Between my wife and I we have a 2010 Auris Hybrid and 2010 Prius (all Prius are Hybrid). I got the Auris Hyb first, I wanted a Prius but couldnt justify to myself the difference in price between them. They are both the same Hybrid system, so if you like the way the Auris drives you should like how the Prius drives - thats referring to the Hybrid bits ie engine and battery system. The suspension may feel different, as may the steering.
I liked driving the Auris Hyb, but I got the chance in feb this year to buy a private sale Prius at a good price. I jumped at it, sold the wifes Yaris diesel and gave her the Auris. I prefer to drive the Prius, dont know why, but I am more at home with it then the Auris Hyb. Both are T-Spirit models, which is supposedly top of the range but the Auris has part leather seats, electric foldable door mirrors, and auto lights - but non of these on the Prius.Whilst the Prius has a 7" screen with maps the Auris does not. Strange but thats how it is.
I believe their was a Prius facelift in 2014, dont know what that included. Being longer you get more boot space in the Prius and more footroom for the rear passengers.
If you happy with the Auris Hyb I can imagine you being happy with a Prius. Let us know how you get on.
