Test drive Opel Zafira hydrogen fuel cell car

Only gas pedal and brake. No gearshift but only push buttons for Forward, Backward and parkings. Thus it is a matter of disusing the left foot for the test run for the first time.

Heating

It has only 11 degrees. Warm air flows out of the heating. Where from? The fuel cell converts a part of the energy into electric power, the rest is warmth. Although the efficiency of the fuel cells is much better than with a diesel engine, more heat is left for the vehicle heating. The diesel engine blows a lot of warmth with the waste gases behind out. Hence, the hydrogen Zafira nobody needs additional heating systems like with modern diesel cars usually.

Bicycle with neutral

If one of the gas goes it feels like a bicycle in the neutral. The car rolls simply farther. There is therefore no engine brake. The brake assembly was dimensioned, so, increasingly.

Consuming at the traffic light

About 2 kW are also used in the traffic light to hold the fuel cells fully operationally. So it remains actual to save fuel by turning off the ignigtion key at the traffic light.
