Fiat is relying on Chrysler and its 39 consecutive monthly U.S. sales gains to sustain profit amid losses its European losses. Fiat's net income rose to 142 million euros from 32 million euros a year earlier. Without Chrysler, Fiat would have posted a loss of 247 million euros in the second quarter.
Fiat-Chrysler CEO Sergio Marchionne has scaled back investing in new models for Europe with the region's car market mired in a six-year slump. Fiat's car sales dropped 10 percent in Europe in the first half, worse than the 7 percent industrywide decline.
To become more global, Fiat is seeking to buy the remaining shares in Chrysler and merge with the U.S. carmaker. A merger would allow Fiat, which also owns the Alfa Romeo, Maserati and Ferrari brands, to tighten cooperation with Chrysler and its Dodge and Jeep nameplates.
