Looking for my second Yaris

[Kitt]

Hi!!

I am looking forward to purchase a new Yaris, I am still keeping my old one and I can say I pretty much know the car. However, I've been told that the fuel economy has decreased in the new model. In Panama we get the XP150 model (picture below), and several friends who have already purchased have told me this. It is the same engine (2nz-fe) but it looks like the rest of the car is heavier than the old version.

Can somebody tell me if this is true?
Does anyone owns it already?

This is the one I currently have


This is the one I am going to buy:
