@ Khan45,
Many thanks for yor comment.
What happens is that when you come to a halt at a traffice signal or are stuck in a traffic jam, the entire power is shifted onto the battery and the motor which shuts off the engine and keeps the elctrical gadgets running such as the Aircon,Tv Nav and all.
As for the average per kilometer is concered, I delibrately wrote its as less then what it gives since some people on Palwheels have a problem of just giving a comment such as, no ways, I don't believe it, and God knows what else. You are right that it gives around 23-24kms per litre.
Regards
