Sauber not blaming engine partner Ferrari for slump

Sauber has faith in engine partner Ferrari despite the unit lacking in power when compared to the superior Mercedes unit, according to team principal Monisha Kaltenborn.

The Swiss team is struggling to find its feet in 2014 and has yet to score a point in the opening 11 races. That equates to its worst ever start to a season and Kaltenborn says the power unit is one of the problems holding them back.

"It is one of the major factors, but I don't think it is as easy as saying it is somebody else's fault," she told the official F1 website.

"We always have to look at ourselves first and, being very honest about it, this car is definitely not one of the better cars that we've built. This has its reasons and we know them."

Kaltenborn refuses to put the blame solely on Ferrari though - unlike Red Bull and Renault - and doesn't believe it would be constructive to do so especially when they've been partners for so long.

"We have a very long lasting partnership with Ferrari and in all these years we've gone through good and not such good times, but you stick together and get through it.

"I am not really aware of the situation between Renault and Red Bull, but ours with Ferrari is a close and very open relationship. We've never done that [point the finger]."

The Indian has confidence in Ferrari's ability to turn things round.

"I am very sure that if I am unhappy and dissatisfied, then my colleagues at Ferrari have double that amount of frustration, so I don't need to worry about that. The important thing is that they see the road ahead and know what to do, and I have full trust and confidence that we will get out of this slump."
