Red Bull team principal Christian Horner insists that the team are making steady progress with their 2015 car.
The former champions have had a torrid start to the season due to problems with their Renault power unit, but Horner believes that they have moved forward since the Australian Grand Prix.
He told reporters: "We're definitely making progress with the car; Bahrain was actually our most competitive weekend.
"The problem we've got is that we're running in such a compromised state, so we're not in an optimum window with the car.
"Our straight-line speeds are down and then you end up trimming wing out to try and get something sensible. And that hampers other things such as tyre warm-up and downforce.
"So we're not in a window with the car where we want to be at the moment, but certainly we've made significant progress."
Daniel Ricciardo finished sixth in Bahrain, while his Russian team-mate, Daniil Kvyat, finished ninth.
