17.An American company has developed a car powered by electricity that travels at high speed like cars powered by traditional fuels.Company officials say the car is experimental and will not be sold to the public for a long while.Yet some experts have called the vehicle(交通工具) an important step toward the production of pollution-free automobiles (汽车).The new car,called the Impact,was made by the General Motors company.Engineers say the Impact uses technology developed for the car that won the first international race for vehicles powered by sunlight.The Impact creat es no air pollution because its power comes from a large battery(电瓶).It can travel at a speed of 88 kilometers an hour.Then the battery must be refueled with more electricity.The battery can be refueled in a few hours with electric current (电流) from a person's house.It must be replaced completely every two years.The Impact has two motors.Each powers one of the front wheels.Reports say the car makes almost no noise at low speed.It makes a small noise as it goes faster.The Impact has a top speed of 160 kilometers an hour and it can go from zero to 96 kilometers an hour in eight seconds.That is faster than most gas-powered cars.The head of General Motors,Roger Smith,has not said how much the Impact might cost,but he says it would have to be competitive with other car prices.Mr Smith also says a few problems still remain.For example,the cost of operating the Impact today would be about twice that of other cars.Reports say the new electric car has raised hopes among environmental officials,especially in California.American car makers are hurrying to meet new air pollution laws in that state.General Motors says California would be the main market for the Impact.But the company says it would not produce the car at all unless people all over the United States wanted to buy it.Some company officials say the car could be in production within five years.
