Fiat was hardly a resounding success when Marchionne took over, and we've already discussed Chrysler's toils, but perhaps the biggest part of Marchoinne's legacy will be the financial success he steered FCA towards.

In 2015, one year after FCA's founding, revenue was up by 18 percent, earnings before tax was up by 40 percent, and profit improved by a staggering 91 percent. This year, FCA beat forecasts and predictions by slicing its debt below £1.1 billion, while its operating profit rose again by five percent to £1.4 billion. It is finally expected to be in positive cashflow by the end of this year.

Now Fiat Chrysler is officially the world’s seventh largest car manufacturer. Not bad for something that just a few years prior was on the brink of disappearing altogether.
