Under pressure from Chinese competitors, Stellantis and Renault are pushing hard to cut electric vehicle costs so they can have similar price tags and profit margins as fossil-fuel models.
Europe's automakers are trying to develop more affordable EVs, which are more expensive than combustion-engine equivalents, as electric car sales growth has slowed.
Along with concerns over a lack of available charging infrastructure, the high cost of EVs has become a significant barrier to broader mass adoption for zero-emission cars.
"If I were a short-termist, I could immediately increase my sales of electric vehicles simply by letting the margins slide," Stellantis CEO Carlos Tavares told reporters on Thursday after the company posted full-year results and warned of a turbulent year ahead.
