Red Bull endured another disastrous day in Jerez as Daniel Ricciardo ran only three laps, and he failed to record a time before the team confirmed that it would not run again today.
On his first outing this morning he stopped on track with smoke rising from the rear of the car. The team is continuing to work with Renault to address packaging issues.
Adrian Newey and Christian Horner were spotted leaving the track.
Race Engineering Co-ordinator Andy Damerum said: “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. 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.”

Enstone’s decision to not attend this test session looks like genius now. Save the money and let the other Renault teams get the obvious bugs out of the powertrain.
