hmmm...
i assume you've done these:
1. calculate FC same as us - wait fuel tank indicator light on,
then pump full tank, from pump station, record how much you pumped,
then travel and record total dist travelled until fuel tank
indicator light on again then do the division.
2. OD is turned on, ie the instrument light at panel "O/D off" is
NOT litted
else, even if the aircond is turned on you shd'nt be getting
9.6km/h, its worst than a 2L car. esp you have been light
footed.
how about try to monitor a while more, if still liddat you shd ask
TC to check out your car, think they have the diagnostic tool to
check.
the march is quite zippy in terms of pickup compared to other auto
transmissioned cars. i have driven other auto cars for a reasonable
amount of time honda accord, jaguar, volvo, cerato, corona, others.
the pickup of the march scores much better due to its
body-to-weight-ratio. high speed no need to say lar.
however you cannot compare it to a manual cars, its another kinda
game.
suggest you try to drive other auto cars and feel the comparison,
or we check out yours on march 12.
