The spirit of this market is to see if by 2050, all Formula 1 contenders have removed Internal Combustion Engines (ICE) from their car.
It would not require a rule, but it would require that all contenders are free from ICE.

Hydrogen Fuelcell -> Resolves positive

@Odoacre There already is a formula-e, so I'd be suprised if they took this route.
If they changed their name, but they were clearly the same entity and didn't fork into different organisations, I would resolve as if it was still named Formula-1.
If they disband, and formula-e becomes the dominant race, I will resolve ambigious.
