GM HydroGen4 Concept unveiled with 199 mile range

GM announced today that its new HydroGen4 fuel-cell vehicle is ready for real-world testing. Nine companies in the Berlin area will be participating in GM’s zero-emission test program. The fourth-generation fuel-cell vehicle is the result of 10 years of development and work with hydrogen and fuel-cell technology and is a part of a program that has already logged 434,959 miles in global testing.

The new GM HydroGen4 fuel-cell vehicle uses 440 single cells which combines hydrogen and oxygen from the air to produce electricity. The fuel-cell stack provides power to the 98-hp electric-motor allowing for a 0 to 62 mph time of 12 seconds and a top speed of 100 mph. The HydroGen4 is also fitted with a 1.8 kWh buffer battery to store extra energy from a regenerative braking system. The carbon fiber tanks hold 4.2 kg of hydrogen at a pressure of 700 bars allowing for 199 mile range.

GM says that its HydroGen4 can start and run in sub-zero temperatures and is designed to be as safe as conventional vehicle.
