Gazoo Racing AE86 Hydrogen and EV concepts

The AE86 has a combined mileage of 31mpg, so that would give us 115 miles (186 kilometres) range. The latest Nissan Leaf has a range of 149 miles, so at least it's not much worse than that!

Also keep in mind that the Mirai gets double the range per kg of hydrogen (60-80% efficiency with fuelcells vs <30% with an ICE) and has a small battery for recuperation. Hydrogen in a combustion engine is more of a gimmick than useful in any way.
Also, it's obvious why they didn't go sideways, running on hydrogen with minor changes means it loses about half the power. Try going sideways with some 60PS @ 5000rpm peak power.

In terms of keeping these old cars on the road in the future, I only see either EV-swapping them or getting gasoline/diesel-equivalent E-fuels. Those are approaching some 4-5€/liter (pre-tax) and could possibly be sold with lower tax than fossil fuels (politics allowing...). With further improvements in the power-to-gas processes it's reasonably possible to reach 2€/liter production costs. They'll never beat EVs in efficiency or cost/kilometer (energy, maintenance, etc), but they'd be cheap enough to run for keeping a healthy oldtimer community afloat.
