Does anyone have clue on the energy consumed with say a 2010 ish passat.

The newer cars are fairly sensitive to the voltage of the battery, I do not think that they would be happy with a dropping voltage.

One could install a super capacitor bank instead of the battery, and then charge that with regulated voltage from a different energy source. This would have the benefit of keeping your car at its happiest voltage and you can use several different types of batteries in parallel. With very minor changes in voltage one could use one set of batteries and once those go low, you could switch to other sources of batteries.

On the plus side with a newer car, the power gains are more significant.
