Jordan's Heinz-Harald Frentzen, Fisichella, Verstappen and Herbert in positions four to ten. Coulthard did not set a lap time during the session as his team changed his engine due to an malfunctioning electrical system. In the final practice session, a majority of competitors bettered their lap times. Coulthard had a trouble-free session and was fastest just after half way through the session with a time of 1:18.654, which was less than half a second slower than the record lap of the circuit set during qualifying for the . Michael Schumacher and Barrichello maintained their pace from Friday and were second and third fastest. Häkkinen was fourth quickest and was unable to lap faster as he passed an area with waved yellow flags. Trulli was fifth fastest, in front of Ralf Schumacher who was running quicker after set-up changes. Villeneuve, Frentzen, Salo and Fisichella followed in the top ten. Some drivers lost control of their cars during the session. Heidfeld's engine failed halfway through practice and dropped oil on the circuit, catching out Benetton driver Alexander Wurz. His Prost teammate Jean Alesi stopped on the grass when his car ran out of fuel. Pedro Diniz damaged the chassis and undertray of his Sauber car after mounting a kerb; he drove the spare C19 car for qualifying. Qualifying Saturday's afternoon one hour qualifying session saw each driver limited to twelve laps, with the grid order decided by their fastest laps. During this session, the 107% rule was in effect, which necessitated each driver set a time within 107 per cent of the quickest lap to qualify for the race. The session was held in dry and sunny weather; windy conditions were observed and there was a diminishing chance of rain. No driver appeared to venture onto the circuit that had been more dusty and slippery than in practice, particularly at turns eight and nine
