editAt the start of the race at turn 1, Vautier and Pla had a collision that led to Pla needing to pit during the next lap of the race. In addition to this, both Milner and Serra both got tire punctures and also needed to pit. Around twenty minutes into the race, Saavedra spun around the final corner and was hit by Montecalvo who was flipped over following a hit to the tirewall.[33]Just before the four hour mark, an awning blew onto the track bringing out the yellow flag. Almost immediately after the caution ended however, Brundle spun during the final turn.[34]
