Audi Q3 Sportback 40 TFSI Quattro

I'm just about to deal on one of these in a Black Ed spec for my parents, they're coming out of a 2014 Q3 2.0 TDI S Line which they've had from brand new.

Does anyone how good or bad these are on fuel?

Also I don't know whether it's in my head but the Sportback is about 3/4cm lower than a regular Q3 so don't know if anyone regrets buying one in favour of a regular one - I appreciate thats all personal opinion though.


Any thoughts?
