Land Rover has frozen production of two of its four models because of seasonal changes in demand.
Production of 2,500 Range Rovers and Defenders at its Solihull plant will be discontinued until April.
This will be offset by an increase in output in August and September, leaving total production figures for 1999 unchanged.
Production of the company’s two other vehicle lines at the Solihull plant will remain unchanged.
Rover owner BMW sees the move as a result of December’s flexible working deal, which introduced a four-day week and cut 2500 jobs from its UK Rover workforce.
Land Rover sold a record 153,000 vehicles last year.
