Regardless, the Spanish driver got back on his feet by finishing P8 at the Saudi Arabian GP, scoring his first points of the season.Carlos Sainz reveals key factor behind his adjustment issue with WilliamsCarlos Sainz at F1 Grand Prix of Saudi Arabia - Source: GettySwitching from a race-winning team, Ferrari, to the mid-field outfit Williams has been a challenge for Carlos Sainz this year. Moreover, the power unit difference is apparently a key factor contributing to his adjustment issue.At Williams, he is using Mercedes' engines, whereas Ferrari have always had their own power units. Talking to Planet F1, he said,“The Mercedes PU is probably the biggest change in changing teams that I’ve had to adapt to. One is aerodynamics and suspension; you go through, and everything feels different. But when they change the engine, that’s when you really feel some big differences. I do feel very big differences compared to Ferrari.”Sainz also pointed out that Mercedes and Ferrari engines are poles apart, and the difference took him by surprise initially."It’s interesting, because it’s quite a big change, and it’s incredible how different two power units can be, but how close in performance they can be at the same time. I’m trying to give the team, and Mercedes, good feedback on what I believe Ferrari was doing better, and at the same time, giving feedback on what I think they are doing better than Ferrari," Carlos Sainz added.Sainz is likely to continue with Williams next year since he signed a multi-year deal. Moreover, the Grove-based squad has reportedly shifted their complete focus to 2026 to prepare for the impending onset of new engine regulations.
