Red Bull had high hopes for its RB13 ahead of the season, having been promised considerable progress from its power unit supplier Renault. The team had build extremely agile chassis in 2015 and 2016, but soon realised that the RB13 would be another beast. As early as pre-season testing, it was clear that the car was no match to the field leading Mercedes and Ferrari cars.
The problems triggered several team members to openly attribute their difficulties to correlation issues with the wind tunnel. Certainly not an oversight from a very experienced design team, but the radical chassis regulation changes did make it more difficult to very data without on-track running. It caught Red Bull out, admitting they had underestimated the aerodynamic impact caused by the by the overall increase in the width of the cars - up from 1800mm to 2000mm - and the increase in tyre width - up from 245mm to 305mm and 325mm to 405mm, at the front and rear respectively.
On top of that, the team was also taken by surprise by a technical directive issued by the FIA during the winter. The document effectively banned some specific advanced suspension designs following a clarification request made by Ferrari. It was understood at the time that Red Bull were indeed chasing such a suspension design, in particular to help control heave and roll of the car to improve its aerodynamic performance.
The inability to control the car's behaviour as much as they wanted to, resulted in a car that was much less effective than its predecessors - at least compared to the team's rivals. It is believes that these setbacks during the winter resulted in the team tracking back on advanced aerodynamic control structures, leading to a car that in the first races was extremely straightforward and clean, featuring much less small bits and pieces than other cars.
At the first European race, the Spanish GP at Barcelona, Red Bull fitted its RB13 with a raft of aerodynamic upgrades, the first major step after having to resolve the wind tunnel calibration issues behind the scenes. According to some senior figures, the issues had caused the team roughly two months of development time. As of that moment, updates kept on coming, and the car clearly got closer to the leading Mercedes and Ferrari cars. It enabled Daniel Ricciardo to score 5 subsequent podium finishes, including a win at the Azerbaijan Grand Prix.
However, Spa-Francorchamps brought Max Verstappen's 6th power unit related retirement of the season, and increased tensions between the team and its engine supplier. The more upgrades Red Bull put into its car, the more efficient the chassis became, but the more obvious it was that on top end power, the team still had a considerable problem that would prevent it from fighting at the front, especially at power sensitive tracks.
