Even as President Bush was outlining his own assessment on the impact of global warming to a skeptical Europe last week, automotive engineers in the U.S. and abroad have been racing to develop alternative fuel technologies for a cleaner atmosphere. But while most automotive manufacturers' entries are still on the testing circuit, Toyota has just announced what is believed to be the world’s largest range of environmentally friendly “hybrid“ vehicles. Toyota says it will have its new Fuel Cell Hybrid Vehicle, the FCHV-4, ready for commercial production in 2003. Now in road testing, the vehicle promises a top speed of 93 mph and range of 155 miles. Fuel cell technology produces less than one-tenth the emissions of a conventional gas-powered vehicle. General Motors and Toyota have joined forces to develop a fuel that can be used with either internal combustion engines or fuel cells. At the same time, Ford, DaimlerChrysler along with their fuel cell development partner Ballard Power Systems, and ARCO, Shell and Texaco have formed the California Fuel Cell Partnership for much the same purpose. It is the first time automotive companies and fuel suppliers are joining together to demonstrate fuel cell vehicles under real day-today driving conditions. Noting this momentum, Toyota is pressing ahead with development of its hybrid vehicles, particularly the FCHV-4 passenger car and the FCHV-BUS 1, a fuel cell bus that can hold more than 60 passengers and reach a top speed of up to 50 MPH.
