(单选题)
Which of the following statements is INCORRECT about hybrids?
A.Hybrids have a petrol engine and an electric motor.
B.When the vehicle slows and brakes, the kinetic-energy begins to recharge the cars.
C.Different from common cars, hybrids need more engine management.
D.Plug-in hybrids engine management is simple.
参考答案：D
参考解析：
细节理解题。根据第二段的第三句“Hybrids, which have both a petrol engine and an electric motor run by a battery that is recharged by capturing kinetic-energy as the vehicle slows or brakes, need more management than does a petrol engine alone”（混合动力车，同时具有汽油发动机与电动发动机，电池在汽车减速或刹车时通过动能转化而充电，但这需要投入较普通车更多的引擎管理。）可知A、B、C三项正确；根据第二段最后一句“Things get even harder with plug-in hybrids”（引擎的智能化管理更加繁琐）可知D项错误。故选D。
