DETROIT — Chrysler was collapsing when Fiat took control of the company just 19 months ago.

Now, under the Italian automaker’s detail-driven CEO, Chrysler is on the verge of turning its first profit since it filed for bankruptcy protection in 2009.

Chrysler Group on Monday said it dramatically narrowed its losses in the fourth quarter and 2010. And it predicted it would post net income of $200 million to $500 million for 2011.

Chief Executive Sergio Marchionne has transformed Chrysler by managing the smallest details, even picking the music for company presentations.

As a result, Chrysler’s vehicles are starting to look and drive better and the company’s costs are under control.

Marchionne, 58, a Canada-educated Italian who quickly replaces executives who don’t deliver, has brought back the speed and drive that Chrysler once had. He pushed engineers and designers to bring out 16 new or revamped models in the past year, including 11 in the fourth quarter alone.

Last year at this time, many Chrysler, Dodge and Jeep dealers were wondering if they’d even make it through the year. Sales were down and there were few new products on their lots. The company needed a $12.5 billion bailout from the government to survive in 2009. For years, it piled up debt and produced very few hit cars.

Carl Galeana, who runs dealerships in suburban Detroit, Florida and South Carolina, said he is impressed with the turnaround that Marchionne engineered.

“I think this guy is a visionary,” he said. “He talks about what he needs to do and he goes out and gets it done.”

Of the 16 new or revamped models, five were rebuilt from the ground up in under two years, far faster than the normal three or four years. They include the 300 big sedan, the Jeep Grand Cherokee and Dodge Durango SUVs, Dodge Charger muscle car and the Fiat 500 minicar.

Marchionne allowed engineers to make big changes, even if they added costs, said Doug Verley, chief engineer of the revamped Chrysler 200 midsize car.

Engineers were encouraged to make a case for new technology or designs, something that didn’t happen under Chrysler’s previous owners. As a result, the 200 has new features such as LED headlights and a quieter engine mounting system, a big improvement in quality that its predecessor, the Chrysler Sebring, didn’t have.

“The answer used to be no,” Verley said.

Along with quality, Marchionne pushed the 200 to come out faster. He personally approved the car’s interior in three days, far faster than the two weeks it took under previous CEOs.
