The Fuel Cell Range Extended Electric Vehicle from the Austrian company Magna Steyr presents a driving concept using a fuel-cell range-extender that could be built into any vehicle, to guarantee long ranges at zero emissions.
The difference to other demonstrators is that a compact-size car can cover about 90 kilometers in purely electric mode with the on-board batteries, and more than 500 kilometers in combined hybrid operation using the hydrogen for the range-extender.
The FCREEV from Magna Steyr combines the advantages of two different alternative drives: fast fueling and the high-energy density of hydrogen as well as the available infrastructure for electric charging. Basically it is intended to demonstrate that the vehicle uses the electrical energy as far as it can - by calculating that most daily journeys are less than the intended range - to use hydrogen only if necessary; Which undoubtedly removes all the strains of reduced autonomy. If the charge level is reduced, the fuel-cell switches itself on to recharge the battery and thus to increase the absolute range.
