"Audi plans to produce its last internal combustion car in 2033", that part is anymore, because the first page that posted it and a lot of them don't say that, and possibly they will also adapt the H2-ICE (hydrogen internal combustion engine) with low NOx and with more efficiency, i hope an ecological world without harm people's taste and environment.

Sounds great, oil from cooking fuels, then you read also from plants. There's no percentage breakdown of the split but I'd expect very little of it to come from chip fat so all the claim does it make it sound green, just how green is cutting down forests in the amazon to grow fuel crops.
