lets assume that
MB has 600 HP
Ferrari 550 hp
Renault 520 hp
Honda 500HP
What if for the incoming 2 years (16/17)
engines are artificialy restricted by the FIA ( air intake rings for example)
and the regulated outputs are
MB 550
Fe 530
re 520 no restrictor
Honda 500 no restrictor
Engines shall be tested by FIA and they will equailize
during those 2 years manufactures will do the catch up and afer that free again
those that have advantage will keep it but no so big as today
