Following the European Grand Prix on 21 May the teams conducted testing sessions across European circuits between 23–27 May to prepare for the Grand Prix. Jordan, Sauber, Benetton, Jaguar and Arrows opted to test at the Circuit Ricardo Tormo circuit which made its Formula One testing début that garnered mixed reviews from the drivers. Frentzen was fastest on the first day of testing, ahead of Sauber test driver Enrique Bernoldi. Jos Verstappen for the Arrows team set the second day's quickest times. Late in the session Fisichella hit the right rear tyre of Jordan driver Jarno Trulli, causing his Benetton to flip over and brought a brief halt to testing. Fisichella suffered minor bruising to his thumb and Benetton withdrew their second driver Alexander Wurz from testing. Sauber's Mika Salo topped the final days running. Williams and BAR went to the Circuit Paul Armagnac circuit which was where the teams undertook shake down runs and used car set-ups. BAR tested a new control system called "Athena 2000" which managed the software of the car's engine and different sections on the chassis. Ferrari tested at their private test facility, the Fiorano Circuit, for five days where test driver Luca Badoer and Michael Schumacher concentrated on aerodynamic and tyre testing, as well as undertaking different set-ups and running on an artificially wet track.
