Ford Abandons Electric Vehicles
The Ford motor company's abandonment of electric cars effectively signals the end of the road for the technology, analysts say.
General Motors and Honda ceased production of battery-powered cars in 1999, to focus on fuel cell and hybrid electric gasoline engines, which are more attractive to the consumer. Ford has now announced it will do the same.
Three years ago, the company introduced the Think City two-seater car and a golf cart called the THINK, or Think Neighbor It hoped to sell 5,000 cars each year and 10,000 carts. But a lack of demand means only about 1,000 of the cars have been produced, and less than 1,700 carts have been sold so far in 2002.
"The bottom line is we don't believe that this is the future of environment transport for the mass market," Tim Holmes of Ford Europe said on Friday. "We feel we have given electric our best shot."
The Think City has a range of only about 55 miles and up to a six-hour battery recharge time. General Motors' EVI electric vehicle also had a limited range, of about 100 miles.
The very expensive batteries also mean electric cars cost much more than petrol-powered alternatives. An electric Toyota RAV4 EV vehicle costs over $42,000 in the US, compared with just $17,000 for the petrol version. Toyota and Nissan are, now the only major auto manufacturers to produce electric vehicles.
"There is a feeling that battery electric has been given its chance. Ford now has to move on with its hybrid program, and that is what we will be judging them on," Roger Higman, a senior transport campaigner at UK Friends of the Earth, told the Environment News Service.
Hybrid cars introduced by Toyota and Honda in the past few years have sold well. Hybrid engines offer greater mileage than petrol-only engines, and the batteries recharge themselves. Ford says it thinks such vehicles will help it meet planned new guidelines on vehicle emissions in the US.
However, it is not yet clear exactly what those guidelines will permit. In June, General Motors and Daimler Chrysler won a court injunction, delaying by two years Californian legislation requiring car-makers to offer 100,000 zero-emission and other low-emission vehicles in the state by 2003. Car manufacturers hope the legislation will be rewritten to allow for more low-emission, rather than zero-emission, vehicles.
What have the Ford motor company, General Motor's and Honda done concerning electric cars？
A．They have started to produce electric cars.
B．They have done extensive research on electric cars.
C．They have given up producing electric cars.
D．They have produced thousands of electric cars.

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.
Today's hybrids capture energy normally【C6】______ during braking and coasting and use it to power an electric motor that can provide extra bursts of【C7】______ when needed. The Pruis and other hybrids can also run【C8】______ battery power alone at low speeds over short distances, such as in stop-start traffic.
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.

Electric Cars: Low-impact Vehicle
After years of false starts, General Motors has at last set a date for putting its first battery-powered car into production. The EV1 that will roll out of GM's factory in Lansing, Michigan, later this year will be the first car in modern times to have been specifically designed by a big car maker to run on electricity.
A proper marketing of electric cars？
The timing is intriguing. GM has announced its decision just as California's regulators are preparing to relax the strict air quality standards that were an important reason for going ahead with the project in the first place. The California Air Resources Board decided in 1990 that 2% of the vehicles sold in that state by the seven companies with the largest market share would have to be emission-free — in other words — electric-starting in 1998. By 2003, the board wanted the figure to be 10%. Now it admits that "new studies" have shown what everyone else knew all along: that its mandate (命令)would be impossible to meet using existing battery technology.
Many challenges faced
This is because without official bullying, people are reluctant to buy electric cars. Although the EV1 has been loaded with all sorts of baubles(花哨的小玩意儿) — dual air bags, air conditioning, power windows, even a CD stereo system — it is far from clear that these will compensate for a puny range, the basic flaw of every electrical vehicle. Publicly, GM officials claim that the car will have to be recharged every 145 km (90 miles) or so, but they concede privately that the real figure is likely to be close to 100 km. Without access to a high-speed charger, such a refill will take around 15 hours.
Even squeezing this much range out of the EV1 has required a lot of engineering sleight (灵巧)of hand. Around 400 kg (900 lb) of lead-acid batteries are secreted about its body. To help compensate for all this weight, and to maximize the distance it can cover, the vehicle is equipped with low-rolling- resistance tyres, an aluminum chassis (底盘), a wind-cheating plastic skin and a regenerative braking system that helps to recapture energy normally lost when the brakes are applied. Even the tear-drop body shape should cut down wind resistance.
Owners of an EV1 will have two ways of charging it. Those without access to a g20-volt power supply (most American domestic circuits are 110 volts) will have to do it the hard, 15-hour, way by plugging into a normal socket in the boot. But the preferred method is more ingenious(巧妙的): use of a paddle-like contraption (发明) that is inserted into a small slot in the car's nose. This operates by induction(电磁感应), eliminating the risk of sparks that might ignite the hydrogen released during recharging.
At 220 volts the paddle can give an EV1 the electrical equivalent of a full tank in three hours. Super-charged versions of the device, designed for use in service stations, shopping-malls and fast-food restaurants, can bring the batteries up to 80% strength in mere 15 minutes. The fate of the EV1 could therefore be determined by GM's success in convincing the owners of such establishments to install these special chargers, thus creating a convenient alternative to petrol pumps for keeping a car fuelled up.
The EV1 will be sold at a price of $ 35,000 through GM's Saturn dealerships and, in an unusual move, under the GM brand — the first time a product has been sold using the corporation's own name. It will initially be available only in four cities in southern California and Arizona. Environmental regulators in several other smog-bound states are also hoping to develop a market for electric vehicles, but GM's engineers feel that the EV1's lead-acid batteries would not function well in the sort of frigid conditions now blanketing the north-eastern states. Cold weather reduces a battery's power and life, and increases tyre fri
