Daniel Ricciardo's optimism turned to disappointment when he was forced to retire from the British GP with an electrical engine failure.
Ricciardo and his Red Bull Racing team have been dogged by various engine issues throughout this season and it was more of the same on Sunday.
Starting 10th the grid the Aussie had hoped for a good showing but instead found himself parking his RB11 on lap 22.
"I was really optimistic and excited for this weekend but it didn't work out for us on the day," he said. "We suffered an electrical problem which forced us to retire.
"I could feel the loss of power going into Turn 7, we tried circulating for a few laps to try and fix it, we also tried to reboot the engine in the pits but unfortunately it didn't work.
"The last few races haven't been kind to us but that's racing. We have some time off to look forward to and we'll go into Hungary a little more hopeful as the track there should suit us better."
As for Renault, the French manufacturer says they will investigate the cause of the failure.
"Daniel suffered an electrical issue during the race, which affected both the ERS-H and K," said Thierry Salvi.
"Despite several resets, we were not able to fix the issue on track and had to retire. The problem is under investigation and we will resolve it soon."
