I agree with UncleO- short distances between lights, start stop mode and many speed bumps esp in housing estates here in Singapore really do take their toll on mpg.
In largely city driving I get 16-17 km/l...if I have a high mix of expressway driving I get close to 19.
As far as EV mode goes...maybe it is my inexperience, but so far it has been
difficult to find and even more so
to hold. I do get it very rarely and it requires VERY light pressure on the gas pedal. Even with the foot pressure changes caused by road surface bumps I seem to lose the EV mode...
or maybe I should try driving barefoot?:-) which is actually suggested by one hypermiler guru...
Anyway, if you have not seen this please see

Also- I find that Kah Motors (Honda distributor) lack much knowledge/ advice when it come to the HCH06! Do others in Australia / elsewhere face this problem??!
BTW- can we (Singaporean HCH2 owners) meet somewhere and exchange notes? preferably on Sunday? I would look forward to that.
