Citroen C4 PureTech 130 (EZ 2023) Technical questions

Hello dear ones, I am unfortunately not a car expert and asked my colleague for help, who is quite familiar with cars. Since I am totally interested in the current C4 petrol tank (2021-2023), he wanted to know the following. And since I am not so well-versed and do not know where to research, perhaps one of you can answer the following questions: Does the C4 have a belt in oil running or a control chain? Which automatic gearbox does the C4 have? And which engine is the hand Is it possible? 1 litre? 2 litres? I’m talking specifically about the Citroen C4 PureTech 130. I’m sorry if you could actually do a super easy research. But maybe you can help me.
