Aoa;
Very interesting topic..........I would like to share my experience, the figures quoted are for Lahore (Gulberg, DHA & Garden Town) with 100% AC. Incl. Daytime rush hours;
Altis 2010 1.8 AT = 10.3 to 10.5 l/km.
Vitz 2003 1.0 AT = 10 ~ 12 l/km.
City 2005 1.3 MT = 10 ~ 12 l/km.
Civic 2013 1.8 AT = 10.5 ~ 11 l/km.
Alto 2007 VXR CNG (on petrol) = 9 ~ 10 l/km
These figures are average over last 6 months driven by same individual.
