佢嘅engine 同普通1.5升engine 係唔同. 大部份嘅汽車都係用四衝程嘅Otto cycle engine, 而Prius用嘅engine係用Atkinson cycle engine, 引擎機軸轉一個圈就做晒入氣, 壓縮空氣同燃料, 點火引爆, 排氣呢四個步驟. 好處係慳油, 壞處就係唔可以釋放太多力量.
副engine本身亦調校到唔會踩到好高轉數, 做到慳油D, 所以亦唔會靠high-rev做到大馬力嘅數據.
不過Prius加埋個六十幾匹嘅電摩打, combined hybrid power都有一百一十幾匹, 好夠用喇. 而且摩打嘅扭力係一開就係peak torque, 所以起步都好敏捷.
