Armstrong loses XPEL Grand Prix at Road America
Marcus Armstrong was forced to abandon a championship‑level performance in the XPEL Grand Prix when a sudden mechanical issue caused the 25‑year‑old to retire with four laps left, handing the victory to Arrow McLaren’s Christian Lundgaard.
55‑lap, 4‑mile chaos shakes the field
The adverse weekend unfolded over a 4.014‑mile, 14‑turn natural‑terrain circuit that saw five cautions ripple through the running order, with drivers deploying a mix of pit‑strategy gambits that constantly reshuffled positions.
Lead battle culminates in last‑lap heart‑breaker
Starting third, Armstrong steered the #66 Meyer Shank Racing Honda from second place to a 2.5‑second margin ahead of Lundgaard in the final quarter of the race, only to see that advantage evaporate when his car began to slow four laps from the finish.
Final caution forces out‑of‑track exit
As the engine sputtered near the exit of the 14‑turn corner, smoke erupted and prompted the flagman to call a caution. Armstrong was forced to leave the track, and with no repairs possible, the team retired the vehicle, clearing the way for Lundgaard to embrace the championship‑important win.
Armstrong’s on‑track remarks and team pride remain sincere
When FOX Sports asked why the failure had gone unnoticed, Armstrong said, “No, it was all smooth sailing… the engine started spluttering, but it wasn’t out of fuel… the engine completely died.” He added that he did not receive any warning from the dashboard or the engineers.
Despite the 24th‑place finish, the New Zealander praised the crew: “I’m massively proud of the and the team; the fastest car, spot‑on pit stops, everything right. We had a good pocket, but it was gut‑ting.”
Final sprint sees Lundgaard fend off Malukas
A one‑lap shoot‑out followed, with Lundgaard holding off Team Penske’s David Malukas, sealing the win for Arrow McLaren in a race defined by late‑stage drama, rapid pace changes, and the unanticipated breakdown of a contender.
