I know you are all thinking F1 going two stroke is a joke, but forget about the oil burning strokers of the past that we all love (well I do anyway!). The 2 strokes that are being looked in to are ultra modern with hydrogen and carbon extracted from the air combined with synthetic eco fuels.

Symonds says that even by retaining combustion engines, F1 could still capture the 'green crown' in coming seasons with its focus on synthetic eco-fuels that combine carbon harvested from the air with hydrogen.

There are some amazingly clever people in F1 who have the resources to develop such technology. Just look what they've achieved with the 4 stroke engine.
I've always believed that the future is with hydrogen. Now if F1 can make it a proper reality, that to me is pretty exciting stuff as I just dont buy all this battery powered car crap as it's just not as eco friendly as we're all lead to believe due to some of the reasons in the post above plus many more.
If F1 do go down the road of 2 strokes with all the modern and future tech I recon we could have some ultra powerful small capacity engines that are super clean and sound awesome which would bring some of the magic back to F1 as well as paving the way for the future of transportation.
