prius 1.5 and civic hybrid 1.3, both are 110 hp peak, but acceleration varies throughout the range, because prius has bigger electric motor, and larger batteries to support it, and electric motors provide their peak torque throughout their rpm range, so prius would has more torque available at any instant. hence better acceleration. plus prius' shape although not catchy to eyes allows it to travel through air more easily at higher speed.
prius 1.8 is 134hp peak, but again it has more peak torque at any instant that combined with cvt tranny gives it a lead over r18 141 hp civics, which get their peak torque only for some few hundred rpm range.
