Next year, in F1 there will be 21 rounds and the current 4 engine rule will be reduced to 3 with some element being reduced to 2.

Last race in Brazil, Hamilton had the new updated motor turned up in power, as it only needs to last two races and some estimate claim he had some 15 hp more than his team mate, this together with early pit stop during pace car to change tyre strategy to run the harder tyres when car was heavy (they can handle the extra weight better) and ran the super soft with the lift car at the end of the race, assisted in his great run from the pitlane to fourth position.

Hamilton comments on the new rules after his last race and I thing I must say I agree with him this time.
