MILAN, Italy -- Italian carmaker Fiat says second-quarter net income more than quadrupled thanks to strong sales by U.S. subsidiary Chrysler.

Fiat on Tuesday posted a second-quarter net profit of $188 million, up from a restated profit of 32 million euros in the same period last year. Without Chrysler, Fiat would have lost 247 million euros, as European sales dropped 5 per cent.

Worldwide car shipments were up 5 per cent in the quarter, to 1.2 million units. North American sales rose 4 per cent, while Asia and Latin America posted double-digit growth.

First-half profits dropped 12 per cent to 59 million euros.

Fiat confirmed its 2013 targets of a trading profit between 1.2 billion euros to 1.5 billion euros on revenues of at least 88 billion euros.
