I am a Nissan Driver, though not a Latio driver. Honda's done a
fantastic job with their VTEC technology, but sadly, their interior
plastics/design doesn't correspond to their engine
technology.
Ride comfort wise etc, is not up to the price you pay for the Honda
marque either. Honda's been consistently priced higher than other
Jap saloons, together with Mazda, and i can only say that both
marques are overpriced.
Latios have been known to be extremely fuel efficient, with Latio
drivers reporting up to 15.6km/L. Take a look at this FC table,
extracted from feedback from drivers on mycarforum.
Nissan Latio 4AT 2005 Automatic 14.5 50% 50%
Nissan Latio Premium CVT 2005 Automatic 15 80% 20%
Nissan Latio Sport 2005 Automatic 15 50% 50%
Nissan Latio Sport without Sunroof 2005 Automatic 13 55% 45%
Nissan Latio 1.5L A 2005 Automatic 16.34 80% 20%
Nissan Latio 1.5 CVT Premium Sedan 2005 Automatic 13.5 50%
50%
Nissan Latio 1.5 A 2005 Automatic 13.5 50% 50%
Nissan Latio Sport 1.5 2005 Automatic 11 70% 30%
Nissan Latio Sport - Manual 14 50% 50%
13-15KM/L aint beyond them, in fact, i'd say its normal.
