Apparently Hamiltons new engine has been designed to run for less mileage but with much more performance, which explains his crazy speed.
Not sure if it's true but it would make sense, since some of his overtakes this weekend have been ridiculous, it looked like he was overtaking cars from F2 or another lower series, such was the speed difference.
Max should still win the title, but his refusal to give up a corner is going to cost him one day, for now FIA have allowed him to get away with it, but he is going to try it and a driver won't back out and he will suffer more crashes like he had at Silverstone.
Bottas is such a weird driver, looked decent in the sprint race but once again bottled the start and made it easy for Max to overtake him like he has done many times this season.
