racing debut at Austria, replacing the ill Eddie Irvine. Regulation changes To keep costs down, the V10 engine configuration was made fully mandatory in 2000 so that engine builders would not develop and experiment with other configurations but the V engine bank angle remained various. The V10 configuration had been the most popular since the banning of turbocharged engines in 1989, and no other configuration had been used since 1998. A change to red flag procedure was introduced, where races stopped after two laps but before three-quarters race distance had been completed would be restarted with the cars lining up on the grid in the order they were at the end of the penultimate lap before the lap during which the red flag was shown. Only the race order and number of laps completed were taken into account for the restarted race, with time differences between the cars voided; as such, the distance of the restarted race became the number of laps remaining from the original races, deducted by three. On 7 September, the FIA announced that using cooled fuel during a Grand Prix would be banned "with immediate effect". This was the last full season for cars competing without traction control, launch control, and fully-automatic gearboxes, until the and seasons, respectively. (Note: Traction control was reintroduced five races into the season, at the Spanish Grand Prix.) Season calendar {|class="wikitable" width=650px style="font-size: 85%;" |- ! Round ! Grand Prix !
