I took a test drive of a Maruti Versa, and the car is pretty 'cool', both in terms of its looks and handling and in terms of its AC. Now I am only upset about one fact that it runs on petrol and gives only about 9-10kmpl (probably with AC on). I want to know if the car AC can be set up to draw power from a car battery and not from the engine.

Any tips, suggestions, insights or links?
