don’t forget about the massive turbo
and anyway, if F1 looks like it’s trying to be environmentally conscious it means less trouble from the green party and others of the like. More car manufacturers are starting to use 4 cylinder turbos because of their efficiency. We may even see more manufacturers joining f1 again.
More power will come in time, I think, but I don’t think it will be big high revving engines. More power will come in the form of more electric technology.
