The topic pretty much says it all. Can some technically sound folks share their knowledge regarding the optimum rpm for the Vario during city driving? My impression was that the lower the RPM, the better the mileage (i.e. less fuel consumed), but I've recently been told that that might not be true.
I get around 12 km/litre within the city with 100% AC on my 2007 Vario. Would like some feedback on what other people's experiences are like.
