What happened: Mercedes featured Kimi Antonelli in a cap-stacking challenge with the team's orange Austin special-edition headwear during pre-race promotion in Texas. The paddock stop follows Antonelli detailing his race-week rituals and pranks before Austin.

Why it matters: Formula 1 teams regularly roll out venue-specific merchandise for the United States Grand Prix to meet commercial demand in the Texas market. Special-edition Austin headwear and #12 driver gear anchor Mercedes' stateside fan engagement across race week.

What to watch: On-track sessions for the MSC Cruises United States Grand Prix get underway this weekend at Circuit of the Americas.
