Citroen has done better than Peugeot and Renault, helped by its aggressive pricing strategy and a recently refreshed model line-up, with output slipping my just 1% last month compared to the same period last year.
Peugeot has suffered the worse sales, posting a 5% fall in year-on-year volume, while Renault's production has fallen by more than a fifth.
Renault has been hit by disappointing sales for the new Laguna along with slow demand for the Espace and Vel Satis (latter is still sold in Europe and not in UK). The current Megane is also running out to replacement, further depressing the figures. The company is considering reducing production at the Sandouville plant, which produces the Laguna, Espace and Vel Satis, to just one shift.
Despite the sliding sales, Renault boss Carlos Ghosn has said he is confident that the manufacturer will meet its operating profit target for this year.
