I have the FWD 2023. It's under 10k used.. gives 9-10kmpl on normal Petrol with AC.. if you push the engine, easily comes down to 8kmpl.. haven't seen it do 12 kmpl so far even on long drives on motorway etc. AWD is even 1-2kmpl behind in these figures.
I've heard good things about the alpha.. would love to hear other experiences
