Hungarian Grand Prix winner Daniel Ricciardo says he won't completely rule out a title challenge for this year's Formula 1 World Championship until it is mathematically impossible to do so.

Following on from his maiden F1win in Canada last month, Ricciardo scored his second victory of the season in a thrilling Hungarian Grand Prix, consolidating his status as the closest challenger for the all-conquering Mercedes' of Nico Rosberg and Lewis Hamilton.

The only non-Mercedes driver to win a race in 2014, though Ricciardo admits it will be difficult to mount a title challenge against the superior Mercedes drivers, he is refusing to discount his chances until he is entirely ruled out of contention, particularly given the double points format of the Abu Dhabi finale.

"Until it's mathematically over it isn't," he said. "If you look at [Hungary], I closed in on the championship but realistically we're still a long way off. It doesn't really change the approach in any case. If we're in it or not, we still race for the highest position possible and obviously as we saw [at the Hungaroring], the win was there for grabs and we took it.

"In any case, I don't think it changes the approach for Sundays. I think with the Abu Dhabi system they've applied this year, it's still going to be pretty open until late on in the season. We'll just keep doing what we can."

Title aside, Ricciardo maintains it is important for him to keep pushing to the maximum all the way to the end of the season as the formerly dominant Red Bull Racing looks to recover ground in 2015.

"I think we're definitely going to keep trying to push for this year. There's still a lot to play for. In any case, what we learn this year we can still take forward for next year so the team will keep pushing and I'm sure that now this second victory will keep the motivation strong within the team so that's good."

"When maybe some of us say it's over, I think it's just purely looking at the performance of Mercedes. On a normal weekend with normal conditions on pretty much all circuits, they've been dominant. I think days like [Hungary], with some changing conditions, some safety cars, it helps us keep our nose in the fight."
