The global car-making group reportedly believe that the public is yet to accept the higher priced technology, and is holding out until demand from customers grows.
"Many customers want to reduce C02, but they aren't willing to change their lifestyle or pay the cost; yet," Mr Lee said.
“That might not happen for another decade.”
Mr Lee also said that the smaller petrol and diesel engine strategy would produce better fuel economy for Chrysler models sooner, and that the carmaker would continue to improve the less efficient parts of its cars.
Fiat’s only EV – the 500e – is sold exclusively in California for the same price as a petrol-powered Fiat 500.
Fiat-Chrysler boss Sergio Marchionne said earlier this year that the company was losing US $10,000 on each 500e that it sold.
This fact, plus the latest reports, would suggest that Fiat-Chrysler isn’t planning to introduce the EV into other markets anytime soon.
