the Italian Grand Prix. Marques moved into a reserve/test role for the rest of the season. Luciano Burti suffered serious injuries during a crash in the Belgian GP. He was forced to sit out the rest of the 2001 season and was replaced by Czech driver Tomáš Enge for the remaining races. Changes Rule changes The eleven teams and members of Formula One's governing body, the Fédération Internationale de l'Automobile (FIA) held a meeting on 30 August at Heathrow Airport to discuss rule changes for the 2001 season. It was agreed that drivers would be allowed to use an extra three sets of tyres during Friday's two practice sessions. Ten days later at Monza, team bosses accepted to ban in-season testing during the month of August and a three-week break would be implemented during that time period. Safety car For this season, Mercedes-Benz provided a new safety car in the shape of the SL55 AMG, which also performed this duty during 2002 and replaced the previous CL55 AMG. It was first deployed during the German Grand Prix. Season calendar {|class="wikitable" width=650px style="font-size: 85%;" |- ! Round ! Grand Prix ! Circuit !
