A VW press event showing off the new hydrogen fuel cell powered Tiguan. The vehicle is one of only two concept prototypes in the world, and this one was flown in from Germany for its US debut. The event was originally intended to be a test-drive of the HyMotion Tiguan, but the vehicle was having “electrical problems” that kept it out for display only. It was a good opportunity to get under the hood of a fuel cell powered vehicle. The Tiguan HyMotion has an onboard carbon-fiber tank capable of storing 3.2 kg of compressed hydrogen, which gives it a range of about 160 miles. It has a lithium-ion battery that serves as auxiliary energy storage and is re-powered by braking energy or the fuel cell.
