Hartmann preps for IRA Labor Day weekend tripleheader
(PEDAL DOWN PROMOTIONS) August 27, 2025 - After 23 days out of the driver's seat, Austin Hartmann and the members of the 87A Hartmann Racing Team got back at it last week with the NOS Energy Drink World of Outlaws and Bumper to Bumper Interstate Racing Association. On Tuesday, Aug. 19, Hartmann and crew traveled to far western Wisconsin to take on the World of Outlaws 410 Sprint Car Series at Mississippi Thunder Speedway in Fountain City, Wis. The fifth-year Sprint Car competitor qualified 23rd in the 27-car field with a lap of 12.045 around the lightning-fast, third-mile high-banked clay oval. After placing seventh in the second heat race, the Plymouth, Wis. driver advanced to the 30-lap A-main with a second place showing in the Last Chance Showdown. Hartmann held strong in the main event to post a 21st place showing. The team made its first-ever visit to the LaSalle Speedway in LaSalle, Ill., with the Bumper to Bumper Interstate Racing Association on Saturday, Aug. 23. The 2020 Plymouth Dirt Track Racing and Midwest Sprint Car Association 360 Sprint Car Rookie of the Year Award recipient qualified 19th overall in the 36-car field with a lap of 11.679 seconds on the quarter-mile high-banked dirt oval. He then placed sixth in the first IRA heat race before starting fifth in the B Main. Hartmann was running seventh, needing to place in the top four to advance to the main event, when an incident on lap 8 ended his evening early. He was credited with a 10th place showing. "It was another IRA show where the results weren't what we wanted," Hartmann said. "I didn't have a very good night behind the wheel. We're looking forward to getting things straight for the three-race weekend coming up." 87A Hartmann Racing Team is preparing for a big tripleheader weekend of IRA action starting at The Plymouth Dirt Track in Plymouth, Wis., for the annual Sheboygan County Fair race on Friday, Aug. 29. The following night, Hartmann joins the IRA for the Harry Neitzel Tribute and Jim Wipperfurth Memorial in what is being billed as the final Sprint Car race at Beaver Dam Raceway in Beaver Dam, Wis., on Saturday, Aug. 30. Spectator gates are scheduled to open at 4 p.m. with racing starting at 6 p.m. The weekend closes with a return visit to The Hill Raceway in Sturgeon Bay, Wis., with the IRA 410 Sprint Car Series.
