Webber upbeat about 'evolutionary' car

Red Bull have been cautious not to tinker with a successful formula but Mark Webber
is confident of another competitive season after a shakedown run in his F1
challenger.
The RB6 - described by the team as a design "evolution" - does not radically depart
from the car which gave Webber and teammate Sebastian Vettel six victories last
year.
"To be honest we finished last season with a first and a second so we didn't want to
go to great lengths to design another car on the back of that or go too crazy,"
Webber said.
"I think there are a lot of subtle, small things that will hopefully make this car
more successful than last year's."
Apart from small aerodynamic changes the car, like its rivals, is longer to
accommodate a larger fuel tank since refuelling during a race is banned this season.
Webber ran a leisurely ninth out of 10 cars during the test session but was hampered
by a wet track and an oil leak that led to a precautionary engine change.
But he was impressed by the machine he hopes will extend his grand prix record of
two wins, both achieved last season.
"It was a pretty positive feeling actually," he said.
"It wasn't exactly a clean day of testing with the changeable conditions but that is
the same with everyone.
"We haven't done the track time that we should have, but in the end we still got 50
laps on the car.
"Everything felt as we targeted and expected. On a normal wet, slippery day at Jerez
it felt fine. There were no real vices in the car.
"We still have to understand a few things with it, but now it is shaken down we can
start to do a bit of work tomorrow."
He said the lap times, led by Mercedes driver Nico Rosberg, were deceptive and the
team could not establish the pace of the car properly.
"It's impossible because you've got people out there who are one minute flying and
the next minute not flying, so it's hard to say who is doing what."
Red Bull designer Adrian Newey described the new car as a "sensible evolution" of
the 2009 car with the double diffuser the big difference.
"We tried to refine and evolve it rather than go to new concepts," Newey said.
"The two main challenges were the larger fuel tank and the smaller front tyre."
Vettel, runner-up to Jenson Button in last year's world championship, said the
team's decision to skip last week's opening session at Valencia would not be a
disadvantage but they needed to optimise the remaining testing time.
"Most important now is that the car is running and that we improve the reliability
and speed," Vettel said.
"First you need to make your car work, then you see where you are and according to
that you set your expectations."
