Isack Hadjar, Arvid Lindblad, and Franco Colapinto have been hit with grid penalties ahead of the Bahrain Grand Prix at Sepang due to exceeding the allowed number of power unit components. In Formula 1, each driver is permitted a set number of components, such as the internal combustion engine, turbocharger, and exhaust system, per season. Hadjar will use a seventh internal combustion engine this season, which means he will start the race from a lower position on the grid than he would have otherwise. Lindblad, driving for the Racing Bulls team, has exceeded the limits for multiple components. His car is equipped with a fifth internal combustion engine, along with a fifth turbocharger and a fifth exhaust system, all of which are beyond the allowed limit of four units. This accumulation of penalties exceeds the 15-place threshold, meaning Lindblad will automatically start at the back of the grid, regardless of his performance in qualifying. Colapinto, driving for Alpine, is facing two separate penalties. One comes from installing a new engine, and the other is from a previous incident during the Azerbaijan Grand Prix, where he collided with his teammate Pierre Gasly, causing a chain reaction that also involved Lando Norris. The stewards imposed a ten-second penalty on Colapinto, which was converted into a five-position drop in the starting grid for the next race. Now, he must combine this penalty with the new one related to his power unit, which will further affect his starting position. The weekend presents additional challenges for teams as Formula 1 returns to Sepang for the first time in eight years. Teams are also dealing with extreme heat and a lack of recent data on how current cars perform on the Malaysian track. Hadjar started the weekend on a positive note by posting the third fastest time in the first practice sessions, behind Max Verstappen and George Russell. However, his penalty means that even a strong performance on Saturday may not secure him a favorable starting position for the race.
