However, he mentioned that the car didn't agree with Verstappen's driving behavior. The Dutchman particularly struggled in the slower corners of the Bahrain International Circuit.During pre-season testing, it was revealed that Red Bull were running their cars much lower than others. However, when asked about whether the issues in Max Verstappen's car were due to the FIA forcing the team to raise their car, Helmut Marko denied it and clarified that this was not the case.Junaid #JB17@JunaidSamodien_There was a lot of experimentation with the front axle and apparently the ground clearance was also increased.

In the first session, the two-time world champion struggled with the balance of the car and eventually finished third, behind Fernando Alonso and his own teammate, Sergio Perez. Furthermore, he continued to have difficulty connecting with the car in the second practice as well. Speaking to on-site media, including Sportskeeda, he explained:“FP1 was really bad, just couldn’t get a balance which was odd because in testing whatever we tried, maybe somethings were maybe not that amazing, but not that far out, so few things to understand. Even the start of FP2 was a bit difficult but even at the final run even though we were not really having a good reference and confidence up until then with the car- the lap was not too bad in the short run and also the car, we got a bit more connected."Oracle Red Bull Racing@redbullracingA busy day ‍ Time to debrief 4776220A busy day 😮‍💨 Time to debrief 💬 https://t.co/wNscCveANRLater on, Max Verstappen managed to find his rhythm with the RB19 and was quite pleased with its pace:"Then in the long run, I think with all the changes that we made, I was quite surprised with the pace we had.
