Marchionne's comments came as Fiat Chrysler reported improved earnings for the fourth quarter and for 2016 as a whole.
For the full year, it saw net profit jump to 1.81 billion euros (USD 1.92 billion) from 93 million euros in 2015 as a more profitable model mix and lower costs helped overcome a sales decline in North American markets.
The earnings mean an average profit-sharing bonus of USD 5,000 for 40,000 US workers. The money will go to eligible employees represented by the United Auto Workers' union.
The company also showed improvements in the highly competitive European market, where it increased its share of sales by 0.4 percentage points. Profits also jumped at its luxury Maserati brand.
For the fourth quarter of 2016, global net profit more than doubled to 409 million euros from 196 million euros in the same quarter a year earlier. That was short of analyst expectations for 610 million euros, as compiled by financial information provider FactSet.
