Cause electric hybrid vehicles technology was first developed on cars. Honda Prius was the first hybrid in serial production and had severe problems with electric drive. In the most developed country on hybrid cars Germany, there is the sophisticated BMW I8, its electric only range is 30 km, weight is 1.5 tons.
Tesla is the only electric driven car with dual electric motor front and rear AWD with almost 500 HP and weight 2.5 tons. Now you can calculate that its is not wise to build a hybrid at demand in a 16 ton vehicle , what for ?
Only for show and PR ?
There is nothing mentioned about HP or Kw , range and others. It seems for me a PR sheet.
How much HP the electric engine must have to move the maybe 16 ton HIZIR ? Nothing mentioned .
Also the original classic versions sheet is confusing, it is in Turkish/ Englisch but they use German abrreviation 400 PS, they talk about effective combustion but have only EURO 3, with EURO 3 you can't pass most big cities in Europe because it is a mudslinger.( They had to use HP in English and BG in Turkish. )
There are too much simple faults and too much expectations are aroused, that makes me suspicious.
Without proofable values and data nobody will order that vehicle and it will stay a protoype, as national hybrid car or TR-Jet which only existed on drawings. That's my point and not nonsense.
