I doesn't have a better fuel consumption and it's less powerful than a normal 2.0 engine, obviously slower. What is the purpose of this? Why does it exist?

I think the fuel consumption number can be misleading. If you had this versus regular 2.0 and did the same route around city with lots of stop-start traffic, this hybrid would save some fuel, I am sure.
But is it worth it and does it make sense? In my opinion - no. There is a thing called "Diesel engine" which burns oil-like fuels and converts fuel into mechanical motion with less waste heat. Mazda should try that.

Yes, indeed. Even otto engines can run biofuels, maybe with some small changes.
But almost everywhere you get petrol or diesel at pumps anyway.
So if you still want to make a not powerful hybrid, why not choose a smaller and less thirsty engine like everyone else does? It just doesn't make any sense. It's a bit funny really :)
