Vettel unsure of Red Bull challenge in 2015
10 July 2014 – Sebastian Vettel is unsure if Red Bull will be able to recover sufficiently to challenge Mercedes in 2015.
The Milton Keynes-based outfit has struggled for performance and reliability so far this season, with power unit supplier Renault encountering a host of problems in the early stages of Formula 1's new turbocharged V6 era.
When asked if he feels his team can bounce back and draw level with the Silver Arrows next year, Vettel responded: "It's difficult to say, right now the gap is very big and we didn't really close it since the first race.
"We have tried lots of things to improve but they do the same thing. We need bigger steps of development to close the gap even more. I think at the end of the season we can judge a bit better what to do in the winter."
With a poor start and misjudged strategy hindering his chances at the British Grand Prix, the reigning World Champion has set his sights on returning to the podium at his home event in Germany next weekend.
"It has been a little bit up and down this year," he said. "We hope for a smooth weekend without any problems.
"I will try and get the best out of myself and the car. It would be very special to finish on the podium there."
Vettel currently lies sixth in the standings, three places and 28 points behind team-mate Daniel Ricciardo.
