Yeti 1.2TSI Cool Edition Luggage compartment vs. wheelchair or dog box

Hello together, at the moment a Passat Variant Bj 2011. I discovered today og. Yeti with daily registration for 17900 Euro (200 km, no four wheel) Since we have to transport again and again in change either a wheelchair or a medium sized dog box, asks me the question whether the YETI is suitable. Has anyone had experience in this regard? Friday I have the appointment to test and estimate the passat at the friendly dealer where I also bought the passat. I’d like to know how to drive in winter with snow. The box shape of the Yeti might not be as fast as the passat, would it? I’m happy about the answers 🙂
