Feb.20 (GMM) Red Bull's early-season crisis has raced from Jerez into Bahrain, as the second of just three pre-season tests began in the island Kingdom.
"Obviously we're not happy with where we are now and we have a long way ahead of us," said world champion Sebastian Vettel, after completing just 14 laps in the troubled Renault-powered RB10 on Wednesday.
The German warned that the problems - different to the overheating and Renault-related issues that almost completely wrote off the Jerez test - will not have "a quick fix".
"Very often you fix one problem and another pops up, which is what happened," said Vettel.
Team figures Adrian Newey and Dr Helmut Marko admitted recently that the main Red Bull problem at Jerez was overheating.
And that also seemed a problem in Bahrain, with Guardian correspondent Paul Weaver reporting an obvious "smell of scorching" from the Red Bull garage.
Vettel was even seen snatching a fire extinguisher from a hesitant marshal after breaking down on track.
"Our guys are getting very little sleep right now - one to three hours maximum," the 26-year-old driver told reporters.
Vettel said it would be wrong to "separate" Red Bull's problems from troubled partner Renault's, and there were concerned faces all round when Renault president Jean-Michel Jalinier met on Wednesday with Marko and Christian Horner.
On a different note, the German is still opposed to the new 'double points' innovation.
"This is nonsense, and punishes those who have worked hard for the rest of the season," he said at the time.
But those comments were made before Red Bull and Renault struck serious technical trouble with the team's new RB10 car.
As the crisis entered a second test week in Bahrain, German Vettel was asked on Wednesday if he is now suddenly supportive of double points, given he might eventually need a boost to catch the runaway 2014 title leaders.
"I think it's February, yes the season starts in four weeks, but I think that's not fair, that's a bit too harsh," Vettel answered.
"No matter which way I'm not a big fan of the double points because I don't understand the reason for it, but yeah, I hope that up to that point we have had lots of good races," he added.
