Do Electric Cars Need Radiators? I am not too knowledgeable about electric cars, so I apologize if this is an obvious question. I know EVs produce significantly less heat than a conventional car, but do electric cars need radiators? I know the Nissan Leaf is air cooled (and let's be honest, it's not exactly "high performance" like a Tesla and thus needs even less cooling anyway), but Teslas are liquid cooled. Is there a radiator? And wouldn't high performance electric cars (future electric supercars/sports cars) need higher level liquid cooling systems and/or bigger radiators?
