Ferrari Formula 1 driver Sebastian Vettel will serve a second successive five-place grid penalty for a gearbox change at the British Grand Prix.
Vettel sustained a problem with the gearbox at the end of final practice at Silverstone, issuing a message over the radio in which he said: "OK, I think we failed the gearbox again."
Ferrari has changed the gearbox as a precaution, and is to investigate the matter next week, but it means Vettel will again drop five places for Sunday's race.
Prior to the Austrian Grand Prix a fortnight ago Ferrari had to change the gearbox on Friday as it discovered an issue it felt could have resulted in a failure.
Although no problems were encountered during the previous European Grand Prix in Azerbaijan, where Vettel finished second behind Mercedes' Nico Rosberg, an investigation of the car's systems found a potential issue.
