使用燃油驱动内燃机加上电池驱动电动机的混合动力车称为油电混合动力车(Hybrid electric vehicle,简称HEV),目前市面上的混合动力车多属此种。油电混合动力车普遍比同型纯内燃机车辆有更好的燃油效率及加速表现,被视为较环保的选择,而缺点在于售价较高、动力系统占用空间较大、电池的寿命受限等。
A hybrid vehicle uses two or more distinct types of power, such as internal combustion engine+electric motor, e.g. in diesel-electric trains using diesel engines and electricity from overhead lines, and submarines that use diesels when surfaced and batteries when submerged.
Other means to store energy include pressurized fluid, in hydraulic hybrids.
