2.0 dti or 2.2 dti?

Hello to each other! Come from the Vectra A-Forum, but I also like the Omega very, very well. As much as I have noticed, there are two different diesel engines at the B-Facelift: the 2.0 16V DTI and the 2.2 DTI. Personally, I tend to the 2.0, because it has less hp and is therefore cheaper in Austria in the insurance. My questions: – What about the acceleration (can you compare the one of a Seat Alhambra with 110 HP TDI engine)? – Dur cut consumption to 100km? – Does the 2.0 DTI have a control chain or a timing belt? – What advantages/disadvantages does the engine have? Thanks already in advance! Greetings, Florian PS. another question: Does the Omega Caravan Elegance have a 12V socket in the trunk??
