Back-to-back qualifying sessions at the Coates Hire Ipswich 400 have produced very different front rows for this afternoon's two 100km V8 Supercars races, with the field separated by under a second in each run.
With Craig Lowndes sitting at the top of the times for the majority of the first session, Red Bull found momentum at its home test track, with Jamie Whincup to line up alongside his teammate for today's first 100km race.
Scott McLaughlin and his Volvo came home third, with Holden's Fabian Coulthard, James Courtney, Erebus' Will Davison, Ford's Championship leader Mark Winterbottom, David Reynolds, Shane van Gisbergen and Chaz Mostert completing the top 10.
Others to note include Todd and Rick Kelly in 12 and 13 for Nissan, Garth Tander 15, and Jason Bright 17.
Red Bull tweaked Whincup's car between sessions, with team principal Mark Dutton saying there were "no concerns, just the usual tuneups between sessions. He wasn't quickest - so when you're not quickest you have to tune the car up."
However, Whincup and Lowndes would be relegated to the second row this time, with McLaughlin scoring his fifth ARMOR ALL Pole Position for the season, and a surprise result for Nissan's Michael Caruso, starting on the front row alongside his good Kiwi mate.
"Extremely pleased to be on the front row particularly at this circuit given our normal struggles," Caruso said.
"Great for Norton and Nissan. The guys on the 36 car have done a great job. We continue to progress forward and that's pretty encouraging."
After the Red Bulls, it was van Gisbergen, Rick Kelly, Mostert, Nick Percat, Tim Slade and Coulthard.
Winterbottom won't be happy in 11th, to start alongside Townsville race winner Garth Tander.
Others to note include Courtney 13, Bright 14, Davison 15 and Reynolds 19.
Race 23 will begin at 2.25pm AEST, with Race 24 to start at 4.30pm at the Coates Hire Ipswich 400.
