KERS is still optional.
Le coeur a ses raisons que la raison ne connaît point. 
As far as I know - KERS is mandatory for all teams. The Red Bull car has KERS on it. But for some reason the drivers are under orders not to use it. I think it has something to do with a secret design in their car. I wonder if the button works?
