Team Penske’s Scott McLaughlin led Thursday morning’s 2h30m high-boost session at the Indy Open Test, posting a best lap of 232.686mph in the No. 3 Chevy with the benefit of the draft.

The best and most session-relevant lap, which came with no aerodynamic tow, belonged to Rahal Letterman Lanigan Racing’s Takuma S ato, who produced a 232.565mph lap in the No. 75 Honda. McLaughlin’s top no-tow lap was a 230.020mph, good enough for fifth on the no-tow list.
