Formula 1 team Red Bull unveiled their new car for next season - the RB9. After three championships in a row won by Sebastian Vettel, Christian Horner's team are looking to make history and gain a fourth. Only Michael Schumacher and Juan Manual Fangio have won four titles in a row, if he makes it he will be the youngest ever to do so.
But the man responsible for the domination, design genius Adrian Newey, admitted it was getting harder and harder to keep their edge at the head of the field.
Last year’s title race went to the final round and it took a miracle for lucky Vettel to wrap up the championship by just three points.
"It is increasingly difficult because there are no real regulations changes compared to this year and it will be the fifth season since the 2009 rule changes," Newey said.
"The devil has very much been in the detail with this car. We've tidied up some bits that we felt could be improved on. Development is now the key through the year."
"The field is converging and you can see how competitive it is in the fact that we had eight different winners last year."
The new car will be debuted by Mark Webber at the first test in Jerez, Spain on Tuesday.
