The【C1】______ is not so simple, but there is little doubt that when GM pulled the plug on its EV1 battery-powered car a decade ago, other【C2】______ followed the Giant carmaker’s lead.
Yet GM has now 【C3】______ its enthusiasm for electric vehicles — or at least for their close cousins, hybrid cars (混合动力汽车). At the upcoming auto show, the company is expected to【C4】______ a prototype that overtakes existing hybrids,【C5】______ Toyota’s Pruis.

But GM’s new car is expected to be a "plug-in" hybrid, which, as its name implied, can be recharged by 【C9】______ it into the mains (干线). Together with a big battery pack, this provides a much larger range in all-electric【C10】______ , after which the petrol engine kicks in. GM’s car is expected to go around 50 miles (80 km) in all-electric mode,【C11】______ enough for American commuters, who would need to use the 【C12】______ engine on longer trips only. The【C13】______ is that plug-in hybrids need a much larger and more costly battery pack.【C14】______ a Pirus to operate as a plug-in hybrid, as some enthusiasts have done, costs around $12,000.
GM bosses have hinted that his company planned to put a plug-in into mass【C15】______ . It is an indication of how the pace is 【C16】______ in the race to develop more eco-friendly cars.
Others are more【C17】______ . Carlos Ghson, the boss of Renault and Nissan, who is 【C18】______ for his skepticism towards hybrids, said he still had doubts that hybrid technology is【C19】______ for the mass market, stressing that plug-in hybrids will have to wait until battery technology improves. Toyota has also been【C20】______ about plug-ins, insisting the Pims’ approach is more convenient. [br] 【C7】
