DETROIT – Chrysler rode big sales increases in the U.S. to a $436 million profit in the second quarter.

A year earlier, the company lost $370 million, mainly because it refinanced government bailout loans

Unlike other U.S.-based automakers, Chrysler is benefiting from its reliance on the United States car market. While other companies are losing money in Europe, Chrysler has little presence there. The company gets 75 percent of its sales from the U.S., where the market has been growing for the past three years.
