Since so many people are concerned guess its better to start a
thread dedicated to posting of FCs for all cars to make it a one
stop thread for readers to find out about FC. Post ur knowledge of
the different car's FC here.
Compiled from reading other threads and my own knowledge and
correct if necessary
Guys please put the FC for normal footing. Personally driving
lightfooted very tiring 
New Ford Focus 1.6 (thirsty fella) about 10km/l
Honda City 14-17km/l
Toyota Vios about 17km/l? not so sure
