What happened: Mercedes-AMG F1 used social media to mark the start of Monaco Grand Prix race week, telling followers it hardly needs reminding that the sport's most storied weekend has arrived. The post was a promotional buildup to the running on the Monte Carlo street circuit rather than a competitive update.

Why it matters: Monaco remains Formula 1's most prestigious event, where the narrow, barrier-lined street circuit puts a premium on qualifying position and offers few chances to overtake. Because clean-air track position is so hard to recover on Sunday, a strong Saturday is frequently decisive to the final result.

What to watch: Attention turns to practice and qualifying, where grid position on the tight Monte Carlo layout typically shapes how the race unfolds.
