SILVERSTONE, England (Reuters) - Daniel Ricciardo's run of five successive podium places looks in danger of ending after the gearbox on his car was replaced ahead of the British Grand Prix, incurring an automatic five-place grid penalty.
Gearboxes must last for six races and the one in Ricciardo's Red Bull, which was swapped out before Saturday's final practice, had not done so.
