Whakarāpopototia te tuhinga:  Kua waihangahia e Audi he wahie diesel e kiia nei he 'kakariki' i hangaia ma te whakamahi i te whakakotahitanga o te wai me te waikura. I whakaahuatia e te kaihanga motokā tana whakatutukitanga hei 'hinuhinu o te heke mai' me te kii ka taea e ia te whakarato i te huarahi waro-kore o nga waka. I whakamahia e ngā tohunga te pūngao whakahou hei huri i te hāora me te wai ki tētahi momo hinu paraoa e mōhiotia ana ko te 'blue crude oil', i muri iho ka whakakoia ki te diesel. Panuku ki raro mō te ataata. E kii ana a Audi kua waihangahia e ia te wahie o te heke mai - diesel (e whakaaturia ana i runga ake nei) i hangaia mai i te wai me te warowaihā. I whakamahia e nga tohunga te kaha whakahou ki te huri i te warowaihā me te wai ki tetahi momo hinu paraoa e mohiotia ana ko te 'paraoa puru', ka oti i te hinu paraoa. Kua whakaaturia e ngā whakamātautau ka taea te whakaranu ki te hinu diesel mai i ngā pūngao kohuke, ka whakamahia rānei hei pūngao māna ake. Kua tīmata kē a Audi ki te whakamahi i te e-diesel hou hei whakaoho i te waka tūmatanui o te minita o te mātauranga me te rangahau o Tiamana a Dr Johanna Wanka. Ko Reiner Mangold, te tumuaki o te whanaketanga hua tauwhiro i Audi, i kii: "I te whakawhanaketanga o Audi e-diesel kei te whakatairanga matou i tetahi atu wahie i runga i te waikura e taea ai te nekehanga tawhiti-roa me te kore e pa ki te āhuarangi. I whakawhanakehia te wahie a Audi me Sunfire, he kamupene hangarau pūngao i Dresden. Hei hanga i te pūngao, ka wera tuatahi te wai hei hanga i te waipiro, ka wahia ki roto i te hauwai me te hāora e whakamahi ana i te hiko hiko-teitei. Mā te mahi i tēnei tukanga i ngā pāmahana i runga ake i te 800°C (1,472°F), ka pakaru te wai ki te pai ake i te pāmahana rūma. Kātahi ka kōkirihia te hauwai ki roto i tētahi pūkaha me te hāora hāora i te pēhanga tiketike me te pāmahana tiketike. Mā tēnei e tauhohenga ai ki te whakaputa i ngā hauwai waipiro mekameka roa. Ko ngā hauwai te wāhanga taketake o ngā pūngao kohuke katoa, engari ko ngā pūhui e hangaia ana i te pūkaha e mōhiotia ana ko te 'huamata kikorangi'. E kii ana a Audi ka taea te whakahaere i te mahinga katoa ma te whakamahi i te kaha whakahou, ka taea te whakatutuki me te kaha o te 70%. Ka taea te whakakoi i te hinu puru i runga i te huarahi rite ki te hinu paerewa ki te...
I whakamahia e te kaihanga waka Tiamana te pūngao whakahou hei huri i te hauotawa me te wai ki te hinu 'huamata puru' i whakakoia ai ki te hinu diesel. Ka taea te tango i te hāora hāora mai i te hau, i ngā tipu hiko rānei. E kī ana a Audi ko tōna e-diesel he hau-kore e kore e tāpiri ki te huringa āhuarangi. E ai ki ngā whakamātautau ka taea e ngā waka te rere māmā ake me te whakaputa i te iti ake o ngā poke.
