Lucas Luhr captured his 22nd pole in P1 qualifying, running a lap of two minutes, 7.851 seconds (95.736 mph) in the No. 6 Pickett Racing Muscle Milk HPD ARX-03c. He and co-driver Klaus Graf – who have already wrapped up the P1 championship – will be seeking their sixth consecutive victory in Saturday’s two-hour, 45-minute race.
Luhr was joined by Marino Franchitti and Renger van der Zande in winning pole positions for the prototype classes for the race, Round 7 of 10 on the 2013 schedule.
The changing conditions proved a challenge for Luhr, whose team did not participate in the optional testing earlier in the week.
“There was no constant rain, so the track was getting drier and drier,” Luhr said. “Then when the track dried out, it got very greasy and you ended up overheating the tires.”
Chris McMurry qualified second in the No. 16 Dyson Racing Mazda/Thetford/Norcold Lola B12/60, 2:12.837 (92.143 mph). Third in the class was Andy Meyrick, in the debut of the No. 0 DeltaWing DWC13 coupe with Katherine Legge, 2:15.845 (90.103 mph).
With his team fastest overall in both days of unofficial testing, Marino Franchitti continued the momentum for Level 5 Motorsports, taking his third pole of the season and seventh straight this season for the team with a lap of 2:10.573 (93.741 mph) in the No. 552 Siemens/Alpine Watches/Ohiya Casino Resort HPD ARX-03b.
Franchitti was also challenged by the changing conditions.
“You needed the wet tire, because it wasn’t dry enough for slicks,” Franchitti said. “But the wets were wearing down pretty quickly, and I was just hanging on.”
Extreme Speed Motorsports’ Johannes van Overbeek and Anthony Lazzaro took the next two positions in P2, with Level 5 Motorsports’ Ryan Briscoe losing his right-rear wheel at the beginning of the session and failing to post a qualifying time.
Van der Zande captured his first ALMS pole in Prototype Challenge presented by Continental Tire (PC) qualifying, turning a lap of 2:17.865 (88.783 mph) in the No. 81 DragonSpeed dress-for-less.com ORECA FLM09.
“We knew we had a very fast car in the wet,” van der Zande said. “But in the end the track started drying and a lot of people started getting close, so we kept pushing.”
Ryan Dalziel took second with a lap of 2.18.929 (88.103 mph) in the No. 5 Starworks Popow Motorsport entry, followed by Kyle Marcelli in the No. 8 BAR1 Motorsports ORECA, 2:19.782 (87.565 mph).
