Red Bull managed only three laps on the third day of testing as further problems struck the RB10 at Jerez.
After Sebastian Vettel
completed a total of 11 laps on the opening two days of the test, Daniel Ricciardo fared little better on Thursday after he stopped on track on his installation lap and only managed two further laps before running was ended for the day. While Wednesday's issue was described as a Renault
energy store problem – with all three Renault-powered teams doing little running – Thursday saw the team blame its early lack of track time on a car-related issue, suggesting that the latest Red Bull
problem is specific to the RB10.
Race engineering co-ordinator Andy Damerum said it was in the team's best interests to take a cautious approach at such an early stage of testing.
“We worked hard yesterday to make the changes it was felt were necessary to overcome the problems we identified and we were hopeful of a more successful day today,” Damerum said. “Unfortunately, the measures we took only partially solved the issue and, as with yesterday, it's more sensible to stop and dig deeper into finding a solution.
“It's obviously not where we want to be and naturally the whole team is frustrated by these issues. However, we're pretty good at bouncing back from this type of thing. This is where the whole team pulls together and I'm sure we will get these problems fixed.”
With Red Bull
having completed 14 laps in total only Marussia (2) has a lower tally for the week having first run the MR03 on Thursday afternoon.
