Elektromotory jsou mnohem \u00fa\u010dinn\u011bj\u0161\u00ed ne\u017e klasick\u00e9 spalovac\u00ed motory, a celkov\u011b jsou elektromobily zn\u00e1m\u00e9 p\u0159edev\u0161\u00edm d\u00edky sv\u00e9 ekologi\u010dnosti a tich\u00e9mu provozu. D\u016fle\u017eit\u00e9 je v\u0161ak pod\u00edvat se i na druhou stranu v\u011bci, pokrok v\u00a0oblasti akumul\u00e1tor\u016f vhodn\u00fdch do automobil\u016f zdaleka nepokro\u010dil natolik, aby mohly elektromobily zcela nahradit klasick\u00e9 vozy.<\/p>\n
