Austin, Texas - Angry Australian Daniel Ricciardo left his mark on Sunday's US Grand Prix by punching through a wall in the Red Bull hospitality after suffering yet another engine failure.
The power cut-out happened while he was in fourth place, having seen off a challenge from Ferrari's Formula One title contender Sebastian Vettel.
"He's taken out his frustration in his room by putting his fist through the wall, which you can totally relate to," commented team boss Christian Horner.
"I'm sure he'll be having a word with his future employers about it - it's so frustrating to keep losing him from races at the moment."
Ricciardo is leaving Red Bull at the end of the season for Renault, which provides his current team with engines under Tag Heuer branding.
Horner said the failure was exactly the same one as Ricciardo suffered in Bahrain earlier in the year.
"It looks like a major issue in the energy store and it just takes out all the power," he said.
