for normal day to day driving, the honda city will have better
performance, since its maximum power is @5500rpm and max. torque
@2700rpm, as compared with 6000rpm and 4200rpm for the vios.
if u opt for the manual version, the city's gearshift is much
better than the vios, which is not as smooth
as for space, the honda city is much more roomier and has more
headroom...the seats are more comfortable in the city than the
vios, as the seats in the vios are rather short.
