This is the 2nd review I've seen that calls the car "unsophisticated", and I think they're wrong -- unless their definition of sophisticated = hybrid.
Mitsu engineers put a lot of effort into building efficiency into this thing: from lightweight materials, to better than average aerodynamics, to reduced rolling and drivetrain resistance, to variable valve control, to start/stop, to 12v regen braking. Nothing unsophisticated in all that.
I know "unsophisticated" - my 1.0L 1998 Pontiac Firefly (Geo Metro) sitting in the driveway! It has none of those things.
