DEARBORN, Mich. — Ford Motor Co. posted the worst quarterly performance in its history today, losing $8.67 billion in the second quarter.

The company also said it will retool two more North American truck and sport utility vehicle plants to build small, fuel-efficient vehicles, and it announced plans to bring six new small vehicles to North America from Europe by the end of 2012. The net loss includes $8.03 billion worth of write-offs because of a decline in value of North American assets and Ford Motor Credit Co. 's lease portfolio.

Even excluding those items, Ford lost 62 cents per share, worse than Wall Street expected.

Twelve analysts surveyed by Thomson Financial, on average, expected a 27 cent loss per share.

Including the write-downs, Ford lost $3. 88 per share in the April-June quarter, compared with net profit of $750 million, or 31 cents per share, in the same quarter a year ago.

The second-quarter loss surpassed Ford's previous record quarterly loss, $6.7 billion in the first quarter of 1992. Second-quarter revenue was $38.6 billion, down $5.6 billion from the year-ago period.

Analysts expected $34.6 billion. Ford has been successful selling cars in Europe, and the company is banking on the new European models to boost sales and revenue as it deals with a market shift from trucks to cars brought on by high gasoline prices.

The company said it has sufficient liquidity to weather the latest downturn in the U. S. auto market without additional borrowing. Wall Street wasn't impressed, at least initially. Ford shares dropped 38 cents, or 6.3 percent, to $5.65 in morning trading.

The company said it will retool the Michigan Truck plant in suburban Detroit, shifting its products from large SUVs to make global vehicles off the European Focus platform by 2010.

The SUVs made at Michigan Truck — the Lincoln Navigator and Ford Expedition — will be shifted to the Kentucky Truck plant in Louisville, which makes Ford Super Duty pickups.

The company also will retool the Louisville Assembly Plant, which now builds the Ford Explorer midsize SUV, to produce vehicles on the European Focus frame, starting in 2011.

The company had previously announced it would retool its pickup truck factory in Cuautitlan, Mexico, to build the Fiesta subcompact for North America starting in 2010.

Ford also said its Twin Cities Assembly Plant in St. Paul, Minn. , will continue producing the Ranger small pickup through 2011.

The plant was scheduled to close next year, but Ranger sales are down just 4 percent in the first half of this year, versus 18 percent for the U. S. light truck market as a whole.

The company said its write-offs included $5. 3 billion in North America and $2. 1 billion for Ford Credit's truck-heavy lease portfolio. Chief Financial Officer Don Leclair said most of the write-down was triggered by the drop in value of the company's truck and SUV inventory and lease residuals.

Ford reported a pretax loss of $1. 3 billion in North America because of the deteriorating U. S. market and the shift away from trucks. U. S. sales overall were down 10 percent in the first half of the year, with Ford's sales down 14 percent.

The company, though, continued to be profitable overseas, posting a $582 million profit in Europe and $388 million in South America.

The company also made $50 million at its Asia-Pacific-Africa division.

"The second half will continue to be challenging, but we have absolutely the right plan to respond to the changing business environment and begin to grow again for the long term," President and CEO Alan Mulally said in a statement. Ford said it does not expect a U. S. economic recovery to start until early 2010.

The company identified only three of the European small vehicles it will bring to North America: the Transit Connect small van, the European Focus and the subcompact Fiesta. Most will be built in North America, and Leclair said some might be exported. Ford already has announced that the Transit Connect will be imported from Turkey.

Ford said the other three vehicles would be identified later, including one that is unique within its segment.

Other possible vehicles are the Kuga small crossover, the C-Max small van and the Mondeo midsize car.

Ford also announced that the next-generation Ford Explorer midsize SUV will come out in 2010 and be built on car underpinnings, making it more fuel efficient than the current truck-based model. And it announced it will build a seven-passenger car-based crossover vehicle for Lincoln in mid-2009.
