Lewis Hamilton is refusing to rule out a fight-back in Sunday's Chinese Grand Prix despite having to start the race from the back of the grid.
Hamilton went into Saturday's qualifying well aware that P6 on the grid was the best he could hope for given his penalty for a gearbox change.
However even that proved unobtainable.
The Mercedes driver's W07 suffered an ERS problem on his first lap out in Q1 and, although he ventured out for a second attempt after the red flag, he pitted without a time to his name.
Hamilton speaking to Sky Sports: "Of course it is unfortunate but these things are sent to try us and I am sure we will learn from it.
"I'm sure the guys are just as gutted as I am but we win and we lose together, so it’s really a case of trying to figure out the issue and make sure that it doesn’t happen again to either of our cars."
The last time he was forced to start from the back, the 2014 Hungarian Grand Prix, Hamilton raced to third place at the chequered flag.
This Sunday, he reckons it may be a bit more difficult given the tyre wear in Shanghai but he's not ruling it out.
"You can overtake here, the tyres don't last as well so it perhaps won't be as simple as it was in that race (Hungary 2014).
"The car is quick, hopefully they get the issue fixed and we can have a race tomorrow."
He added: "I'll give it everything I've got to try and get up. It isn't over until it's over."
