Reigning world champion Sebastian Vettel insists that Red Bull remains in the hunt for the championship, despite Mercedes's dominant start to the 2014 season.
Mercedes has won all six races from pole position in 2014, leaving their rivals to fight for the scraps.
Vettel, who has scored just one podium finish this year, retired from last weekend's Monaco Grand Prix and is now 77 points behind championship leader Nico Rosberg.
"Mathematically we are right in there," Vettel told reporters at a promotional event for next month's Austrian Grand Prix.
"We are looking at the situation race-by-race. Of course it did not go well recently but we are looking forward to the next races.
"For sure we made progress and this proves we are on the right path. We won't be favourites in the near future, but over a race distance, anything can happen. There are always reasons for setbacks, and I do not believe in bad luck. We just have to sort the problems out."
Vettel also distanced himself from rumours linking him with a move away from Red Bull.
"I'm fascinated that journalists react so quickly," he said. "It is not long ago that Red Bull had some very successful years. Now we have had six races and we are not so successful and there are already discussions about my future.
"We are still the second force in Formula One, ahead of Ferrari for example, so it could be worse."
