Tesla confirmed the shortened waiting time, first disclosed on the company’s Chinese website, citing the output ramp-up at its Shanghai plant as one of the reasons.

The automaker usually delivers more of its cars produced in Shanghai to Chinese customers in the latter half of each quarter, which also brings an acceleration in deliveries, the company said.

Tesla has completed a major upgrade of the production lines at its Shanghai plant, its most productive manufacturing hub, and is ramping up output with a target of making 22,000 Model 3 and Model Y cars combined each week.

Chief executive Elon Musk has said production is a bigger challenge for the company than demand. It is struggling to increase output in its Berlin and Texas plants, while production losses during a two-month Covid-19 lockdown in Shanghai hurt Tesla’s profit margin in the second quarter.

The company has stopped taking orders for its Cybertruck outside North America, and also for Model 3 Long Range vehicles in the United States and Canada, citing big delivery backlogs.
