Ford Abandoned Electric Vehicle
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 1 999, 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¡ªseater 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 l£¬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 53 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 Toyot~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¡ªonly engines , and the batteries recharge themselves. Ford says it thinks such vehicles will help it meet planned new guidelines¡°on vehicle emissions¡± in the U.S.
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¡ªmakers to offer 100£¬000 zero-emission and other low¡ªemission vehicles in the state by 2003£®Car manufacturers hope the legislation will be rewritten to allow for more low--emission£¬rather than zero¡ªemission£¬vehicles£®
