Efektiivse ja säästliku sõiduki üheks olulisemaks omaduseks on võimalikult väike õhutakistus. Seetõttu ehitas disainer Martin Aubé aerodünaamikat silmas pidades silindrikujulise elektriauto.
Tõhusa elektrimootoriga varustatud ja voolujoonelise auto nimeks pani Aubé HInterland1, vahendab Tartu Ülikooli tehnoloogiaportaal Novaator. Lisaks tõhusale elektrimootorile püüdis Aubé Hinterlandi juures saavutada võimalikult väikest õhutakistust. Kiirusel 120 km/h moodustab kere õhutakistus auto energiatarbimisest 75 protsenti, ülejäänud 25 protsenti annab rataste hõõrdetakistus. Seega on kere õhutakistuse vähendamine auto energiaefektiivsuse suurendamise võtmeküsimus. Hinterlandi masstootmise plaane hetkel veel ei ole. |
