Spanish GP rule change leaves Lewis Hamilton clueless as F1 rivals all say same thing

Formula 1 drivers do not believe the rule changes coming into force at this weekend's will have a dramatic impact on the balance of power on the grid. That's despite earlier hopes up and down the grid that it might curb the performance advantage that has been enjoyed by .

concurred, the driver adding: "I wouldn't expect more than a one tenth [of a second] swing up or down through the field for each team, depending on how much you were flexing or not. I don't think there's going to be a lot in it."

And , who would love to see McLaren hampered as he hunts a fifth-straight F1 drivers' title with , said: "I think all of the teams will be a little bit impacted, probably some more than others, but it's not going to change the ."

As for Ferrari racer , the Brit was not even willing to offer a guess. He said: "I have no idea. Honestly, I have no idea what the directive is going to do. I couldn't guess. I've just been training and trying to get ready for this weekend, nothing special."
