Highcroft's Simon Pagenaud and David Brabham took their HPD to its third straight victory in the American Le Mans Series at Miller Motorsports Park, but had to work hard to defeat the Drayson and Intersport teams.
It was Intersport's Jon Field who took full advantage of his LMP1-based Lola-AER's power to burst from fifth to first at the start, while the LMP2-derived Highcroft HPD was shuffled back to sixth.
Drayson driver Jonny Cocker took the fight to Intersport in the opening laps and made it into the lead near the half-hour mark. Meanwhile Highcroft was picking its way slowly forward, and when the leaders all pitted under yellow after an hour, Pagenaud's crew got him out fastest and into the lead. He would lose that advantage again to the two Lolas during the next stint, but then ran eight laps farther than his main rivals before making his final pit stop half an hour from the end.
That was enough to vault Pagenaud back into the lead, 15sec ahead of Cocker's teammate Emanuele Pirro, and he inched slightly farther away before clinching the win and bolstering his and Brabham's points lead still further.
With the Dyson Lola-Mazda stopping on track in the last half-hour and Intersport losing time when Field made contact with the Green Earth Gunnar LMPC car, the CytoSport Porsche emerged in third.
Risi Ferrari dominated in GT with Jaime Melo and Gianmaria Bruni, who were only briefly headed when the No. 92 Rahal Letterman BMW decided to stay out as the other lead GT cars all pitted under an early yellow.
That strategy helped the No. 92 crew to second, ahead of the No. 3 Corvette, which fought back after a late penalty for running over its air hose. Its sister car stopped on track just two laps into the race and required long repairs.
Two punctures cost erstwhile GT points leader Flying Lizard Porsche, which fell to fifth in class ahead of the Giancarlo Fisichella/Toni Vilander Risi Ferrari, which was hampered by a back of the grid start after failing a ride height test, and later by a penalty for avoidable contact.
Victories in the one-make classes went to Level 5's Christophe Bouchut and Scott Tucker in LMPC and Black Swan Racing's Jeroen Bleekemolen and Tim Pappas in GTC.
