One of Marchionne's key proposals is to spin off Fiat Automobiles and combine that as a newly listed company with Opel. Fiat has considered spinning off of its automobiles division, from which it derives half its revenues, for several years. But as well as separating the unit from Fiat's trucks and farming and construction equipment maker Case-New Holland, Fiat could now end up presiding over the world's second largest automaker, with about 80 billion euros ($106.3 billion) in revenue and annual sales of 6-7 million units, according to Thomson Reuters. Fiat is currently Europe's sixth largest carmaker by unit sales. General Motors Europe also includes British carmaker Vauxhall and Sweden's Saab. Since Saab is currently being re-organized under Swedish law it may be separated from the rest of GM's operations.
