Automakers put hydrogen on fast track

The Sequel uses fuel-cell technology that until now has not matched the overall performance of gasoline engines. GM is introducing the car at the North American International Auto Show in Detroit as rival companies make similar announcements.

Passengers at Dallas-Fort Worth International Airport will soon ride on buses with hydrogen-powered engines, Ford Motor Co. chief executive William Clay Ford Jr. is to announce today. Ford also is to announce plans to create three gasoline-electric hybrid vehicles for retail sale, and to rush the hybrid Mercury Mariner sport-utility vehicle to showrooms later this year — a year ahead of schedule to capitalize on consumer interest in hybrids
