had used in the first five races of the 2002 championship. The team installed a new aerodynamic package that included a revised undertray, front wing and altered bodywork around the cover of the C21's engine. The Ferrari, McLaren and Williams teams brought new front brake air intakes. Williams also used an upgraded front wing on its FW24, which was characterised by a curved profile. Practice There were four practice sessions preceding Sunday's race, two one-hour sessions on Friday and two 45-minute sessions on Saturday. The first practice session was held in cool and overcast weather. Michael Schumacher was fastest with a lap of 1 minute, 11.072 seconds with approximately ten minutes remaining. His teammate Barrichello, Felipe Massa and Nick Heidfeld of Sauber, Jordan drivers Giancarlo Fisichella and Takuma Sato, Coulthard, Arrows' Heinz-Harald Frentzen, and the British American Racing (BAR) duo of Jacques Villeneuve and Olivier Panis, were second through tenth. Some drivers—including Barrichello, Massa and Fisichella—ran off the dusty, slippery track into a gravel trap during the session because of a low amount of grip; none sustained damage to their vehicles. Conditions became warmer and sunnier for the second practice session though rainfall threatened towards the end. The fastest times were recorded within the first 20 minutes since the track temperature was at its warmest. Barrichello set the day's fastest lap, at 1 minute, 10.549 seconds. His teammate Michael Schumacher was three-hundredths of a second slower in second position. Montoya, Kimi Räikkönen of the McLaren team, Allan McNish for Toyota, Arrows driver Enrique Bernoldi, Jaguar's Pedro de la Rosa, Panis, Coulthard and Sato were third to tenth. Some drivers, including Michael and Ralf Schumacher, and McNish, again lost control of their cars and ran off to the side of the track during the session. Heidfeld's track time was curtailed after 20 minutes due to an alternator fault. Frentzen lost a quarter of an hour to familiarise himself with the track after he spun over a kerb and damaged his car's undertray. The third practice session took place in clear and dry weather; no drivers ventured off the less slippery circuit. Michael Schumacher used low track and ambient temperatures to become the first driver to go below 70 seconds all weekend with a lap of 1 minute, 9.001 seconds that he recorded half an hour in. His teammate Barrichello was second-fastest and Räikkönen third. Frentzen, Massa, Coulthard, Heidfeld, Panis, Button and
