Press the D3 button on the gear leaver to get more power. There's a very big differnce.. But of course it consumes more fuel.. In the i-mid it says that it does 5km/l.. At times it says 4,4.5.. So far it has gone only upto 6km/l in my one.. But I think it does more than that.. What does your i-mid say?
I've been using it for a month now.. Superb machine I would say..
