Well technically Mexico is not telling either because there is such a thick layer of sweeping gravel at the top and the event is run so high up that so theoretically any engine power advantage would be mostly gone.
Corsica is a twisty tarmac rally where we will see who has a good tarmac chassis but not much else, Argentina will again mean sweeping and possibly problems with splitters and water splashes... Etc etc.
The simple truth is that you have to be strong at everything as a team - car - driver combo to win the championship.
Only time will tell who that might be, but it is a lot closer this year.
Neuville has the speed and the road condition to win in Mexico for sure. Fun season to come! :)
