Aussie driver Daniel Ricciardo has revealed that while the power unit in his Red Bull Racing contender has produced an extra tenth of a second a lap since the season opening Australian Grand Prix, the engine won't receive a major upgrade until the Canadian Grand Prix a little later in the year.

The Red Bull racing team have shown flashes of speed and have attempted to take the fight to Mercedes and Ferrari and the hope is that a revised version pf the RB13 that we will see in Barcelona will be ‘a bit of a bullet' and hopefully propel them into the battle for podium finishes.

Daniel, I want to start with a technical question. You struggled with tyre temperature in Bahrain, with track temperatures not expected to be that high here, are you worried that the issue will be the same at this grand prix?
Not worried. I think we learned a bit from that. We had the test on Tuesday after the race. We experimented with a few things, so I don't expect to be in that position again. So yeah, we'll see. We know that this track is one where you sometimes circulate for a bit and then do a push lap. The tyres maybe aren't' there on that first lap for, say, qualifying but I think for the race we should be OK. We'll be alright.

The team is planning to bring pretty much a new car to the Spanish Grand Prix in a couple of weeks' time. What do you expect from that car – and what are the major problems with the current car that need addressing?
I expect… I'll use the word hope, not expect. I hope for a bit of a bullet: something fast. We want to be in a three-way fight with Ferrari and Mercedes. So, that's what I would hope for: something that puts us in that fight. I look back at least year and think here in qualifying we were over 1.5s off pole and then we went to Barcelona and we were about half a second off pole and we made some gains and then obviously in Monaco we were quick. It's a time of the year where we should start to see these updates take place and some performance really start to come out of the car. I'm hopeful of that. We just need a bit of everything now. We've talked a bit about downforce, feeling a bit in the rear. We've had a bit of time to look at Ferrari: they've been in front of us for a few races and can study them for a lap or two before they get too far away and yeah, they look strong. Mercedes as well: they're just carrying a bit more grip in the rear and that's where all the lap time is in these cars these days.

You say you want a bullet – but the guys next to you aren't standing still. Are you confident the upgrade in Spain is going to be enough to make it a three-way fight at the front?
I hope so. I'm confident it's going to be better than what we've got now and for now that's all we can ask for is an improvement. A bit like last year: we made that step and were able to just keep chipping away at it. I think to make that first step is important. I believe we will get that in Barcelona and then let's see where it puts us. If it puts us within half a second, then I think we're in striking territory soon after that.

The latest information from the FIA says that the cockpit shield has received the nod over the halo for 2018. First of all, which of the two systems do you prefer, what do you think of the shield in any event?
Yep. Like Kimi said, we got a presentation in China, I think, all us drivers, about the new shield. I think yeah, we've still got to see a bit more but yeah, first impressions seem OK and I guess we'll now try and get some development on that and then start to run it in some practices as soon as they can put it on the cars and then get some more feedback on it. It's good that they're still obviously looking for this head protection stuff so that's positive.

Which is your favourite track?
Favourite track? To drive on: Monaco. Yeah. It's unique. It's so tight and twisty and the whole weekend is great as a spectacle but for pure driving and as far as adrenalin goes that's a stand-out above the rest.

Daniel, your lack of performance, if I can call it that, is it all on your car or is there something missing in the driver and if yes, what is it?
No, nothing's missing in the driver. I haven't forgotten anything. I think just with the car – we know that we can do better, I guess. I think we'll see that in Barcelona. I think the team's learned a lot from the past, from testing but also the past few races and also with our feedback, myself and Max's feedback, I think we've been targeting the same things and I think now the team has really understood the point on the car to work on, to focus on and that's why now they're bringing this update for Barcelona and that's as soon as it can come. That's pretty much that, so for everyone asking why isn't it here for this weekend... it takes time to build the parts, basically, and then to put them on the car. They test them and then it takes time for the development and all the process but  from Barcelona we should be good. From a driving point of view I feel good, very good.

What is the main feature of Sochi for you?
Yeah, I think the low grip makes it quite tricky, quite unique and a lot of the corners are flat so there's not really any camber, any positive banking to kind of pull you round the corners so when it's slippery and you have like a flat corner then it's a lot more easy to slide and it's harder to sometimes find the grip so that's a challenge but quite a fun one. There's not many tracks we go to now with that feature and yeah, as Pascal said, I guess it's turn 13 I believe, after the back straight, braking for there is quite tricky. That's a good one, it can be a passing opportunity as well. If you can pull off a move  there it's normally a nice one.

Daniel, you said about the development of the car; what about the power unit? Is there a development from Renault, from Australia to now?
Yup, power unit  - we've had a little bit since Australia, so it hasn't been an upgrade but we've been able to squeeze a tenth out of it since then, I would say, and I think around Montreal we're looking for let's say that power unit upgrade where we should hopefully find a couple of tenths or something like that. Yeah, we're obviously still trying to get chassis and power unit stronger but yeah, the big upgrade has not come yet.
