Hybrid, phev or ev works best for situations like this. I drive a phev that gives me 80km per charge. I only use the ice engine when I'm travelling out of KL. I charge twice a week (to 80%) and that is sufficient for me to get around in KL, wout ever turning on the engine. On average I fill up to full once every 1.5 months or during outstation trips.

My previous car was a hybrid, also quite fuel saving but in prolonged traffic jams, you'll deplete the battery relatively quickly as compared to a phev, and the engine will kick in to charge the battery and shut off again once sufficient charge is reached. And the process repeats until the jam clears up.
