someone done the 0-100 on ativa
put it side by side with Myvi, Ativa loss 

and your theory is wrong, torque curve is not linear and you need to have torque curve graph from Perodua to know what power it make during the 2400rpm

in city driving, Ativa felt easier cause torque come earlier but 0-100 not ativa strength

Driving repeated short distances, not very good.
Haven't tried fully finishing one tank but car shows 10.1km/l on average.
Not very good as in a far cry from official figures la.
