Replace... nah, F1 will gravitate closer to that system but stop short of full electrification.Formula e is a concept that will replace F1. People don't believe it will happen but i think it will. The cars will spin around road courses in a gentle buzz sound like a Radio Car.
Electric is the wrong way to go and the industry knows it, it's wasteful and harmful to the environment, just like diesel it's a stopgap until the world can make Hydrogen economically feasible, in the meantime Vettel's "race without a trace" should provide will provide noise without nonsense.
All we need is the bean counters and the tree huggers to agree on the way forward, and I'll say it again... it ain't electric.
