The results stemmed primarily from "higher shipment volumes and positive pricing, partially offset by higher industrial and launch-related costs," the company said.

Chrysler, which is controlled by Italy's Fiat SpA,  said its net income rose to $507 million from $436 million a year earlier. Net revenue jumped 7 percent to $18 billion.
