Red Bull could be back in the championship battle as soon as Spain, when the team is planning a chassis revamp.

Whilst many expected the new, aero focused regulations to work in Red Bull’s favour, the team has been far behind Mercedes and Ferrari so far this season. With Daniel Ricciardo saying the chassis should be stronger, it’s clear that it’s not only the weak Renault engine to blame.

“We are working day and night to pick up our shortcomings,” Helmut Marko told

“We are pretty optimistic that we will make a significant step forward in Barcelona, where a big change of parts is coming.

“The chassis will be ‘revamped in Barcelona and Renault is planning something for Montreal.”

The RB13 may look radically different in Barcelona, but team principal Christian Horner says the team still believes in the potential of the different philosophy.

“I think the philosophy that we have pursued and adopted is slightly different to the competitors and we still believe in the potential of that,” he told Autosport.

“I don’t think we have managed to extract the performance that we believe the car is capable of yet, and the development path should allow to open up.”

At the moment, the team is taking it “a race at a time”, but Horner is hopeful it will enjoy a better half of the season.

So far, Red Bull has taken a single podium positon in three races. Red Bull may still be third in the constructors’ championship, but they have less than half the number of points as Mercedes in second.
