What happened: During the sprint at the Singapore Grand Prix, Kimi Antonelli received an unexpected message over the Mercedes team radio. Teammate George Russell briefly took over the communications channel, playfully introducing himself to Antonelli as his new engineer, "Giorgio."

Why it matters: The interaction provided a brief moment of levity amidst the demanding conditions at the Marina Bay Street Circuit. It also offered a glimpse into the relaxed dynamic between the two drivers, even as Mercedes puts Russell on an older specification for a split test.

What to watch: The team will continue to gather data from both cars throughout the remainder of the Singapore Grand Prix weekend.
