Chrysler Group is promising a “significant” increase to its previously announced production cuts as parent company, DaimlerChrysler AG, revises its full-year earnings forecast to reflect a substantial third-quarter loss.

Chrysler had announced a third-quarter production cut of 65,000 to 75,000 units. “We are adding to that by a significant amount,” a spokesman says, confiding most of the new cuts will take place during the fourth quarter, but some will affect third-quarter totals.

He declines to reveal precise numbers, but adds the cuts will take shape several ways.

“Some plants are losing Saturdays, some are going off overtime,” he says.

Chrysler will announce the moves on a week-by-week basis “because the situation could change,” the spokesman adds.

Among the plants known to be affected is Chrysler’s site in Newark, DE, home to the Dodge Durango and new-for-’07 Chrysler Aspen. Both are fullsize SUVs.

Meanwhile, DaimlerChrysler reduces its full-year earnings forecast by €1 billion ($1.27 billion). It expects an operating profit of €5 billion ($6.34 billion).

Chrysler, which had expected a third-quarter shortfall of €500 million ($635 million), now anticipates a loss of €1.2 billion ($1.5 billion).

Chrysler, which had forecast a full-year profit, now is expected to record a full-year loss of €1 billion ($1.27 billion).
