As the power source of the future, hydrogen andoxygen are combined in the fuel cell to form pure water. Energy is released in this "cold combustion" process – drive energy for an electric motor that turns with zero emissions. The front wheel drive Golf SportWagen HyMotion accelerates to 62 mph in 10.0 seconds. The hydrogen is stored safely in four high-tech carbon-fibre tanks, which are located in a space-saving way in the underbody. Their fuel capacity enables a driving range of 310 miles. Refilling ofthe fuel tank of the concept car takes just three minutes. The key drive components of the Golf SportWagen HyMotion were developed by Volkswagen Group Research in Germany. The fuel cell system, which hasa driving power of 100 kW, was conceptualised at the Volkswagen Technology Centre for Electric Traction. In addition, the concept car has a high-voltage lithium-ion battery, which stores the kinetic energy recovered from regenerative braking, assists in the starting phase of the fuel cell and adds a dynamic boost to the maximum acceleration of the Golf SportWagen. The fuel cell andbattery drive an electric motor adapted from the e-Golf.
