Sebastien Bourdais (#01 Ganassi Cadillac) took lead at the start of the second hour, passing opening-hour pacesetter Ricky Taylor (#10 Wayne Taylor Racing with Andretti Acura) with ease into Turn 1.
Taylor then fell back behind Felipe Nasr's #7 Penske Porsche 963, as it paid the penalty of its short energy fill and double-stint on tyres.

The #6 Penske Porsche 963 of Tandy charged up from last in GTP to fourth, but gave up that spot to Richard Westbrook in the customer JDC-Miller Motorsports 963. Westbrook then passed poleman Pipo Derani (Action Express Caddy) for third.
Dixon (in for Bourdais) and Cameron (in for Felipe Nasr) battled for the lead after second round of pitstops, which was interrupted at the end of the second hour when Steven Thomas crashed heavily at the exit of the Bus Stop chicane in the #11 TDS Racing LMP2 entry.
At the restart, Louis Deletraz led the way in the #40 WTRA Acura thanks to some pit strategy – running some 25% less energy than the chasing pack – heading Dixon, Aitken (in for Derani) and Cameron.
Deletraz though was forced to pit before his opposition, handing the lead to Dixon, who was 3s clear of the second Cadillac of Aitken. Penske Porsches ran third and fourth after three hours, with Gianmaria Bruni fifth in the Proton-run customer 963 and the first of the BMWs driven by Nick Yelloly in sixth.
