It was another quiet race on the team radios in Bahrain which again suggested the restrictions on what information teams can pass onto their drivers is having a significant effect.

That was certainly a concern for Marcus Ericsson, who wasn’t sure whether his team could tell him if the information he was getting from his dash display was correct.

During the race there were occasional bursts of activity on the radios followed by long silences. A spate of messages around laps ten and eleven were followed by fourteen consecutive laps of silence.

It’s doubtful nothing was broadcast during this time – one message from Rosberg during the race indicated he was receiving updates most laps. Formula One Management may simply have chosen not to broadcast any or could have been experiencing technical problems. Certainly many of the messages broadcast during last year’s race would remain legal under the new rules.

A lot of the team’s post-race discussions were broadcast, included a revealing message from Romain Grosjean after his combative drive to fifth place. Complimented on the quality of his overtaking moves during the race the ex-Lotus racer replied “well I’ve got brakes this year, that helps!”
