Daniel Ricciardo says that Red Bull will need more time to improve the performance of their car ahead of the 2014 Formula 1 campaign, after a disappointing end to the second pre-season test in Bahrain.
The Australian mustered just 15 laps on the final day in Sakhir as his team spent much of the session behind screens trying to fix their ailing package, but Ricciardo tried to remain optimistic about the constructor's prospects.
He told reporters: "In all honesty it wasn't a great day today. I guess we still need more time. We have four more days coming up and hopefully we can maximise those.
"I have to say that on the run we did today the car did feel better. But unfortunately another problem arose and we couldn't exploit that potential.
"I hope we can do more running next week. I'm happy I'm doing the first two days. At this stage we just need laps and I'm just hanging to get back in the car."
Nico Rosberg posted the fastest time of the test in his Mercedes, 1.6 seconds clear of his nearest competitor, McLaren's Jenson Button.
