Detroit, January 23 (Reuters)Ford Motor Co. (F. N) released the first one on Tuesdayof-Similar test car driven by compressed hydrogen and "plug" combinationBattery packs that can be charged with standard household wires. Concept car-A modified Ford Edge. Ford and other automakers have shown one of several technologies in Washington, D. C. C. The auto show aims to highlight their progress in driving gasoline alternatives, including ethanol and cleaningburning diesel. Ford said its advantage was the first self-driving hybrid car, which was powered from hydrogen fuel cells and could be charged through conventional power outlets. Plug-In vehicles with batteries that can be charged with standard power outlets, both the Environmental Protection person and the power company have given support as they promise to replace the automatic power supplyEnergy consumption from oil to the United StatesS. power grid. General Motors (GM)N) push forward with plugIn a self-designed hybrid, a small internal combustion engine is used to operate on electricity to provide charging as needed. GM says it will start producing Chevrolet Volt once it can produce lithiumThe ion battery needs to run the vehicle at a lower cost and higher performance, which was not expected until the end of the decade. Ford also said it had significant technical hurdles to overcome before selling new electric and hydrogen-fueled vehicles, noting that the manufacturing costs for any fuel cell vehicle were still as high as millions of dollars. "Commercial. . . Sue Cischke, vice president of environmental and safety engineering at Ford, said: "This is still an attractive but distant goal . ". Ford and General Motors are pushing for the development of eco-friendly cars in the United StatesS. Automakers want to break the link to natural gasExecutives and analysts said the truck ran out of oil, damaging car sales and brand image. Ford said that the "HySeries Drive" technology developed for edge test vehicles can provide energy equivalent to 41 miles per gallon when using compressed hydrogen. This car is 336 by one-volt lithium-The ion battery pack is capable of carrying 25 miles of edge using stored power, Ford said. The company says the car can speed up at 85 miles an hour. Ford developed the first hydrogen fuel cell vehicle in 2001. Many competitors, including Toyota Motor Corporation (7203. T) and Honda Motor Company (7267. T) fuel cell prototypes are also being developed. Paul Newton, an analyst at Global Insight, said the recent fall in oil prices could delay the development of such technologies. "There is no doubt that without the strong support of the government, these initiatives will hinder automobile companies such as GM and Ford, making auto companies such as Toyota and Honda have significant competition in some alternative technologies, he said in a note to customers. He added: "Even the success of the latter may be accompanied by the decline in fuel prices and the fact thatThe world cost of owning a hybrid is starting to soar, making the technology a niche fashion rather than a viable mainstream option.
