i gurantee u city is not slow in any sense..anyway if u check
out the stats..they both accelerate to 100km/h in ard 11sec..its
all abt putting that power down on the road..dsi's torque comes
fast without having to rev the engine hard..
i wud say it again..optra is defintely a nono unless u r willing to
pay for high FC and maintainance..vios's FC is gd..but 3 ppl at the
back will be a reali squeeze trust mi.
Get the City..i m sure u wun regret like mi~ 
ITS THE SINGER..NOT THE SONG~
