Before Sunday’s NASCAR Cup Series race at Circuit of The Americas, reigning champion Kyle Larson made a risky choice to keep his car on the starting grid despite unusual engine data detected during pre-race inspections. This decision came amid a challenging start to his season, with pressure mounting after poor finishes in the first two races.
Larson, driving for Hendrick Motorsports, began the season struggling, finishing outside the top 16 at the Daytona 500 and crashing out at Atlanta, leaving him 32nd in the standings. Early setbacks like these raised the stakes for the races ahead, including the COTA event where the engine issue added to the tension.
Pre-Race Engine Concerns and Strategic Decision
NASCAR reporter Jeff Gluck revealed that Larson’s engine showed abnormal readings when fired up Sunday morning. Teams typically must connect their cars to NASCAR’s official diagnostic tools before races, but doing so would have required Larson to start from the back of the field under NASCAR rules. After discussions with NASCAR officials on data access limitations, Larson’s team chose not to connect the diagnostic equipment, preserving their original starting position.
“The computer showed some abnormal readings related to Kyle Larson’s engine when it was fired up this morning. The team spoke to NASCAR about what data it could access. NASCAR’s rule is if they plug in, team goes to the rear. Ultimately, the team decided not to do that. They are heading to the grid and will start the race,” Gluck wrote on X.
By accepting the risk, Larson maintained his 15th place starting spot, behind teammate William Byron in 10th and Chase Elliott in fifth, while Alex Bowman began 16th. Despite the uncertain engine data, Larson proceeded with the race, hoping to build momentum.
Challenging Conditions Amid Strong Rivalry at COTA
Larson’s challenge at COTA was heightened by intense competition from Shane van Gisbergen, who dominated NASCAR road-course events last season. The New Zealand driver secured five wins in six road races in 2025 and already took the O’Reilly Auto Parts race victory at COTA earlier in the weekend. This made for a formidable rival as Larson struggled to find consistency on the track.
Larson’s history at the Austin circuit has been mixed. While he holds six career Cup road-course wins, his results at COTA have been less impressive, averaging finishes in the mid-20s and only once finishing better than 14th in five starts. His difficulties continued in the early stages of the race as he dropped toward the rear of the pack.
During Stage 1, Larson made a strategic call to pit on Lap 16, sacrificing track position to attempt a better long-run pace. This approach kept him in contention but limited his immediate gains, and he completed the first stage in 20th place, still searching for speed and stability.
Implications of Larson’s Decision and What Lies Ahead
Kyle Larson’s choice to avoid the rear-start penalty by not connecting to official diagnostic equipment highlighted a tense weighing of risks and rewards amid early-season struggles. This move allowed him to maintain his starting position but left uncertainty hanging over his race performance due to possible engine issues. With strong competitors like Shane van Gisbergen setting a high benchmark in road-course events, Larson faces a demanding path to regain momentum.
As the season progresses, Larson and Hendrick Motorsports will need to address both performance and reliability challenges quickly to remain contenders. The decisions made at COTA underline the pressure teams face in balancing technical compliance with race-day competitiveness, which can have a significant impact on championship hopes.
