It's actually d replacement model 4 Echo where using d same
engine with Daithatsu Gino (or, kelisa), 1.0 3 cylinder DOHC 12V
with VVTi technology. There's also a 1.3 DOHC 16V VVTi series,
using d same engine as Daihatsu YRV.
Toyota Passo = Daihatsu Boon (both d same car).
U may check out daihatsu or toyota website 4 further details. Quite
a fun car 
But selling @ $64000 is quite x. With tis $ u can actually go 4 a
vios already which is 1.5 VVTi, more power and space.
