AUTONOMY NOT QUITE READY TO GO IT ALONE
General Motors has a working version of its Autonomy fuel-cell concept car less than a year after the company first showed the technology at the Detroit auto show last year. The Autonomy creatively packs all the fuel cell hardware—its electric motor, fuel cell stacks hydrogen storage tanks, and computer center—into a seven-inch thick chassis. The body rests on top, giving nearly unlimited design freedom since the engine no longer dictates the vehicle’s shape. Though many critics doubted the technology’s market potential, GM got a version of the car running several months ago at its Opel proving ground. But the car is clearly nowhere near ready for prime time. It can go a maximum of 90 miles before refueling and has a top speed of 40 miles per hour. GM says it could get the car to 100 mph easily, but will save that for a future generation of the test car. It uses the same fuel cell system as GM’s HydroGen 3 Opel Zafira compact minivan. The Autonomy, developed on GM’s $100 million a year fuel cell budget, doesn’t have a small electric motor on each wheel — it uses one big motor for the front wheels. But the next-generation car will take a stab at going with four motors, says Chris Borroni-Bird, Autonomy program director for GM.
