Red Bull has made a change to all four of its F1 cars for the Bahrain Grand Prix – across the main team and Racing Bulls.
Red Bull Racing has decided to switch out the power units in all four of its F1 cars, including the RB21s of Max Verstappen and Yuki Tsunoda, and the VCARB 02s of Liam Lawson and Isack Hadjar, before the Bahrain Grand Prix at the Sakhir International Circuit. The new components installed include energy stores (ES) and control electronics (CE). Each driver is permitted only two of each component for the entire season, with plans to possibly revert back to the original units later on. This change came earlier than expected, catching many by surprise, with no indications beforehand that the team would go through with these alterations. As of now, no other team has announced any power unit changes for the upcoming race, though Mercedes’ Kimi Antonelli faced a water pressure issue in FP1, potentially impacting the remainder of his season.
