Mark Webber has called Red Bull car troubles "stupid" and "embarrassing" after another KERS failure hampered his efforts in qualifying in Hungary.
Not for the first time this season the Aussie was forced to qualify without KERS after an electrical issue stopped the system for working.
Giving his all in a seriously hampered car, Webber made it into the final shoot-out where he opted not to run.
"KERS, gearbox, you name it... driving the car so far off the potential is unbelievable and so massively frustrating," Autosport quotes him as having said in the wake of qualifying.
"It's stupid, it's embarrassing and it's a brutal circuit to be out of position.
"We should be challenging for the front row and we're bloody 10th. So, a pain in the arse.
"It's amazing... all the effort you go to and it's two weekends on the bounce where you get that."
And even though there are two DRS zones at the Hungaroring, Webber fears he may struggle to make up ground especially if the car's issues continue.
"The team have got to get the car operating at the limit tomorrow. It's a long race and things need to be functioning correctly.
"KERS was 50 per cent [of the problem] and there were other things.
"So we managed to tick nearly every bloody box in qualifying and made it hard.
"Hopefully we'll get that sorted for tomorrow, but it's going to be hard to get the result we should do."
