Come on! A lot of changes this year and last year comes from Aerodynamic side. I can NOT understand why FIA still believe that the frozen engine costs a lot of money? I thought all developments is on aero side.
Mercedes, Ferrari and Toyota are all protesting because it makes no sense for automakers to use some STANDARD engine and promote themselves.
I am always a fan of F1 because it is promotes technical innovation for racing. I don't really care about the environment or going green. You have the solar race for that. Like Ferrari, I will definitely quit watching F1 if they want to make every car identical.

53% of the vote in F1technical says it all.
