Radio messages in full: Rosberg and engineer on his gearbox issue
Nico Rosberg was handed a 10s penalty by stewards following radio instructions given before his second-place finish in the British Grand Prix at Silverstone, dropping him from second to third.
Rosberg hit trouble with six laps to go, after his Mercedes appeared to lose seventh gear.
This is the transcription of what was said between Rosberg and his engineer Tony Ross.
Rosberg: “Gearbox problem.”
Engineer: “Driver default 1-0-1, chassis default 0-1, chassis default 0-1.”
Engineer: “Avoid seventh gear, Nico, avoid seventh gear.”
Rosberg: “What does that mean, I have to shift through it?”
Engineer: “Affirm Nico, you need to shift through it. Affirm, you need to shift through it.”
What are the rules?
Such advice appears to be in breach of F1's team radio restrictions, which dictate that drivers are only supposed to receive instructions when a car-stopping problem is imminent.
As Motorsport.com revealed earlier this week, the FIA had told teams ahead of the Silverstone weekend that it was getting tougher on what they could tell drivers.
It was made clear that any breaches of the regulations would be reported to the stewards for potential punishment.
Rosberg finished just over a second ahead of Red Bull's Max Verstappen, so his 10s time penalty dropped him to third. Fourth-placed Daniel Ricciardo was a further 20s back.
The gap between him and Lewis Hamilton has now closed to one point.
