DEARBORN, Mich. — Ford, the only Detroit automaker to dodge direct government aid and bankruptcy court, surprised investors with net income of nearly $1 billion in the third quarter and forecast a “solidly profitable” 2011.

The automaker said Monday earnings were fueled by U.S. market share gains, cost cuts and the Cash for Clunkers program, which drew flocks of buyers to showrooms this summer. Ford’s shares rose 53 cents, or 7.6 percent, to $7.53 in afternoon trading.

The latest results signal that Ford’s turnaround is on more solid ground. The company lost more than $14.6 billion last year and hasn’t posted a full-year profit since 2005. While it made a profit in the second quarter, that was mainly due to debt reductions that cut its interest payments.

Ford, based in Dearborn, Mich., reported third-quarter net income of $997 million, or 29 cents per share. Its profit forecast for 2011 was a step above previous guidance of break-even or better for the year.

Ford’s key North American car and truck division posted a pretax profit of $357 million, the division’s first quarter in the black since early 2005. Ford cited higher pricing, lower material costs and increased market share for the improvement.

Excluding one-time items, Ford earned 26 cents per share, blowing away analysts’ expectations of a loss of 12 cents.

The earnings came despite an $800 million revenue drop. But Ford said it cut costs by $1 billion during the quarter, accomplished through layoffs in North America and Europe, reduced pension and retiree health care costs and improvements in productivity and product development.

Chief financial officer Lewis Booth said the company took in $1.3 billion more than it spent in the quarter, an improvement over its $1 billion cash burn in the second quarter.

“That’s a huge deal,” Booth said.

Ford’s plan to create demand and get better prices for its products, coupled with cost cuts, gave the company confidence that it will make money in 2011, Booth said.

But Ford still faces obstacles in its turnaround. On Monday, the United Auto Workers union said its members overwhelmingly rejected a deal that would have brought Ford’s labor costs in line with rivals General Motors Corp. and Chrysler LLC.
