Fiat-controlled Chrysler has boosted third quarter 2012 net profit 80% year on year to $381m from $212m a year ago after sales rose 18% to $15.5bn. Operating profit grew 46% to $706m.

Worldwide vehicle shipments rose 19% to 559,000 in the quarter while sales were up 12% to 556,000.

The company said the results were due to “continued sales increases for the product lineup in total, including sales of the [new] Dodge Dart”.

“We’ve changed the conversation at Chrysler Group,” said chairman and CEO Sergio Marchionne in a statement, adding: “We are confirming guidance for the year.”

Nine month net profit was $1.3bn on sales up 22% to $48.6bn.
