do formula one cars refuel during the race
Formula One regulations From 2010, refuelling is no longer permitted during the race: every car starts with a full fuel load. The 2010 season cars were about 22Â cm longer than 2009 cars to accommodate the enlarged fuel tank this necessitated.
Safety car The first use of a safety car in Formula One is reported to have taken place at the 1973 Canadian Grand Prix, where a yellow Porsche 914[5][6] was called for duty following various incidents under treacherous weather conditions. Controversially, on that occasion, it took several hours after the race to figure out the winner and final results since the safety car driver had placed his car in front of the wrong competitor thus causing part of the field to be one lap down incorrectly.[7]
