A 35% change in one month, when the production lines are being retooled for a new version of the most popular model… is nothing special. Because it was planned and couldn't be managed differently (except by stuffing inventories, which is stupid when you annonce a new model). This can easily be compensated with raising sales of the most popular vehicle being sold globally. That what's the Chinese market is proving already with ~130,000 units to be sold this quarter (same as last year).
