the British Grand Prix, the Motor Sports Association was granted a reprieve by Formula One's governing body the Fédération Internationale de l'Automobile after promising to rectify the problems, and the next holding of the British Grand Prix was given a provisional date of 13 May 2001. After the French Grand Prix on 1 July the teams conducted testing sessions at various circuits across Europe between 3–6 July to prepare for the British Grand Prix. The Jordan, McLaren, Sauber, BAR and Jaguar teams tested at the Autodromo Nazionale Monza circuit. Heinz-Harald Frentzen set the fastest time on the first day, two-tenths of a second in front of Heidfeld. McLaren test driver Alexander Wurz recorded the fastest lap time on the second day. Irvine pulled out of the test sessions early because of reoccurring neck pains he had been suffering since June and was replaced by the team's test driver André Lotterer from the afternoon of the second day. Coulthard was quickest on the third day's running. Testing was suspended when Jordan test driver Ricardo Zonta spun off into a gravel trap after his car sustained a component failure and sustained heavy damage. Kimi Räikkönen for the Sauber team was fastest on the fourth and final day of testing. A crash by Häkkinen and a spin by Olivier Panis in the afternoon of the fourth day brought out the red-flags. Some teams made alterations to their cars in preparation for the race. Jaguar introduced a revised floor along with new bargeboards, whilst McLaren introduced minor aerodynamic revisions which included new front brake ducts. Sauber had brought new brake ducts and revised their bargeboards and Williams also brought new bargeboards for the race weekend. Prost reverted to an older undertray for Jean Alesi's car who preferred it over a new version débuted for the race. Practice Four practice sessions were held before the Sunday race, two each on Friday and Saturday. The Friday morning and afternoon sessions each lasted an hour. The third and final practice sessions were held on Saturday morning and lasted 45 minutes. Conditions were cloudy and blustery for the Friday practice sessions with heavy rain hitting the circuit before the day's running ended, preventing drivers from recording faster lap times. Michael Schumacher set the fastest lap of the first session after 45 minutes with a time of 1:23.619, almost eight-tenths of a second faster than teammate Barrichello in second.
