Sauber 'pretty confident' issues identified in – the first time the team has failed to get at least one car to the checkered flag since Monza in 2011. It also marked the first time the squad has failed to score in at least one of the opening two races since 2010.
Sauber struggled at the start of 2013 too, and while things did improve, it wasn’t until the second half of the season that they really turned it around.
“I hope it doesn’t take that long [this year] as we are pretty confident that we have identified where the issues are – hopefully," Kaltenborn told the official F1 site prior to this weekend's Bahrain Grand Prix, the third round in the 2014 Formula 1 World Championship.
“Melbourne was important because we finished with both cars and Kuala Lumpur a disappointment because we thought that we’d developed in the right direction," she added. “It was not meant to be. Nevertheless we will follow our route, as we believe in the end we will be successful.
“Now we will have to go through the data to see what the cause of our struggle was. We certainly have to do things on the chassis side, and we also have to see to the powertrain side. We have to work on both sides," she concluded.
