The former champions have admitted that the current performance deficit is due to both the chassis and Renault engine.
So at Milton Keynes, Red Bull is busily working on what is said to be a ‘B’ spec chassis, set to debut in Barcelona in a fortnight.
“I think the top teams with more resources can obviously improve the most,” said Ferrari’s Sebastian Vettel ahead of the first European race of the season.
There are rumours of a 1 second per lap boost for the new Red Bull in the simulator, but Ricciardo said he isn’t getting excited.
“I think I’ll believe it when I’m driving it,” said the Australian.
Indeed, it seems likely that the Spanish grand prix – and even the Montreal event two races later – will not be the silver bullet for Red Bull.
Germany’s Sport Bild reports that a scheduled big upgrade for the Renault power unit will now not be ready for Canada, for reliability reasons.
The report said the debut has been postponed “indefinitely”.
Red Bull investigating ‘very strange’ troubles
Team boss Christian Horner said the team would investigate Ricciardo’s problem and early indications suggested it was a different issue to Verstappen’s at Sakhir.
“It’s similar outcome but different issue so we need to understand the cause of it,” Horner told reporters after the race. We’ve got a bunch of bits at the moment so there needs to be a full investigation as to what caused the issue.
“Was it a touch at the second turn, was it something else, because after the restart immediately the component has failed. Everything before seemed under control so it was absolute sudden failure.
“It’s just very strange to happen immediately after the restart.”
Ricciardo added: “It was early in the race so I don’t know how much the safety car and two starts impacted us but the team will obviously investigate that.
“It’s frustrating, on a Sunday you just build up for the race and try to store up your adrenaline to use at 3pm but today it was over very quickly.”
