depends on what road you're driving  lo ... 8L/100km most probably 70% highway 30 % city .

if 100% city roads, then might  be 10l/100 km oso ...

to say economical or not, that is very subjective. plz dont compare with CITY or VIOS coz this if defferent segment car. and their weight is defferent too. Spectra5 has 16inch sports rim and many other gadgets on it. So far i feel its equipments are  more than enough for normal user.

Depend on driving I guess, if you always driving at high rev/speed, the 2.0 will be more fuel efficient.

a little update to the list... hoping that 2.0 is available to customer.
