Red Bull chief designer Rob Marshall says he is confident that the reigning world champions will be able to unlock the potential of the RB10 with the initial focus being on improving the Renault power unit.
Red Bull endured a challenging pre-season testing campaign but has shown potential during the races, with Sebastian Vettel collecting a podium finish in Malaysia.
The team is currently in fourth place in the constructors' championship and Marshall insists that, despite Red Bull's pre-season form, they was not surprised by competing for the top three positions in Australia.
"It was pleasant, but not too much of a surprise," he said. "We struggled a lot in pre-season with reliability issues. You suffer because the parts you need to fix a problem take time to make. You design the fix, wait a while to get the part and then try it again."
"There are many more bits and so many ways of putting things together incorrectly that the job takes a very long time – but we've already improved significantly."
Marshall says that the RB10 is responding as Red Bull expects but that the team needs to get the car - and power unit - optimised.
"It appears to be behaving to expectations – but we're just scratching the surface with what it's capable of," he said.
"We still need to get the car optimised in its current form. Then there's continued aero development and a lot of work in unlocking what the engine's capable of.
"We'll be attacking all of that, but in the short term the obvious thing to is to get the engine really performing."
