Mercedes boss Toto Wolff has revealed that the cause of Rosberg’s slow pit stop was due to a simple stopwatch failure.
After Rosberg was handed a five-second time penalty as a result of running Max Verstappen off the track when he made a move on the inside of the Turn 6 hairpin, he was forced to serve his penalty during his next pit stop.
However, rather than serving five seconds, Rosberg ended up serving eight when the stopwatch used to time the penalty failed.
“It was a stopwatch failure, the time thing failed. It didn’t function like it should have,” Wolff said.
“We could have also counted, one thousand and one, one thousand and two, one thousand and three but we relied on the stopwatch and it let us down.
“Even in a Formula One team with all the high-tech, if you get to take out the instruments that you usually don’t use like a stopwatch, they can fail.
“The stopwatch didn’t start properly and once we realised we had to take it safe and this is why it took longer than normal.”
